As stated in my post above (<link> (https://www.i30ownersclub.com/forum/index.php/topic,3007.msg72651.html#msg72651)), my wives car has being having the smoke issue, took car to Hyundai for 45k service, i mentioned the smoke issue, they said they would look into it. When picking up car i asked about the smoke problem went, & they replied they tested the glow plugs & they had too much resistance, they have ordered new parts, & i'm wating for them to call for fitment, all under warranty. Let you guys know if this fixes the problem, once fitted.
Cheers Bloodnut

Nic (Opa_1) had this issue on his CRDi in Oz and it was the glow plug shorting out (not working properly therefore) It was fixed under warranty and fine now (he might come on the comment further when he has access to the net (Is down in tassie in a "blackspot" at the moment) :mrgreen:

thanks for the comments guys,re glow plugs first cold start of the day is ok,what with wrong service book and now this not happy with hyundai ownership

Jeepers.. I Hope nothing major goes wrong..Don't mean to be rude but they are fairly minor problems .. check out a few Ford or VW forums and I think you will feel better about Hyundai... :P
-
yer... try owning a holden...

at dazzler,i have come out of a ford and no probs,im just aliule disappointed

I just ask that you keep an open mind as I am sure in the long run you will find Hyundai ownership a good experience (as the majority on here have) .. :cool:
I have only had 3 Hyundais out of 26 cars but I would say in hindsight the Getz and i30 were extremely positive ownership experiences.. :cool:
-
what was the other one dazzler? and how did it rate?

what was the other one dazzler? and how did it rate?
It was a 2002 Hyundai Elantra I only had for about 3 or 4 months as a fill in vehicle.. Looked the part but I don't think it had been well maintained as it had a few silly cosmetic faults although the drivetrain was pretty sound... :cool:
It was a very tidy looking vehicle with full body kit and 17" alloys but had probs with Wipers, Washer Bottle and lots of other stupid stuff...

Car booked in this friday, dealer thinks injectors or glow plugs, will keep you posted.
-
I had a Hyundai Tiburon(Coupe version) from 1997 to 2004 and did 250,000km before selling it to my brother-in-law who still drives it around. It was such a reliable car and the reason why I went back to Hyundai with an i30. My sister had the Accent and my mother has a Getz both were/are very happy with them. Extremely reliable cars. Maybe yours is just experiencing some teething problems once they sort that out you will most likely have care free driving. Its a bit like the bath tub curve, once the initial problems sorted out very few after that.
-
Just had a call from Hyundai Uk customer services, they say not a known problem, he asked how many miles car has done, i advised, he thought DPF was regenerating, I advised car does not have one, he then said he not technical, arse from elbow springs to mind.
-
The i30 DPF does not regenerate on its own anyway. FFS thats a poor response from them.
-
ok car back from dealer, they witnessed prob which is not right, glow plugs,injectors all ok, they want car for one week and take to derv expert, if they still cannot fix hyundai uk to look at car, if prob still there i will reject car,
-
Hopefully an expert will find the cause.
I guess they will have checked the fuel filer for water.

i some how doubt it,kia have accepted the problem but comfirm no fix,they have 3 chances to fix mine,failing that car will be rejected,which is a shame,as its a good car.

:eek:yer i got that problem too so dose my perents i30 they got puffs of white smoke in the morning after using bio diesel since then we stoped and still smoking for 2secs then ok
with mine i never used bio but i got lots lots lots of white puffs of smoke (3-5sec) in the moring after i tanked up with BP ultimate Diesel iam sticking to normal diesel and thats it
i allways wait for glows to turn off (not too long coz then they burn out) :wink:
and i idle it at the end for 5-15sec on average :D
-
oh oh i for got to say when my i30 puffs out a lot of white smoke in the morning more then any other day i notcied my rev counter doing little jumps like 700 to 800 down to 700 to 800 it does about 3 - 4 little jumps then stops at 700 and no smoke when it stops
this only happens on cold motor so i dont know what the problem is
other then that im really happy of my little i30 i called it duck lol :D :D :lol:
im happy i got a i30 not a mitsubishi triton they are
***********PROBLEMS TRITON*****************
father in-law has a 08 triton glx-r model and so many problems
1. accelerator sensor stuffed up = new sensor + wiring
2. knock in motor = replaced motor
3. oil leak 3 times gearbox = new gaskets
4. oil leak gearbox 4th time = new gearbox after making sounds over 80km/h
5. very little ground clearance 205mm therefor drive shaft some how bent while 4wding = replaced
6 .turbo shut off ok max power motor wont start after = new turbo
7. lucky he had warranty :lol: :D :lol: :D :lol:

