Title: Limp Home Mode
Post by: Mike SX on November 29, 2012, 13:16:25
2009 CRDi Manual CW, intermittently into limp home mode for about a year, Dealership said "could be fuel line fault", this fault was "rectified", and recorded as "Historical". They also reset the ECU. Since gone into limp mode 11 more times, and recovered before I could return to the dealership.  I have returned the vehicle yet  again and they have now rang and asked me to collect the car and use it for sometime with the Cruise Control disconnected, and test it for them!  This "could be the problem". Cruise Control was included in the original purchase of this new i30. They have also replaced the brake light stop switch twice, apart from several other unrelated issues.
The vehicle is now unreliable for any use and they now say that there is  "little more they could do".

Anybody have any other ideas? I would appreciate any feedback.

Oh, those damn periodically faults are so fuc...g hard to solve.

I do understand that you don't want to have your car back.

Let the mechanic/tech that is working on your car, drive it to/from work, if it doesn't give you any insurance problems. Then he can have the computer attached to your car while driving it, and hopefully be able to register the fault.

Alternatively, if your dealer say they can't fix it, demand that the tech's from the Hy HQ come and assist/take your car to their workshop.

For us to help, we would need some details about exactly when or what triggers limp mode. You need to do some detective work and detail as much info as possible, otherwise we will only be guessing. Sounds like the dealer needs the car to be driven, which is why they want to return it to you. I'd take it back and drive it myself rather than have them "test driving" it to who knows where.

There will be codes stored in the ECU for these faults. It would be interesting to see which ones show up when the OBD port is accessed.
Title: Re: Limp Mode
Post by: Mike SX on November 29, 2012, 14:59:37
During the past year, all these have been tried. When I have asked which codes were generated, I have been told "only historical", no fault code shown ! They return the car with the ECU "cleared" - as if the fault has been corrected!
This doesn't sound correct to me, it's obvious there has been a fault, so what is the point of recording it, unless it can point you in the correct direction,  ie. No on board diagnosis available ?
Seems strange.

Hi Interphase, Nice to see you on but sad it is in these circumstances  :Pout:

I assume you have tried Hyundai UK for assistance (otherwise that has to be the next step)

Extremely frustrating (sure sounds like Fuel system issue to me) When the problem occurs does it only rev to 3000RPM ?

What actual occurs when it goes into limp mode?

We will do all we can to help diagnose (although it is difficult)  :undecided:
Title: Re: Limp Mode
Post by: Mike SX on November 29, 2012, 15:48:52
Thanks Dazz.
Yep, maybe fuel (whatever), that was my thoughts. It is flat out at approx. 30mph in the 4th. Intially they thought it could be water in the fuel filter, but they say all ok. They have always serviced the vehicle; as it was due. Engine runs fine, starts easily, just won't rev.
On two occaisions, it has occured when the fuel guage indicates just under half.

No specific advice on the i30 but over various other cars I've seen go in limp home mode intermittently it's been mass air flow meter or crankshaft sensor.  Only easy to diagnose by pulling the codes as other have said. There are probably at least 6 sensor failures that can cause it.

On two occaisions, it has occured when the fuel guage indicates just under half, and I have simultaneously floored it.
I usually fill with Esso.

The reason I specifically mentioned 3000RPM is this is the maximum revs the engine will rev to if there is a fuel system failure as per what happened to BOB (Ouri30) in the early days of this club.. From memory his car went into limp mode after that.

They had to replace some components of the fuel system as well as the filter to fix it .. I will try and find a link to his thread. Might be a different problem but sounds similar  :undecided:

Thanks Dazz, I have previously read these reports, one is significant; if you accelerate around a fairly tight corner, under half full, the problem manifests.
I have tried to tell the Service Receptionist, who repeatedly, as I have noted, does not absorb this helpful information.

You need to bypass the receptionist, make name contact with the service manager and log your details in written form and provide this when the car is in for repairs. The more info you can give them, the quicker they can find / fix what is wrong, it's win / win for you both.

We have a champion owner of i30cw CRDI 1.6 4AT here, who (also a member of this club but seldom make posts) faced similar problem for 14 times, and some also for several times. After a series of repeat inspection and testing by the dealer for many months, fortunately I did not hear similar issue recently.

From the information they released, seems about fuel filter system, something like the density of the filter material inside the filter housing. Density of old type filter was higher than new type filter (though they looks the same). Service centers already changed to supply new filters, and meanwhile re-ensure the correct procedure of installing/changing the fuel filter, to make sure smooth fuel flow through the filter system and preventing possible air existed in there.

Just for reference, because I did not participated the inspection/testing activities.

Just spoken with the Dealership Owner, the fault code & GSW indicate 2 related problems; the cruise control unit & accelerator pedal unit.
Hyundai (UK) are unwilling to allow both unit replacements simultaneously, so the cruise control module will be replaced next week - as a process of elimination, ie. the customer becomes a manual  ECU, thereby assisting Hyundai GSW etc.
He stated that they had already rectified a previous i30 with this issue, by replacing the c/c module.
It's a pity that Service Reception failed to remember, and explain as such.
Thank you all for the input.

Good luck mate. My wife had issues with a Holden Viva which would go into limp mode but by the time we got it to the mechanics the first few times it was fine again. No codes found. We kept getting your to drive it until it went back into limp mode. After I reckon 10 times I said that enough was enough and got it towed to the mechanics while in limp mode. Still no code found. Turned out they didn't even have the correct scan tool for our car... Eventually they got the right tool but had been driving it to see what happened and the fault cleared itself again...

Longer story shorter, the car just died one day and wouldn't start again. Horrible situation. Got it towed again and was told that the piston had basically smashed the head. it was going to cost $2000 to get it fixed. It could have possibly been sold for $4500 when fixed but ended up selling it broken for $2000 to a car yard to save the hassle.

That's a terrible story Aaron  :disapp: :fum:
My sentiments exactly.
I'm still not convinced that it is the cruise control/accelerator mechanism, but I'm not party to any codes etc.
Twice, when pulling out of a junction & turning sharply, under half full, limp mode operates.
Not a good time when you need to accelerate into a constant line of traffic.
So I will keep the vehicle under half full and regularly check it.
Collecting the vehicle today.

In all seriousness though a drop in power when pulling out into traffic is a real worry (and a safety issue)  :fum:

I had the same issue with mine going into limp mode after my brake light switch was replaced. It turned out to be a faulty brake booster, the brakes were being applied after a short time of driving. the ESP system shuts the throttle off if the system thinks you are BOTH accelerating & braking & puts the car into limp mode. I hopefully get  my car  back sometime this week from being repaired.
Title: Re: Limp Home Mode

Limp Home Mode has started again.

Braking, then accelerating out of a slow left hand turn, with the tank full.
(Previous occasions, under half full, and right hand turn).
ESP comes on, initially hesitant on acceleration, then into Limp Home Mode. Lifting foot off pedal seems to clear itself and accelerates, ESP light still on, pull up, switch off, starts working OK for a short time :(

Back to Dealership, yet again.....

Sympathy to all those suffering Limp home mode.

I've had the same issue and fingers crossed it is now resolved.  After having this go on for some months my vehicle was finally (after some incorrect diagnosis's and head scratching) diagnosed with a 'Fuel Bug'(cladosporium resinae).  At first I was skeptical and thought that the dealer was trying to shirk their responsibility.  The dealers fix was to drain the tank, flush and refuel at my $600 expense.  The dealer emailled me some photo's of the fuel sample and a black growth could be seen in the fuel.  I told the dealer not to go ahead with their fix and did my own research, mainly on here!

I found out about a product called Fuelmaster and gave the company a ring and told them of my predicament.  They told me straight up that they were glad I called as they could save me some money!  Apparently the fuel bug is quite common (increasingly so) and is easily treated.  Draining the tank and refilling was not going to solve the problem as the bug needs to be killed otherwise it would just breed up again.  I have since taken delivery of the fuel master added a healthy dose 100ml (well over the usual dosing of 2.5ml per 10L) and re-filled the tank to the brim with caltex vortex then left the vehicle for the weekend.  The fuel master works by bonding any water in the tank to the fuel molecules so that it can be passed through the engine and burnt normally.  The water in the tank is the problem as the fuel bug grows on the interface between the water and the fuel, with no water in the tank the bug cant feed and dies.  My vehicles symptoms were worse when the tank was low presumably as this was when the intake was sucking in more of the bug.

It's early days but my vehicle is running better than it has in a long time, apparently any of the dead black fungal material left in the tank will be collected by the diesel fuel filter.

SO far so good.  If anyone out the is having problems such as the 3000 rpm cut out or the engine losing power and cutting out I strongly suggest you give a fuel treatment such as fuelmaster a go.  Fuelmaster is not cheap at $70 per litre, but is does treat 4000L of fuel so will hopefully keep my diesel tanks bug free for some time.

Circumstances has prevented me from returning the vehicle yet.
The fuel problem is interesting, usually happened when under quarter full, never happened brimmed up, but this occasion I only filled to three quarter, (only had £50 on me), drove 10/20 miles - went into limp home mode. Cleared itself on next morning start up. At some point I will have to return it, in the meantime it's more sensible if locally used, rather than a dealer using it as a possible pool car "on test", returning it as "fault code cleared", empty etc.
Maybe something "permanent" will happen before I return it, just hope I'll be lucky with the location.

Just happened to be near the Dealership today when the Engine Management warning light, (on this occasion), remained illuminated - instead of the usual ESP illuminating/off/on/off/on/off & with frequent bouts of LHM, then "clearing" itself whilst accelerating, and EM light occasionally illuminated; not necessarily at the same time as the other two.

Left the vehicle running, Technician connected up the OBD and announced that it indicated a faulty accelerator position sensor. Just lately, when stationary, with the ESP light on the vehicle would tickover at 1200 revs, the ESP light would even illuminate when coasting, things changed daily.

He will obtain a replacement, book the vehicle in for 2 days, (presumably to test), and carry out the work.

SO far so good.  If anyone out the is having problems such as the 3000 rpm cut out or the engine losing power and cutting out I strongly suggest you give a fuel treatment such as fuelmaster a go.  Fuelmaster is not cheap at $70 per litre, but is does treat 4000L of fuel so will hopefully keep my diesel tanks bug free for some time.


I've now put two tanks of fuel through my car since I started using the fuel treatment.  I must say I am impressed.  I have had NO reoccurrence of the engine cutting out or being limited to 3000rpm.  The fuel economy for the first tank (which I dosed with 100ml of fuelmaster - 5 times what was needed) was 5l/100km - This is the best ever fuel economy that i've achieved by a long margin!  The second tank (dosed with 12.5ml) I received 5.2l/100km the second best fuel economy that I've achieved!  Not sure what fuel economy others get but I used to get about 6l/100km from mainly highway driving with 20% town running.

I've started using this product in my XTRAIL also.  I would really like to see dealers recommend this product rather than offer to drain tank for $600 which may not even fix the problem! :)

Good work Phil, just ordered some of those containers myself!  I have been using a 20ml syringe but these are much more convenient. Have you noticed any change in fuel economy?  The company is quite conservative and doesn't really claim that there will be an improvement - but I am quite impressed with my improvement.

Just not sure where you could safely purchase this product here in the UK.

After several failed prior attempts to solve the problem, i30 booked in for a replacement accelerator pedal position sensor on Tuesday 9th April :confused:

It looks like in the UK you have a product called Star Brite Biodiesel that looks similar. Here is a link to a great article comparing UK diesel bug treatments. http://www.marine16.co.uk/acatalog/diesel_bug_pbo_test1.pdf (http://www.marine16.co.uk/acatalog/diesel_bug_pbo_test1.pdf)

You are better to use a product that gets ride of the water (bonds with fuel molecules) rather than just a biocide.  This will prevent any water damage to the injectors.

.Are these not one & the same thing?

No not the same.
It must be under bonnet, not sure where exactly, they now only "need the car for 45 minutes".  They mentioned it could also be this item during last visit, but said Hyundai would only allow 1 thing at a time, and sent me a letter to return it if still faulty, and subsequently offering "a good exchange price" for the vehicle.
Now on the 3rd brake light switch. I have not posted all the vehicle return faults, but there have been other issues, been too busy to "whinge". The ESP light can even illuminate when stationary, as the engine revs climb.
When entering a busy roundabout etc., if in LHM, I have to switch off, coast, and restart in order to accelerate away, especially on any incline :eek: EM light illuminates constantly.
The Service Manager is aware, but  have still had to wait for repairs.

Just to clarify the situation, the paramount problem is that very little power is available; the lack of revs. would not present too much of a problem, indeed it would still be easy to break the national speed limit DOWNHILL.