The glow plugs switch off automatically.

my boss has an 08 triton glx-r... its a heap of rubbish... last week it was running like a dog... apparently the computer "lost its programming" they had to replace most of the sensors, and are awaiting an AFM, and intake plenum... it was also shifting (auto) like it had a full shift kitted auto in it (banging hard into gear)
he hates it and what makes it worse for him, is it has lots of rattles/creaks and mitsubishi dont cover them in the warranty (so he says)
-
Sounds like they should rename them Triton RS (over her RS stands for Rat Sh1t)
..mind you that didn't stop Subaru calling one of their impreza models an RS :wink:
-
Had one instance of smoke and rough idle for a couple of seconds. My problem was not waiting until the heater coil light to go out.

Glow plugs replaced by dealer, but still got same problem, car goes in again next week, if they fail to fix, car will be rejected.

Sorry you are having issues with this particular problem. Your dealer should have sorted this by now one would expect.. :mad:
I had the same issue at cold start and it is embarrassing to have a nice brand new car driving of in a cloud of smoke! :-[ Testing revealed the glow plug fuse had failed on my car and this was replaced fixing the problem. However it reoccurred and second time they found the the fuse was ailing due a short at one of the plugs. Has you dealer replaced the fuse? Expect it is a problem beyond this but still worth asking. Hope it gets sorted soon. Cheers :)
-
I always forget I've got glow plugs and start the engine straight away!
however it starts fine,
on the odd occasion i do see a little smoke but goes straight away.
But i have noticed the glowplug light goes off very quickly anyway!
-
I always forget I've got glow plugs and start the engine straight away!
however it starts fine,
It'll smoke more when the temperature outside drops, if you don't allow the plugs to work for a couple of seconds.
-
Just to let you all know if the 80amp fuse inside the fuse holder under the bonnet WILL cause the I30 to run rough and blow smoke on first start up BECAUSE the glow plugs have not glowed even if the light on the dash has gone out! this is a easy fix!!! all is needed to fix is remove engine cover and look behind the motor and towards the back for the glowplugs, here you will find the plate that is connected to the rear plug is touching the engine block which in turn blows the fuse. I believe this happens because the plate bends with heat over time. Replace fuse and your good to go!!!!
Cheers
PS should take 1/2 hr to fix
-
Thanks for that mooglen, it's good to know what causes the fuse to blow as there have been a few reports of it happening. I guess in those situations if the dealer didn't know about the shorting it's just going to happen again sooner or later.
Did you eperience this fault yourself?
.....and welcome to i30oc :exclaim:
-
Welcome Mooglen..
Are you a Hyundai Technician..?
-
I notice from other forums, that owners have had fuse replaced/checked out OK & still have same problem.
-
Could you (with the help of the pic. below) locate the thing you were talking about.
Just say in which area..1., 2. or 3.? Thanks

Could you (with the help of the pic. below) locate the thing you were talking about.
Below 1 and not as far back as 3.
Stand in front of the car and lean over the (switched off!) engine. You don't need to take the plastic cover off (at least on the U2) to see the wiring and the first glowplug.
You can only see one of the glowplugs as the other three are (presumably) under a heatshield to the right of it there. I've just tried to take a picture of the one showing but its hard to get the camera in there (and its dark). If you lean over the engine you can see down a hole into the heatshield to see the one plug, and its easy to imagine where it might ground on the shield.
On mine the wiring to the first plug says "GLOPLUG" in big writing :mrgreen:
-
Some of the pics came out ok:
Relay box showing 80A Fuse and 70A Relay. (Think they got that the wrong way around, the fuse should protect the relay!) The fuse has a small lense on the top so can be visually inspected without the need for removal or a multimeter.
(http://www.bug-byte.co.uk/i30/glow1.JPG)
I'm kinda suprised at the ratings, as GSW indicates 4 glowplugs could draw as much as 100A. Probably out of date info.
This one shows the wiring connector that goes to the glow plugs. I'm still sure there is 4 there, even though its only the first one thats visible.
(http://www.bug-byte.co.uk/i30/glow2.JPG)
And finlly the only pic that came out of the plug itself. You can see where the heatshield could potentially cause an accidental earth to the plug. I'm sure water here would cause a prioblem, but the proximity to exhaust and DPF would sort that.
(http://www.bug-byte.co.uk/i30/glow3.JPG)
Keep in mind this is a U2, so if anyone has a U variant things will look a little different.