The vehicle struggles up the slightest incline, and as it slows down, you would be lucky to reach 1750 rpm in any gear :eek:

It simply refuses to accelerate and pull away at even a reasonable pace.
 
Totally unusable on fast dual carriage or motorways......

You should ask them to check for a fuel bug.  Only problem is that they may bill you for their work as fuel bug / contamination is not covered by warranty (so I found out!) A quick dose of any diesel fuel treatment will let you know after about 24hrs.  Might save you some hassle.

Commencing with the dealership owner, I asked them all if they had heard of the diesel fuel bug.
None had.

However, the local oil heating tanker delivery drivers, and their office staff had, they used it to decontaminate Domestic & Commercial Oil Heating Tanks, and the respective fuel lines, (into the Oil Boilers), Farm Tractors, Generators, Pumps, etc.

However, I do realise that exactly the same product may not be suitable for my i30.

Thanks Phil, but I feel that the Dealership should make a final attempt to fix it.

Throttle position sensor replaced within the advised 45 minutes on Tuesday 9th April, and all hinges and locking mechanisms  lubricated :confused:

All round tyre pressures unchanged at 32psi, (ESP light).

Keeping fuel level tank low, (to provoke the fuel bug).

Ok so far, (but early days).

I found out about a product called Fuelmaster and gave the company a ring and told them of my predicament.   If anyone out the is having problems such as the 3000 rpm cut out or the engine losing power and cutting out I strongly suggest you give a fuel treatment such as fuelmaster a go.  Fuelmaster is not cheap at $70 per litre, but is does treat 4000L of fuel so will hopefully keep my diesel tanks bug free for some time.

I have approached them and this is the reply:-

I’m sorry we do not have a distributor or a re-seller in the U.K. The product is only sold in Australia & New Zealand so far.

Just an update, still using other vehicles - unable to trust this i30, no time available at the moment to return to Dealership, (been 2 years on/off LHM).
But each day I start the i30 as a "test", I touch nothing but the door to get in and the key to start the vehicle, I do nothing else, ie. release handbrake, engage a gear, or even close the door etc.
Some days it immediately enters Limp Home Mode, some days it doesn't, this does not necessarily concur with the ESP light, which is sometimes On sometimes Off.

When in LHM the tickover speed is 1250 RPM - so you soon realise.

Nope, not me, but next week I hope to "remove/disconnect" the Hyundai Approved Cruise Control, fitted new by the Dealership.

Since Surferdude on 28th May, mentioned they were different from Factory fitted, (no need to touch brake pedal to engage, etc), I now gather that my system has an independent CPU which is linked to the CAN Bus, maybe, (as in the addressable analogue systems), it can record the incorrect fault code; once before the fault code recorded inaccurately, low engine oil, accelerator position switch etc.

Although this is the 2nd Cruise Control unit fitted, maybe there could remain a software issue, and I wondered if anyone else had a problem with using this approved accessory on a diesel.

Yet another unbelievable update.

As arranged Dealership disconnected the Cruise Control on 8th July, having carried out approx. 1000 miles with no problems, I informed them 10 days ago, that all had been ok.
They asked me whether "I really use c/c"! Yes, I said, now after 2 years and 18 return visits, losing a day each time, and the vehicle unusable for 10 months of the year, can you please FINALLY rectify this problem. They asked ME what to do! I said contact Hyundai, either update the software and/or replace the c/c unit, (again). Bring it in Wednesday 31st July they asked. I said if there are any problems let me know. No further contact from them whatsoever.
Took yet another day off, returned with the car, I asked them what they were going to do.
Just reconnect the c/c for me so I could use it, nothing else, but that's causing the faults, they looked at me blankly, and asked if I was really sure, as they had no idea - what a wind up.
They said that since Hyundai had replaced the c/c unit once there was nothing further they could do.
The New Vehicle Sales Manager will contact me tomorrow, they may give me a good trade in price against a new vehicle!!!!!!

If Hyundai management in Korea or wherever are REALLY serious about competing with current Premium brands on quality AND price, they simply cannot afford to do nothing.  Too many people with influence will be waiting to say "I told you so" if Hyundai fail. In the same Auto express this week, in reference to a used i20, it was stated that Hyundai are now holding firmer used residuals, good news used, but manufacturers make money on new cars.

No, it was fitted, by the Dealer as a Hyundai Approved item, this vehicle had done 9 miles when I collected it.
 
Hyundai UK appear to blame poor Dealer installation & an absolute failure of their Technicians/Service personnel to rectify this fault on numerous occasions, during the previous 2 years.
The Dealership appears to have high staff turnover, requiring me to constantly repeat & explain the problems to replacement operatives.

Hyundai are not providing replacement parts, they insist the Dealer "finds the fault".

None of them have been living with such a useless vehicle, I'm just another unhappy customer passing through :whistler:

All those visits, stripping the car of all my equipment, manuals etc. each time, then loading them all back in, losing days at a time, explaining to my customers "I can't make it", for their various requirements. Additional mileage & fuel costs "running around" & "testing" to no fruition.

Email now sent to Hyundai (UK) Service

Thank you for your confirmation email, but your Hyundai Technical have decided NOT to replace any parts.
 
They suggest "a broken wire somewhere"; a faulty installation carried out by the Dealer, prior to purchase.
 
That appears very unprofessional, Hyundai (UK), should be taking a more serious approach and provide any possible replacement parts.
 
Yet another lost week carrying out "tests", and more premature damage to the transmission etc. as it constantly lurches in and out of Limp Home Mode.
 
I am providing you with a link to some of my published "Link Home Mode" comments,
 
 https://www.i30ownersclub.com/forum/index.php?topic=18716.msg255758#new (https://www.i30ownersclub.com/forum/index.php?topic=18716.msg255758#new)
 
Not all events are listed, LHM first manifested in July 2011, I had paid over £600.00 for a return ferry crossing, but the fully laden vehicle was unable to climb the Ships ramp, the vehicle was refused entry as it was considered by the Authorities as unsafe.
We effectively lost our annual holiday.
At the time this was reported to xxxx, at the Dealership who subsequently had the vehicle for 3 days of road tests, the Technicians simply cleared the code and said "Historical".
 
In light of the above, and to avoid anticipated future problems, I request that you also instruct the Dealer to impart me with information so that I can personally disconnect the faulty LHM equipment which may  remain on my vehicle.
 
As previously indicated by the Dealership, please do not suggest I simply call my Breakdown Provider and request low loader transportation to the nearest garage.

Had a 45 minute discussion with a Hyundai (UK) Engineer, the upshot is that the Dealership Technician will be assisted via telephone from Hyundai Technical guiding the Technician to the suspect areas.
Should the fault be undiscovered, then the next step will be to replace the complete wiring loom / or some other mutual agreement with myself / Hyundai.
Much more was discussed, but at present, and in wishing to avoid "a hornets nest", further detail has not been posted.

Andy Smith Hyundai (UK) had requested that I only dealt with "Dennis" at the Dealership, who had now been briefed by them during a long, protracted telephone conversation, to carry out the fault finding/rectification. Dennis subsequently rang me and repeated his & their assurance. Yet another week of further discussion & return visits, (on top of the previous 2 years).

After waiting another month, I returned the vehicle, entered the Service Reception, and asked for Dennis, "he's on holiday until next Tuesday 27th", was the reply, "what do you want us to do this time?"
Dennis had made no attempt to let me know, and this would be yet another wasted, frustrating visit/journey.
I insisted that they rang Andy Smith of Hyundai, and in conjunction with him whilst perusing the incomplete Job Sheets, I went over the previous 2 years of LHM problems, he reiterated that he was shocked by the colossal number of Warranty Claims that the Dealership had back charged, and was astonished that Dennis had failed to be present on my return visit.
The only possible Technical person available was Kevin the Warranty Claims Parts Manager.
For over 18 months I had confined the use of this Diesel vehicle within an radius area of 10 miles from my home, I left the vehicle there, and remain unconvinced that it will ever function correctly again.

They obviously could not ever be bothered to fix it - even with the mighty Hyundai behind them - they all just kept lying and fobbing me off.
Never seen the same person twice.....obviously no loyalty there - they are clearly unable to work as a team.
The Wife is really angry; collecting me & taking me back to the Dealership, each of us losing a days work each time, (on this occasion they have loaned an i20), but she insisted in coming with me, and was hardly surprised when "Dennis" had gone on holiday on this very day, just another fobbing off obstacle.
She voiced her opinion & additional comments in Service Reception............especially when told the replacement loom would take another 3 months, then also off road for several weeks to arrange and replace.
That's if it is indeed the loom, this could be yet another misdiagnosis.

The customer experience is everything, VW owners for example, don't keep going back for more because the cars are cheap, and we all know they are not fault free (or we should know) but the general trend from owners is that inside the Warranty... And to a degree beyond that, the customer gets looked after and feels their ownership experience overall is a good one.

IMO you car is not fit for the purpose it was designed for and should be condemned and replaced, not repaired. Do you have consumer law protection, find out about your rights.

Unfortunately, of all the forum members I think you've had the longest running, most serious problem ever encountered and I wouldn't blame you from walking away from the brand. :'(

Thanks everybody & and now an ordered reply to Phil,

Yesterday I covered the subject of a replacement vehicle with Hyundai (UK) and was told "No chance".

Hyundai (UK) have only recently been involved, they suggest Dealership ineptness/cover up. Next step Korea.

Of course the vehicle is not fit for purpose & is dangerous & unroadworthy, imagine this scenario: at 70mph on a crowded motorway, car suddenly slows to 20mph (depending on the gradient), absolute chaos & a good chance of a very bad accident - now who would be prosecuted, certainly not Hyundai (UK), the Dealer Principal or any of their Technicians. Yes me, with no accident record or endorsements ever.
As you have previously stated this is a Public Access Forum - open to all.

Naturally I agree with your final statement, at present I would never recommend the purchase of a Hyundai vehicle, simply because of the quite dreadful experiences I have had SINCE I purchased it almost 4 years ago, even the Radio emitted smoke, without all the other faults listed on various posts on this site.

Maybe, to spare anymore time wasted at the Dealership, Hyundai themselves kindly completed one for me,

I had this very same last week as well.

I completed a survey  this time last year re my buying experience when i bought my car.

Still waiting for a follow up reply to a comment/question i asked. Said had been referred to hq, presume korea, and would get back.

Since i indicated yes i've had 2 emails from the local new dealership inviting me re service and another re vip special offers car buying event next weekend.

Upon referring this problem to Hyundai (UK), they immediately reacted, contacted the Dealership Service Manager, and arranged the modifications/assistance, and despite his "no show", "seized the mantle", and repeated the technical guidance directly to the Workshop Technician.
A rear dashboard plug c/c connection was suspected, and, I believe, soldered.
I have been pleasantly surprised at their immediate response, it doesn't get much better than that !
The cruise control does not falter or waver, in any gear, fuel consumption has decreased, vehicle runs very smoothly - excellent, seems better than some other owners observations.

Hope it stays this way.

Now, will all the previous repair attempts be backcharged to the Dealer ?

During the past year, all these have been tried. When I have asked which codes were generated, I have been told "only historical", no fault code shown ! They return the car with the ECU "cleared" - as if the fault has been corrected!
This doesn't sound correct to me, it's obvious there has been a fault, so what is the point of recording it, unless it can point you in the correct direction.

Now for the matter of compensation! Should be free servicing for the next 5 years!!
Yes, I've had over 2 years of Hell, (& a useless car), and each time, upon collection of the car being constantly DISMISSED, ie. no discussion or friendly civility, I remember the first time, as it was yesterday; "Historical, reset codes", sign here, your car is parked over there...."

Hmm, that's sad.  :disapp:

Off course it's positive that Hy finally is taking action, but...

Don't you have some kind of consumer protection organisation in UK that can help you regarding legal advice and laws..?

Here we have a law that states that if the same fault is claimed and acknowledged 3 times within the warranty period, you're actually right to claim a new item.

Because of our high taxes on car here in DK there's a special about cars, but that's another story.

I don't know if it's only DK law or if it's EU law, but if EU, it might also apply for you in this case.

I think you've been more patient than can be expected, and I would be ready for the mental hospital if it was me.


I would contact HY UK again and claim a loan car, free of charge of course, until they've found out what's wrong. Tell them that you will not have your car back before they are sure the problem is fixed.
Make sure they have done at least 100 miles in your car before returning it, maybe let the head technician drive the car to work for a period to be absolutely sure the car is ok.

I would also let them know that if they can't do it right this time, you might find it necessary to contact BBC TV (or whatever) to have some progress.

I really hope you get a solution soon.