It looks like the number of CRDI owners with glowplug issue is increasing...
Month or so ago I noticed that car (i30CW 1.6CRDI, BlueDrive) emits a lot of smoke on startup in the morning (-5C at night). Booked it in for a check. First time they didn't find anything. Next time I left it overnight at the service for the engine to cool down. They found out that two glow plugs has burned out. Now waiting for replacement plugs to arrive.
Now the fun part. The guy at the service said that glow plugs aren't covered by warranty. Well, I'm not going to pay for them. The car has only 15000km, so it's definitely not a normal wear. My parents' Mazda had original glow plugs after 25 years and 500 000km. And it started in -25C just fine...
Ah, BTW, can anybody advice where I can find original warranty text? I want to find out what is covered by it and what is not. Service book in my car is from older model.
-
They are not specifically mentioned in the UK warranty statement. My guess would be a dealer would replace them under warranty in the first year, and anything after that would argue they are a wear and tear item.
I'd counter-argue if they are subject to wear and tear why are they not included in the service schedule. Could be tricky.
The glowplugs would definitely get used more in colder climates. According to the tech specs at -10c they should stay on for 16 seconds. I've never seen it on for more than a few seconds.
-
Dealer has checked my fuse & all ok, but car still smokes
-
Do you know if they checked the relay too? They would need to take it out and check with a meter

They would need to check the resistance of each plug too. Gsw has a detailed fault finding procedure with pictures for potential glow plug faults

ok car been at dealer last 2 days,they have experienced fault,but it got them beat,they did not want to send to derv expert as if no fault found hyundai no pay,so im having to initially pay to get things moving and might get reimbursed depending on what they find,not good on a 60 reg car in manu warranty,i will advise them the above

Dealer has checked my fuse & all ok, but car still smokes
This issue is becoming quite frustrating! :mad:
I have to be very happy that it was solved for me with just two trips to the dealer. Both times I left the car overnight so they could diagnose with a morning start. As I mentioned the first time they found the fuse to be faulty and by replacing this the problem was fixed, however it was not long before it reoccurred!
The fuse had failed again indicating there was a further issue and as it turned out it was one of the glow plugs shorting on the cylinder head. Lorian's picture of the 'Potential problem' probably shows best how this may happen.
As the smoke is essentially the result of unburnt fuel being forced out of the exhaust this, to me, indicates the glow plugs are not heating correctly. If the plugs have been replaced, which I understand has been the case in your car, this would eliminate these leaving the fuse or the relay as these are the gateway to providing power to the glows plugs allowing them to function.
Taking Lorian's suggestion I would definitely have the dealer test and verify the 'Relay' as well as the resistance across the plugs! Hope this is solved for you soon :)
-
If they continue to have problems diagnosing you might nudge them towards
GSW -> Shop Manual ->20xx -> D 1.6 U2 -> Engine Electrical System -> Preheating System -> Repair Procedure
Although one hopes they know about the documentation and have done the three sets of tests. (plugs, fuse and relay).
If they relay is faulty then the ECU should detect it and record a fault P0670
If one/more plugs fail short circuit the fuse should blow. Failing open might get un-noticed by the ECU I think.
Keep in mind I'm not an expert.

Gee m8 I'd be peeved.. I understand the position the dealer is in but I don't recall that ever happening in Oz where you have to pay upfront pending a ruling by the manufacturer :rolleyes: ( this obviously a car fault not a user fault) :eek:
-
and as it turned out it was one of the glow plugs shorting on the cylinder head. Lorian's picture of the 'Potential problem' probably shows best how this may happen.
I think the end of the heatshield from the DPF is closer than the head and the most likely thing to touch. If that's the case this could be something most specific to UK/european cars produced since July 2009 (U2s). This is pure conjecture of course.
-
It just gets better, G/F had good converstion with dealer principle, who said smoke to be expected because of choke, g/f knew this was BS as she had old d reg uno which had a choke, g/f said loan car must be faulty then as no smoke, dealer p went quiet, service manager called to confirm car gone to expert so they can have a good look at it, but also said he would advise dealer p that diesel's dont have chokes, g/f rightly said he not in a position to make comments about stuff he does not understand, dealer p also said when he personally started car all was ok which when it warm all is OK, but service manager confirms he has seen the fault, talk about poor communication.
Roll on tuesday for the report.
-
This is a shame Sooty :'(
Stupid things like this that happening to you take the edge off what is a really exceptional car for this class... :cool:
-
good converstion with dealer principle,
Where should we steer clear of if we want warranty issue sorted?
-
When this saga is over, I will name & shame the dealer.
-
I think when I take my car to be serviced next month I'm going to have to stay and watch :exclaim:
Here is the principle, and his choke

Is there some kind of heating device in the inlet manifold, car a derv expert, but the bloody this has not smoked, not the cold, but car has smoked for us on more than one occassion when it has been at this temp.
-
I think I understood what that meant. It's pretty chilly today, I'd have thought it would have smoked for sure when the engine was cold if the glowplugs weren't working.
I can sense your frustration as you typed, not quite sure what you meant about the heating device, the glowplugs are the heating devices.
-
Pre heat system (glow plugs) all OK, derv expert spoken to hyundai who mentioned inlet manifold pre heat system, i cannot believe my luck, when it colder the 8 degrees, car would always smoke, all of a sudden, UK weather warm for time of year (over 8 degrees) but even so, car would some times smoke, but nothing now.
-
It's only about 6 or 7c here at the moment, and feels colder.
I'll be interested to hear about the manifold pre-heat system, as the only pre-heating system I can see in their documentation are the glow-plugs.
-
New one on me and I've had mine for 3 years without smoke!!!!
-
Ok, diesel expert, has said there is a pre heat system of some kind in the throttle pot, by the inlet manifold, there is no live feed, they need to know more about this, to move forward, dealer is slow to respond.
-
Update, have spoken to derv expert, they have not had the information they require from the dealer, so they cannot progress, they did experience some smoke but not enough to worry about which is just my luck, they have documented in report dealer did not provide information.
So a meeting with the dealer beckons.
-
The only other heating element I can see associated with the fuel supply is a small pre-heater on the fuel filter casing, but thats not on the inlet manifold. Maybe its a fuel temperature sensor issue.
Lets hope the dealer can find the info they need quickly, or if not, it might be worth dropping an email to Hyundai customer care, if you haven't done so already.
-
As all hyundai dealers are franchised, it appears Hyundai uk have very little clout, inovice for diag is £65+vat, if I have to pay I will, but will claim back for small claims, also going to speak to solicitor, who believes we got a very strong case to reject car/exchange.
-
That's not unusual, most dealers for any make of car are franchises or independants. I think maybe Ford own a dealership (at least they did), but I don't think many do. Shouldn't stop them getting the info they need.
Its disappointing you have not found satisfaction. Please keep us posted.
-
Update, rejection letter sent to dealer, also contacted SMMT
-
Update
recieved letter from dealer who wont accept rejection, the service manager has emailed me confirming the car is putting out to much smoke ,but here is a snip it from the letter "darren service manager did say that on idle it was putting out more smoke than he would have expected,however he is not a fully trained vechicle technician"
I had a meeting with the MD & mentioned the comments made by his Service Manager who has 8 years experience working at said garage, and that he should be more than qualified to confirm such a problem, but MD dismissed his comments (also stated in his letter to me not accepting rejection of car) stating the service manager is not a fully trained technician, and therefore is not qualified to make these comments, but on many a previous occasion the service manager is happy to give out technical advise to me. In my opinion you do not need to be technically qualified to determine there is a fault with my car, due to the amount of smoke produced, anyone can see there is a problem.
So the car has been to the dealer 3 times to attempt to fix the problem & a diesel expert, and it has got all concerned beat, maybe there is a manufacturing defect, the glow plugs have been changed, and while I admit there are no broken parts, the car continues to produce too much smoke which has been witnessed by the service manager at the dealer.
As a goodwill gesture, MD has offered a red pre registered car, meaning I would not be the first owner, I declined for this reason & its plain red (my car is metallic blue, so I would be losing out financially) MD then said he would try and source a pre registered car in the colour of my choice, again the offer was declined.
I have now requested that Hyundai Technical view the car & the video evidence collected, if they agree car does produce to much smoke, I will contact my solicitor.
-
Is it possible to make a short video of exhaust while starting?
Don't worry if you can't I don't think it will help, just curious to see what it looks like.
-
Smoking hyundai i30 crdi at strtup (http://www.youtube.com/watch?v=0Y4bsX0Wj_g#)
This video was taken prior to glow plug change, every cold start would produce this much smoke, now plugs changed this problem occurs say every 3-4 days, but when it went to derv expert car behaved.
In between the 3-4 days, you start car there is instant white smoke & diesel smell & then it starts to produce more white smoke, however as its now v cold this is masked by condensation.
-
I had an old banger many many years ago and it smoked really bad.
Turned out to be a combination of the rings and cylinder head gasket.
Now I would expect that on a new car but........................
-
I read through (some) of the ceed thread you posted in, and watched the video.