It seems that Alan Ho's postings about his inability to purchase an i30 in August 2010, with Cruise Control fitted, was so relevant to my problems - which Hy knew Dancar were working on, but did not register with them, or the Sales Teams - who had been advised not to fit them.
When I kept mentioning this to Hy - they kept denying it, but several different Dealership Sales Staff had repeatedly told me this.

Thanks to you both, & to the Clubs assistance & continuous support.

My initial attraction in joining this Club was the enthusiasm for technical interaction, humour, & the underlying friendliness assisted by the common ownership of the brilliant i30.
Subsequently, this was fortunate, as I would not have reached a satisfactory conclusion, ie., discovering the reason for the implementation of Limp Home Mode. Hy (UK) offered no direct assistance or any clues, & had clearly "washed their hands" of the problem; they had become negative & patronising.

These 3 posts are so relevant, yet not so obvious at the time.:-

The inability of Alan Ho to purchase a 2010 i30, with Cruise Control, "suggesting" Technical Issues".

It's so sad to see how incapable the dealers are sometimes to fix these problems. If there's no fault code, it means no fault to them. When they see a fault code, they can only replace a sensor or something, if it didn't help then they start stalling until you get tired of complaining. It should be so simple: if it's not the sensor or whatever lies at the end of wire, then it must be the wire itself.

Having read your post, the cause of my vehicle's problem resulting in LHM is dissimilar, it regularly failed to start, yet never stalled.
However, any fault codes were always  reset by the Dealer with no explanations or code details.
I finally solved the problem using my own Scangauge indicating a known fault code.
I advised Hyundai (UK) & the Dealership, both who had failed, and were in denial for almost 2 years.

I understand you were not stalling.

We have two issues: stalling and limp mode. The two are not necessarily related as I'm beginning to suspect. In fact the stalling began several weeks before the limp mode problem. The limp mode only started when I used CC for the first time. So while my initial thoughts were that the limp mode issue was an escalation of the stalling problem, after reading the beginning and ending of your loooong thread I am wondering if we are suffering from two unrelated problems.
Title: Re: Limp Home Mode
Post by: Mike SX on November 25, 2013, 09:15:43
You probably are; fault finding is a difficult science - you usually look for one problem, but when there are more, confusion shoots in, as issues become clouded.
Failure to start was corrected (after several visits) about 6 months before LHM started.
Was your c/c factory fitted or after market (Dancar Hyundai Approved Accessory) ? An obvious difference is that mine does not require the brake pedal actuated for the c/c to engage; factory fitted does - safety reasons.
Car ran perfectly for several months, until c/c loom voltage fluctuations on the CanBus caused problems - seems most manufacturers use gold plated contacts, whereas the faulty loom did not.

Update August 2014 -  the fourth brake switch has been replaced, and the c/c does now require initial foot brake operation, minimum activation speed, and other operational changes. The fuel consumption has decreased & 63mpg (measured by brimming) was achieved by a recent 1200 mile round motorway trip, all roads driven at the maximum permissible speed :D

I've had a used i30 for a year and now it joined the limp mode club. This happened first time when the temperature dropped from 0*C to -10*C in one night. Limp mode came back every time the revs went up to 3000-4000. I was able to get the car in to the limp mode and connected OBD2 reader to the car. I got the code P0087 (low fuel rail pressure). The code was not saved in to the memory. It was some sort of "present" fault code. But it was not saved in the memory. Also there were no "check engine light" (or any other warning light), only the limp mode. Next time when I started the car I was not able to get any fault codes.

This happened couple of times. I thought that fuel filter might be dirty, so I changed it. Seemed to work for a while. I drove about 1000km and the car went back to limp mode. This time I got the code P1186 (low fuel pressure). I looked possible causes from GDS. It says in there that possible causes are for P1186: rail pressure sensor, rail pressure valve or fuel pressure valve. GDS had the same possible causes for P0087 also. Cause I don't have the multiplexer between PC and car, I had to take the car today to Hyundai service. It will sit there one day before they have time to check the system. They will check the possible fault codes from the car with GDS. I checked the resistance of the rail pressure valve with a multimeter and it seemed to be OK ( around 3.7 Ohms). But all I can do now is to wait and see if the Hyundai mechanics can get some actual data from the fuel sensors.

My car is manual with no cuise control...

Hi

Will be interesting to hear Hyundai's findings.

Just a thought. As you say it helped to change the fuel filter, could the fault be a small leak somewhere to allow air into the fuellines... :question:

If air enters the rail it maybe wouldn't be possible to build up the required pressure.. :question:
Title: Re: Limp Home Mode
Post by: Phil №❶ on October 29, 2014, 16:48:36
I wonder whether you have a fuel problem. In your country I assume winter Diesel is on offer all the time. It can turn to a thick substance if the summer fuel gets too cold. There is also supposed to be a fuel heater near the filter, but not much use if the fuel can't get to the heater from the fuel tank.

Keep us posted.  :undecided:

This is my first diesel, so I haven't got so much experience of diesel car problems. Used to drive old merc for a long time so these new modern cars are way out of my expertise.

We have different diesels for different seasons. In summer they sell summer diesel, in winter they sell winter (or even arctic diesel). I had this diesel in the tank which should work in -10*c. Of course there will be problems if there is any moisture in the fuel system with those temperatures. Moisture in the fuel system and cold itemperatures are a common problem here with diesel cars. Therefore I changed the filter. Last time when the car went to limp mode I had a full tank of winter diesel.. That works in -25*C temperatures and it was only +4*C so the temperature should not be the problem.

A leak was also in my mind. I looked all the fuel lines under the hood and they seemed to be dry (from the outside). So atleast no diesel was coming out of any high pressure system. Or then I just did not see it. If there were an air leak, shouldn't it be somewhere before the high pressure pump? Cause the pressure is so high in common rail, in my opinion the fuel should come out, not the air go in. But if there were a bad seal or connector before the high pressure pump I guess that pump could create a vacuum in the fuel lines which would suck air in. But I quess anything is possible with these modern day magic motors. My best quess based on the measurements I made and the data from GDS that the problem is the rail pressure sensor or the fuel pressure valve. But I will let you know the results, what ever they are. Hopefully this will help some other unlucky i30 owner with similar problems.

Title: Re: Limp Home Mode
Post by: sundiz on October 30, 2014, 12:28:30
I must say I got pretty good service from the local Hyundai dealer. Never got this fast service with my old merc. They were supposed to check the car tomorrow at noon, but they called today at 9 am that the car is ready to be picked up. Unfortunately they were not able to get the car in limp mode. They drove 30km with analyser connected to the car, but nothing happened. Car worked fine.