Two things come to mind (and I think someone, perhaps it was you! said this was BS on the ceed thread) but the i30 glowplug system is designed to heat for a varying amount of time depending on the input fuel* temperature. I can pull the tech specs later, but my memory says that the length of glow is supposed to be from 1 second in "warm" conditions and will vary all the way up to SIXTEEN seconds when it's really cold (my memory says -15, I'll check later)
*Maybe the fuel temperature sensor is faulty.
There was also some speculation that the dash light might go off before the plugs have finished there work (it shouldn't). You could test the theory by waiting for the car to go cold ovrnight, and then before starting try turning the ignition to the glow setting anf back off a few times before starting, and check for smoke. Maybe you tried this already I didnt read the whole of the other thread.
-
I checked. According to the specs, the relay operating time should be:
+50c = 2 Seconds
+10c = 4 Seconds
-10c = 10 Seconds
-20c = 16 Seconds.
If this is right (source:P0670 in DTC@GSW) then starting my car this morning I'd have expected between 4 and 10 seconds glow though. I got 2 or 3 seconds of indicator light.
-
Implicit in what you are saying is that the plugs are no longer powered after the light goes out. I assumed that the delay was simply to ensure enough time for the plug to get to optimum temperature... and that power was still applied (and plugs were still hot) until the engine started, then once started, the plug temperature was maintained by the combustion.
If the power is dropped when the indicator light goes out the plugs will immediately begin to go cold. No?
If this was true then the engine should be cranked before or immediately the light goes out, without delay.
-
@ Lorian, thanks for the info, why are hyundai common rail diesels different from every other common rail diesel, my last car ford with common rail, never saw the glow plug light, only came on when -7 & then it would blink on for 1 second. Other diesels i have owned, once glow plug light goes out, start & away you go.
The dealer & derv expert has gone through the system & no fault found. At the end of the day, most drivers will see the glow plug light go out & then want to start the engine, they not going to wait or guess how long they need to wait after glow plug light goes out before starting.
This does sound like a rant, but its not.
Cheers
-
I agree, and in fact I find the information about the pre-heat system all a bit woolly. I've never seen the light on my stay on for more than 2 or 3 seconds to be honest.
This morning when I started my car (-1) there was no smoke. Some minor steam for a while as you'd expect, but it started and idled perfectly.
I can't help feeling someone in Hyundai must know the answer to your issue.
-
Hyundai Uk car coming to inspect the car, which is good, but not sure what they will find, if they confirm to much smoke, will go to court to reject, will also try another derv expert & hopefully they will experience problem at its worse, but it is masked by the condensation now the cold weather is here.
-
My guess is it would probably fail the MOT emissions test
-
@ Shambles, its a smoke issue only at cold startup, any other time all is Ok, so it probably would pass an mot test annoyingly, unless they started from cold & saw smoke and faild car that way, however it does not do it every day so potentially could book it in for 3 MOT's before they experience fault, fingers crossed hyundai techinical can sort.
-
Update on my problem (lots of smoke on cold startup, service found two glow plugs have blown out (not the fuses, but glow plugs)).
Now that temperatures here have reached -15C, my car barely starts... And looks like smoke grenade for a minute. I called the dealer to check if replacement glowplugs have arrived (115EUR each!!!), and he said that as cold weather set in, they got 4-5 i30 Blue Drives with the same problem... He said they are consulting with Hyundai on what to do, as glowplugs aren't covered by warranty. They will probably replace without charging, but it may take time. Also he said that one guy found glowplugs for this model for a lower price (30EUR or so) somewhere, so it might be in my interests to buy them instead of waiting for replacement by Hyundai (BTW, he also has bought same model, so it's his concern now too).
I wonder what can be causing glow plugs to blow out? If there's short somewhere, then the fuse should blow, not the plug. And what's also interesting, that looks like it happened over the summer, as it became apparent with the very first colder morning in the autumn...
-
I wonder what reasoning excludes glow plugs from warranty.
-
Im meeting with hyundai technical 16/12/2010 sod's law the car behaves, but can at least show the guy video footage of the problem.
-
Try and get video on different days to prove this is a consistent problem. It would serve to strengthen your case. I would also keep the video going a little longer showing the view of the exhaust pipe.
-
Again the same thing with my i30 this morning and the morning before, etc (it's been around -5°C for few days).
Not that much smoke actually, but when I turn on the car (cold mornings/days), there's some blue smoke. It's like it bursts out of the exhaust and after 1-2 sec there's no blue smoke anymore. Just normal amount of "white" till the car gets warm.. But really just a bit. Oh and yes, it does start a bit "harsh".
Of course I always wait for the light (glow plugs) to go out. Now I'll also try waiting few seconds more. I really don't get it why they are not covered under warranty.. Especially if that happens to a 1 year old car for example or something.