Based on the information I gave about the fault codes P0087 and P1186 they ran some tests to the fuel pressure sensors and pressure valves. Everything worked as intended. They were not able to find a real cause for the limp modes.

One mechanic had told to service manager that there had been one car with similar problems some time ago. Random limp mode and no fault codes... They were able to fix the problem with new fuel filter. They did not change it to my car because I had changed it myself just over a week ago. They told that I might have fixed the problem with new filter and the last limp mode was just some sort of odd bug in the system. But difficult to say what was the real problem without any evidence. They recommended that I'll go and buy some fuel system cleaner and add that to the fuel tank. I asked if they could do that for me, and they did. Now I have Forte fuel system cleaner in the tank and we will see if that helps. Service manager told that with some brands like Skoda, Forte treatments are done as a part of normal service of the car and those treatments are recommended by the manufacturer (Skoda).

If the limp mode comes back, I might change the filter once more, if I can't get any other fault codes out of the car. I used genuine Huyndai part last time, because I red from somewhere that aftermarket filters have caused some issues in someones car. If there is some dirt in the tank that plugs the filter, changing the filter might help to clean up the system... or not. But I'll hope that the current filter and Forte treatment will help. Here, because of winter, it is  recommended in general that diesel fuel filters are changed every fall before temperatures go below 0*C.

The Forte treatment was 20€, checking the system and sensors was 100€. 120€ bill was not too bad. With merc service they usually charged that for just walking in to the shop  :D
Title: Re: Limp Home Mode
Post by: Phil №❶ on October 30, 2014, 17:22:44
I hope it's fixed. If you're unlucky to have it occur again, record the temperature outside the car for reference. They may not have been able to reproduce the fault because the temp was warmer when they tested.

Not sure of your mechanical abilities, but if there is some dirt or foreign material in the tank, replacing the filter won't fix your problem. The best way is to fully drain & clean the tank and flush the fuel lines completely, otherwise you will just keep replacing filters until they block again and that is expensive and very inconvenient, long term.

Well, today the temperature went below zero again. Car went in to the limp mode again. I guess this is going to be a long battle... I got the code P1186 again. I guess I have to wait until the temperatures drop and take the car to service again. Last winter the car worked fine...

You said you had checked the resistance in the fuel pressure sensor.

Is it just a 2-pin connector.. :question:

What if you disconnect the sensor and connect the pin 1 & pin 2 so the ECU allways get the low resistance. Try driving with that for a period..

I checked the resistance of rail pressure valve. That has only 2 pin connector and the resistance should be 3.42-3.78 Ohm according to GDS. That valve is on the left side of the common rail when you stand in front of the car and look under the hood.

The rail pressure sensor is on the right side of the common rail. The pressure sensor has 3-pins. The GDS says that the sensor should give under 1.7V when motor on idle (fuel pressure 220-320bar and approx 4.5V when full pressure in the common rail (1600bar). I just dont know what pins I should measure to check those values. I think it needs some sort of adapter if you want to measure those voltages when car is running and sensor is connected, because there is no contact where you could connect your multimeter when the sensor is connected to the wire. Seems like I have to spend tomorrow under the hood. There is also fuel pressure regulator valve in front of the motor that I could check. That should have resistance of 2.6-3.15Ohm.

Car worked fine when I came back home. I've started hoping that something would actually break down so it would be easier to fix. This random limp mode thing is really annoying.

I spend some quality time with my car at the garage. I opened every sensor or valve plug I was able to see in the fuel line system and cleaned up the contacts with electronics cleaning spray and compressed air. I also re-measured the rail pressure valve. The valve is on the left side (black circle) and the rail pressure sensor on the right (yellow circle).

(http://i243.photobucket.com/albums/ff56/sundiz85/markedmotor.jpg)

The pressure valve seemed to be ok.

(http://i243.photobucket.com/albums/ff56/sundiz85/IMG_20141101_102658.jpg)

One trick for people who are not into electronics: When measuring these really small resistances (couple of ohms) the wires of the multimeter affect to the reading. It shows now that the resistance is 4.2 Ohms. That is out of the specs (3.42-3.78 ohms). With my cheap multimeter the resistance is about 0.5 Ohms when the tips are connected together, nothing between them. So you need to count 4.2-0.5=3.7Ohms. That value is ok. With larger resistances the test wires don't play so big part and can be ignored.

The pics in the GDS aren't very good. I was looking for the fuel pressure valve and I am not sure if I found the right connector. I measured the resistance from this pin and I was around 3 Ohms. That would fall in the spec of the fuel pressure valve (2.6-3.15Ohms). I', just not sure if that was the right connector.

(http://i243.photobucket.com/albums/ff56/sundiz85/markedsensor.jpg)

I also checked the fuel (pump?) fuse, that was ok. Then i moved some other fuses to make sure they get good contact. At last I was going to check the fuel (pump?) relay, but it was really stuck. I had to help it with screw driver just to get it moving. I was almost out and just before it would have come off the relay crumbled into my hands. No sure if it was crappy relay or am I just too strong, but the relay broke down. Lucky for me most of the relays are similar so I took the relay from the horn and used that to replace the fuel (pump?)relay.

I did a small test drive and the car worked fine. There was +1*C so the temp. might have helped. Guess I'll see what happens when it gets cold again.

I'll have to go buy couple of relays next week, because the car is not so horny anymore...

Oh man. I just remembered on thing when writing all this stuff about the "fixes" and temperatures. I got some freeze spray in the garage. I guess I could spray that to fuel valves and sensors to see if I could get the car back to limp mode. Maybe tomorrow...
Title: Re: Limp Home Mode
Post by: Phil №❶ on November 01, 2014, 17:27:13
Just wait for the temp to drop naturally. You won't be able to simulate what's happening just with freeze spray as the "problem" may be in the fuel line from the tank to the engine. At least you've checked all you can for now.

Thanks for the pics & tips. :goodjob2:

Car worked fine couple of days. Today when I left work limp mode came back. Got the code P1186 again... I don't think the temperature has anything to do with the limp modes. It was +8*C today, so no frozen water in the system.