Hi Accim.. Nice to see you (have you been busy .. a bit quieter than usual lately :wink:)
Sorry for the off topic :mrgreen:

Hello!
A member on Slovenian Hyundai forum had similar problem, but her car didn't even want to start or started really hard and after long time.. I also gave her link to this page (topic) for help and it turned out, the problem was really like Lorian described on the previous page. The glow plugs burned out (all four of them), because of that metal or smth.
Anyways..they somehow found 4 new glow plugs on stock in Slovenia (which was not that easy) and they replaced them. They also fixed that thing, which "burned out" the plugs. Everything was done under warranty (she didn't pay for anything!) So that's good news. For now, her i30 seems to be okay.
Here's link to the forum and her explanation (which she got at the service). It was translated with google translator, so it probably "sounds" weird/funny.. :faint: :winker:

Here is another tip for folk who have the bluish smoke on startup, that would be worth a try. A chap on the Kia forums says his problem wnet away when he started using millers disel addative:
"The problem I had was definately incorrectly combusted diesel - you could tell by the smell. I tried a diesel treatment (from Miller Oils) and this cleared the problem within a week. "
On my i30 i've used miller's "diesel power ecomax" at least once a month since new.

In my I30 two glow plugs burned out. Prior to glow plugs change (single-handed, because blockheads from Hyundai Service affirmed that I refuel bad fuel :evil:) , my motor was smoking (blue) in the cold morning. Now there are original Mobis plugs but marked NGK (earlier there were tacky plugs marked Yura-tech). Now all is OK.

That is very interesting (The first time I have heard a brand of glow plug mentioned) sounds like there could be two issues with the glow plugs which could cause the smoke problem, shorting and glow plug quality... :goodjob:
I could be wrong but i think there have been less problems with glow plugs for our Aussie members Korean made cars (and these have been primarily a shorting out issue) whereas the european cars may be due to the use of inferior glow plugs.. :idea:
I could be on the wrong track but I don't think any of the earlier Korean built i30's owned by our european members have had glow plug issues??
-

Mine is over 3 yo and still the original glow plugs.
No problems to report

Probably you are right. Installed by Czech factory plugs brand Yura-tech burn out, in european cars, very often. Glow plugs aren't under warranty, but cost only about 70 EUR -per all four, and replacement is not difficult.
Start-up before glow plugs change

Start-up after glow plugs change
I' guessing that was before the change.
I dont have the details to hand, but there are at least two different part numbers used for glowplugs in european manufactured cars.
-
Is that photo after :eek: glow plug change :confused:
Surely you mean before...
Sorry!!!
Before of course!
For my I30 built in 2009 october, part numbers used for glowplugs is 36710 2A100.
-
There are 3 types of glowplug listed in the catalogue for European produced cars with the U2 engine if I understand the information correctly:
36710-2A100 used on 4 speed automatics produced up to 30/04/2010
36710-2A200 used on Euro4 6 speeds plus 4 speeds from 30/04/2010 onwards
36710-2A700 used on all Euro 5 6 speeds (with DPF) production
It is interesting that you have 36710-2A100. This would tend to indicate you have a 4 speed manual gearbox.
Its more interesting that the use of 36710-2A100 stopped in April 2010 - perhaps they found an issue with this part variant? Perhaps 36710-2A200 is a better version and is compatible? I don't know the answer, all conjecture on my part.

If they 2 burned out, you should really have it checked - the metal thing, that's probably causing the problem and which was described on the foreign forum (my link above). Or even better, you can read it on the 2nd or 3rd page of this topic..

Salesman told me that, the 36710 2A100 are identical like 36710 2A200.
-
Interesting.. never seen one out of a motor before :goodjob:
-
I think there MUST be a difference as they would not have two part numbers, they have seem to have really tight control on their bill of materials.
Of course the difference might be nothing to do with them blowing.
I think the make might be significant though, NGK sounds like a better bet.
-
whilst digging about in the part catalogue I've found the air intake heater that sooty mentioned. part number is 367102A300.

I had 2 of glow plugs blown out. At first service said that they are not covered by warranty (as written in service book) and cost 115EUR for one. I could not believe it and didn't leave this matter until they confirmed that there's translation error in service book and glow plugs are in fact covered by warranty. So I got them replaced under warranty. So you should check it out - I suspect that distributor in Poland is the same as in Lithuania and there might be the same error in your service book.

Perhaps it's true that there's translation error in service book (I don't know about it earlier) , however services play dumb and abuse this writing. You have found the honest service.

Interesting.... I just read a report from someone who had similar issues. They seemed to imply the dealer had said that the bosch-made glowplugs are a little longer than the other make, and the shorter ones were allowing carbon to build up causing them to be ineffective.
This owner reported no problems since having bosch glowplugs fitted.

I'm not sure that these glow plugs are ok for "Blue Drive" line of i30 CRDIs. Maybe glow plugs are different for Blue Drives and cost much more?
I didn't find honest service. They did everything to charge me. I just found the right people to notify about the problem...

Just had my car fixed under warranty re smoking on cold start up issue, which started to surface I guess about the 30K mark. car is 12months old and has now done about 64K. The technicians apparently found an "internal fault in the glow plugs". So they replaced all of them under warranty. The interesting thing here is that the report said the vehicle was tested and all OK. I'm sceptical about that remark because the engine was still hot when they tested it. Anyway I'll check this myself under real world conditions (ie in the morning).
I should point out that my first i30 was doing the same thing, so this isn't an isolated incident. That makes two consecutive i30 over two different model years me. I suspect this is more common than (proud) owners are prepared to admit.
-
I suspect this is more common than (proud) owners are prepared to admit.
Or notice. I suspect drivers in a more temperate climate are less likely to see the problems anyway.
-
That is quite possible Lorian. By the way I had the car in last week for replacement glow plugs (under warranty of coarse). They said the car was tested and all OK. Well that was just f**king crap. It's worse that it was before. Now I'm also getting the smell of exhaust fumes in the cabin, which is noticeable when the fan speed is on 1 and open air vent is open. Going back tomorrow to sort this issue out for good (hopefully)
-
Good luck this time. It would be interesting to see if there is a correlation between the issue and one particular make of plugs.
I wonder how sooty is getting on, he hasn't posted an update in some time.
-
I'll get back to you.
-
My i30 is sorted, however, even after the glow plugs where changed fault was still there but as the days went pass and the mileage increased, the fault became less apparent & has now gone.
car has done 5K miles, used 0.75 litre of oil, only manages 45 mpg driving sensible, the engine improving all the time, shame the suspension isnt as knock from front end & ratlle from dash which can wait, overall very disappointed with car, especially the dealer.
-
Had the car back at Hy service re this warranty issue. All sorted now. Took about an hour. Another techi realized that the previous junior techi who installed the new glow plugs had smeared too much sealing gunk on the actual plugs and around the area to be sealed. Consequence: the excessive gunk was causing the glow plugs not to earth correctly and hence not work properly. The plugs need to be earthed to work and the plugs apparently run for a few minutes when the engine us cold, which I wasn't aware of. And the fumes I was smelling in the car was the continual burnoff of the excessive sealing gunk. I started the car this morning and the car idled beautifully and there was no smoke.
This occurrence sounds like the problem you had sootytorques. But I think in your case you unknowingly allowed the sealing gunk to burn off sufficiently to allow the glow plugs to return to their earthed state.
My own experience with this issue has led me to believe that the earthing of the glowplugs are critical to thier correct operation. So anybody who still experiences problems after new glow plugs have been installed (and assuming the fuse is still in tact) may want to consider this in troubleshooting your problem.
-
Sealant?
Something like 20A of current should flow through each of those plugs, I'm suprised that any sealant all should be used. I though they were a kind of taper fit to stop leaks, but I dont know this for sure.
-
Yeah it came down to sealant. The first techi had apparently put sealant somewhere along the shaft. I don't know how much he put on and where he put it, but it was enough to stop the flow of earth.
-
I'm suprised also. In my car, wasn't any sealant on the glow plugs. These plugs are sealed in hole only by cone (metal to metal).
-
Maybe sealant is added as a precaution.