I've started to browse some kia forums also, because they might be little more popuiar cars and there are quite a lot of same parts in ceed and i30. I found some russian kia forum and it looks like someone was able to fix this kind of problem by cleaning the fuel pressure valve. Or at least it looked like that when I used google translate  :D Or what ever the thing is on the top of the high pressure pump. Looks like it's connected with 3 hexagon or torx bolts. Same valve/sensor than in the last pic I posted. Has anyone opened that sensor/valve? I would like to check that if its dirty, but I was just wondering if that can be done by "amateurs". Is there some high fuel pressure that is going to spray some diesel around the garage if I start opening those bolts. Or can that thing even be taken out without taking the highpressure pump out before?

That is possible. I saw one topic at some kia forum where a sorento suffered from identical problems. That was fixed by changing the high pressure pump. But I hope it is something else (cheaper). That pump probably costs a fortune + labour and my car is out of warranty. My car has "only" 76 000km and if high pressure fuel pump doesn't last longer than that I would be really disappointed to the quality of the Hyundai.

That pressure sensor should NEVER get dirty as the fuel has been filtered prior to reaching that section of the car. BUT, thee is an inherent design fault in common rail Diesel's in that there is no further filtering after the initial fuel filter. This means that should any portion of the high pressure pump or other components fail, their bits could pass through the pump & injectors which would be the only way your sensor could get dirty.

Personally, I wouldn't touch it and as you seem to continually get an error, why not just replace the whole sensor. It could be inspected at disposal to see if any foreign material was causing the problem, too.

As far as the temperature, well we can now rule that one out.

Car worked OK today. I sent yesterday an email to other local dealer service experts and asked their opinion what should I do and do they have any other ideas. They said there have been some minor issues with the fuel filter assemblies: small leaks, small fracture in the heating element wich sucked air in etc. The filter assembly could be the problem, but there might be also many other possible causes. New filter assembly with new sensors would be the "cheapest" thing to replace. That whole assembly would cost around 270€. If the problem is in high pressure fuel pump or in the injectors, then it would cost a fortune to fix the problem...

It got a lot better when  changed the filter. In my opinion there was a small amount of water in the water separator when I removed the old filter. The temp did drop to -10*C the night before the first limp mode so if there were some water, that should have been frozen. In physical point of view, water expands when it freezes. Therefore the expanding ice might have damaged the filter and the filter assembly. Does this make sense to anyone else, or am I just making things up while trying to figure what the hell is wrong with my car?

I guess I'll order the new filter assembly...

And if that does not help, I saw one slightly wrecked i30 nearby with a 3000€ price tag  :D. It would probably be cheaper to buy that and replace parts one by one until my car stars working and then sell the wrecked on to someone else. But with my luck I would just end up having two non-working i30s  :D

It's a driving nightmare, I hope you soon discover the problem(s).
Attempting different remedies can seem non exhaustive; unless you soon discover the LHM cause, you will discover an alarming number of LHM reasons, and may unfortunately never quite trust the vehicle again.
However, although Hyundai are not alone in LHM problems; specialist rectification knowledge is scant.
Keep us all posted  :)

I haven't re-read those links I posted but it wasn't the injectors that fixed the problem, think it was the fuel filter assembly ( a hairline crack is certainly a possibility I would imagine) :undecided:

The water issue is something that need immediate attention, so much so, that Hy put a warning light on your dash for that very reason. How sure are you that there was water. Before ordering expensive replacements, you should spend some money having your tank drained and the fuel lines / filter purged and then refill with good diesel. It may save you doing any other expensive repairs to your vehicle. You should also avoid the service station that sold you contaminated fuel. A fuel additive should also be used, to protect you from all these problems in the future.

If water gets past the filter and into the high pressure pump and then into injectors, the injectors can be blown to bits internally, as the water turns to steam, with injector debris passing through your engine, causing engine and HP fuel pump destruction, a very expensive repair.
Title: Re: Limp Home Mode
Post by: sundiz on November 06, 2014, 12:30:26
I am 80% sure there were few drops of water. But I mean that there were literally only few drops, not gallons of water. When I emptied the fuel filter to a container I saw few drops that did not mix with the rest of the fluid. Just like oil and water do not mix. But the amout was really small. But I guess that is enough to plug the fuel line. That and dirty filter could easily do the trick. The water warning light has never turned on during a drive.

Honestly I would have been suprised not to see couple of drops of water. Thats why there is a water separator. Usually the problem is not the bad fuel in here. Of course that happens, but the quality of the fuels is good in here generally speaking. Biggest problem is the condensation. In the fall time it usually rains a lot and the air is humid. The temperature variation during a day start to increase more and more when going towards the winter. If you have empty tank the moisture in the air condensates inside the tank. Especially when going near freezing point. I keep my tank usually full, but I have been driving quite a lot in the past few monts so the tank has not been always full. I drive my car 5-7 days in a week and keep it in a warm garage most of the nights which increases the possibility of a condensating water.

I have the old filter in the garage and I think I'm going to pop that baby open to see how contaminated that is on the inside.

I ordered the new filter assembly today. I was hoping to get it tomorrow so I could change it during the weekend. But I quess those parts are not so commonly needed, so they might have to order them abroad.
Title: Re: Limp Home Mode
Post by: Phil №❶ on November 06, 2014, 15:26:52
Condensation is a serious consideration for all pilots, part of the pre-flight checks. If it is for them, it should be for all fuel injected car owners. When I first joined I started a thread about this, but the reaction was only warm to say the least. IMO, all Diesel vehicles regardless of brand should be fitted with dryer crystals in the fuel vent line which admits replacement air as the fuel is used. The crystals are cheap to buy and no matter how much moisture there is, your tank would remain dry. I strongly suggest that you use a Diesel additive which can deal with water, not only to eliminate it, but if allowed to remain in the tank, you run the risk of breeding Diesel bug which is a living fungus. It only lives on the Diesel water layer of your fuel but if left unchecked, eventually wreaks havoc with your fuel system.

Many owner's here do not use it and have never had a problem, a few have. I use it on our Diesel's as insurance against, water and the bug. It seems the bug is more prevalent here in Oz. It is an airborne problem and to be avoided like the plague. There should be a similar product in your country.

For your info, here's a link to the product I use, I have no affiliation at all with this company.

Diesel additives are likely to get someones attention  :D. Others say they are good, others say the destroy your engine... Personally I believe some are good and some aren't. I have now the "cleaning" additive in the tank. When the tank gets empty, I'll add some water removal. I would not like to mix two additive. Never know how they would act together.

I'll get an endoscope in couple of weeks. I'll have to check if it can handle chemicals (diesel) or not. If it does I'll take a look inside the tank to see if theres something that does not belong there.

Today I was finally able to go work in the garage. I got the new filter assembly (part 31911D) couple of days ago. New filter and new sensors and heaters etc. were allready assembled. 272€ from this was still quite over priced in my opinion...

(http://i243.photobucket.com/albums/ff56/sundiz85/IMG_20141115_103639.jpg)

I changed the filter couple of weeks ago, so this was quick and easy job. And now didn't even have to remove the filter from the assembly. Took only about 30min. Here's old vs new.

(http://i243.photobucket.com/albums/ff56/sundiz85/IMG_20141115_112839.jpg)

Bleeded the system and there it sits. Cleanest part in my car  :D

(http://i243.photobucket.com/albums/ff56/sundiz85/IMG_20141115_114031.jpg)

Started engine and no leaks or warning lights so everything is OK, for now. I did a 20km test run and everything worked well. Now I gotta keep fingers crossed and hope that the limp mode does not come back.

Little bit of offtopic:

I must say that Hyundai parts are not the cheapest ones around. When I picked up the parts from local Hyundai dealer I asked if they had those micro relays for horn (and fuel pump etc.) I broke before. They didn't have them right now, but they could have ordered one for me. When I heard the price,  I started laughing. So did the salesperson. They would charge 40€ from a 4-pin micro relay with a Hyundai logo on it. Never thought they had such a ridiculous prices... Only thing with the relays is that the Hyundai relays are about 1mm smaller than "universal" micro relays. And in the fuse box there are these plastic "covers" to prevent using normal sized relays. So I used dremel to grind plastic relay "covers" in the fuse box and fitted normal universal relay. That relay costed only 2.9€. Now I have a working horn again. Gotta love Hyundai pricing...

Here on the left is the original, which should be solid gold based on the price tag. On the right is the 2.9€ relay which works as well as the original.

Here again... unfortunately.

Car worked fine until now. It was time to make small service for the car before the winter. I changed the fuel filter and did not use oem part. It was manufactured by AMC if I remember correctly. The car worked fine, but in the last week I had to crank it few seconds longer before it started and the acceleration was little bit jumpy couple of times. I drove about 1000km with the ACM filter. Today the car went to the limp mode in the morning traffic. No check engine light, only powerloss. I restarted the car in the next red lights and drove to work without any problems. Strangely I was able to read the codes in the parking lot even I had restarted the car. That did not happen previously. I got two P1186 codes, so it was again about the low fuel rail pressure...

Went to the dealer after work and got overpriced OEM fuel filter. I got just back from the garage & test drive. It seemed to work, but I think next couple of weeks will tell the truth. I am starting to get some regrets for buying this car...

Sad that you feel this way, as you may have read, my i30 gave LHM problems for over 2 years, but during that time I still really liked the car, and there is the rub; you may have to make that final decision, please don't ignore alternative manufacturers problems (that are so well publised) 😉

I assume that if the low fuel rail pressure was cured, you would be much happier with the car. Why not get it seen to professionally instead of trying to take short cuts with non oem parts.

It is unfair to blame the car if the ACM filter is the cause as YOU supplied the part. Also be aware that there just may be a small air leak into the system caused by the actual filter canister. I would look to replace that as well, just to be on the safe side.

When I previously had limp mode issues and I took the car to the dealer, they did not know what caused them. They weren't even able to get the error codes out of the car. I had a discussion with them and we thought together what might be the issuel. Therefore I am not paying to the "professionals" about something that I can do by myself.

I don't know about your country but here getting OEM parts for hyundai in here is not the easiest thing. Especially if you need them ASAP. One time I had to wait 4 days to get fuel filter from the local HY dealer... Third party parts are available much more easily and you can get them from almost every spare parts store. It looks like I have to order larger amount of filters and other normal service parts from Korea so that I would have a small stock of OEM parts in the garage.

I knew there might be a small risk with non OEM filter based on what I have read about these problems. I did not expect it to be this bad (if that was the cause). I've heard and have had issues with bad filters, broken filter assemblies, leaking fuel lines etc... In my opinion the fuel system is just badly engineered if there are so many (and fairly common) problems. I never had any issues with non OEM parts with other cars I've serviced (even in a Hyundai Getz).

I checked all the fuel line connectors and they seemed to be in fairly good condition. I think there has been couple cases in this forum where the quick connectors have been leaking and letting air in to the fuel system. I wonder why they have used those quick connectors in the fuel line. They seem to be little flimsy in general. Just a normal hose with a normal hose clamp would have been much more cheaper and much more reliable solution.

Time will tell if the problem is solved. If the limp mode does not occur in the next year or so, then we can blame the non OEM filter.

To be fair, there are also good mechanics. I understand that it is difficult to fix something if you can't see the symptons or get actual fault code. Also you rarely actually fix something in these modern cars. There are electronics and other stuff in the parts which makes them hard to fix. It is easier to replace the whole part, which gets expensive...

Just a quick update. It has been almost one month since I installed the OEM fuel filter. Car has worked flawlessy since that.

I still had the original  OEM fuel filter in the garage from the time I had limp modes first time. Finally got some motivation to check it with endoscope. There were some small black crap inside the filter. Har to tell if it was from fuel or was it just dust from the air. The old filter was on the floor all this time... The most recent filter (non OEM) was clean from the inside, so it seems that the actual filter material was the cause for surging acceleration and limp modes.

Finally got some motivation to check it with endoscope. There were some small black crap inside the filter.

I got checked with one of those once.   :neutral:

I know people whos "food route" has been checked with one of those. According to them "input" checks were worse than "output". Said to be one of the most unpleasent things when you need to swallow the tubes...

I actually had no problem in the private system as I was properly sedated at the time.
I do know people, however, who had it done in the public hospital system in Australia and it was less than pleasant due to to skimping on the required drugs.
My specialist told me to only ever have it done within the private health care system (in Australia).

Hi Mike, im experiencing the exact symptoms that you had. Mine is a 1.4 petrol 2014, Just wanted to know did replacing the wiring loom resolve the issue at the end? Was that the main fault?

No problems since the loom was replaced.
It was the only problem causing Limp Home Mode.

With the codes logged, it should be a simple fix....
My long term (finally solved) problems were created not only by the selling Main Dealer incorrectly fitting a cruise control unit to my model, but by their continual ineptness.

Hi Mike,

I had an issue with a fuse that serviced the camshaft position sensor.

The check engine light/limp mode would cone on and off periodically but under no specific circumstances. It may be worth checking all your fuses under the bonnet, particularly anything that services the powertrain.