I hightly suspect it shouldn't be though. Perhaps one of our members from a dealership will see this and comment.

Question for the people that have had this issue: did you get any warning lights come on?
My 1.6CRDi is smoking somewhat on start-up and when I suggested it to the dealer they said they'd expect a warning light to come on if there was a fault with a glow plug. The vagueness of this ("expect"?) doesn't fill me with confidence!
They've also suggested I put some cleaner through. I believe this may be a contentious one here, but presumably there's no harm that can be done by putting a reputable brand through? I was going to pick up some Forte.
-
Question for the people that have had this issue: did you get any warning lights come on?
Good question.. I don't recall anyone mentioning a light coming on when they have had this problem :confused: If you don't get a direct answer in this thread after a day or two send a PM to very amicable members eyecon or Opa_1 (in case they don't notice this thread)
My understanding is that a failed glowplug creates QUITE A LOT of smoke (although our CRDi didn't have this problem... :cool:
-
di have a new i30 (1,000km/600miles) and it smokes every now and then no start up for a second or two....nothing to worry about? And it wil make smoke if you put your foot down hard! :P
-
Hey Guys,
I have had the smoke on start up also. Looked through the service details for the car and the previous owner had asked for it to be looked at in the past. After reading this thread, i had a look at my car. The 80amp fuse is blown so it is booked in tomorrow.
What are they called? while i was in i referred to them as glow plugs. I was informed that the car doesn't have glow plugs even though the fuse is labeled glow :exclaim: :question: :exclaim: :question: The service guy said that he has never seen this fuse blow.
So for the next day i have a 2000k old elantra to drive.
Report back with what they find. :whistler:
Boris

I spoke to the Hyundai dealership today and told them about it. They will look at it they said. They did however tell me it is quite normal but because I raised the issue they will look into it. I do not think it is abnormal though....particularly as my car is only 2 weeks old with 1000km on it! lol
-
What are they called?
As you said... glow plug (glo-plug). :rolleyes:
If they don't get fired up the starting may be erratic and combustion incomplete. The white smoke is unburnt diesel.
Blown fuse sounds like you found the reason... possible cause is a short to ground (engine block) in the glo-plug power circuit.
-
My car has done 100,000 km now and still no smoke on startup since changing the original glow plugs... Touch wood (tap tap on my noggin)
-
But why would mine be doing it only on cold cold start ups? its only got 1k on the clock.... I think its normal but will ask the dealer...
-
I think it's definitely abnormal. I'm in Sydney with colder climate than you and the CRDI does not smoke at all here. Ask them to have a good look at the glow plugs.
-
I'll ask them thursday but its only a little puff at start up....
-
Ok i got it back sorted,
they replaced the fuse and informed me that the glow plug rail was shorting on the heat shield. They informed me that this work was not covered by warranty but they wouldnr charge me this time. He said that someone had to have played with it back there and misaligned it :scared: . I then informed him that this had been reported by the previous owned on the 15k and 45k services (must have been winter) and no fault was found. All i got was OH ... i see ....
while it was in i got the lower front window trim replaced because of discoloration and, this will make you :rofl: (no you dirty minded people, it is not wanking) i had them replace my rear view mirror ... i had a rattle in the car that i couldnt find. On my trip up to Qld the other week, my passanger found it. bloody mirror was rattling on course roads.
lets see how we go over the next few days

I think Opa_1 had the same issue with the Glow Plug shorting out...Glad it was fixed (annoying how they made out it was a favour though...) :rolleyes:
-
I loved it when he said that someone had been playing back there ...
-
I'm really anxious to see if mine is an actual issue or if it is normal to have the little tiny puff of smoke on cold start up. SIGH! lol! I'll get them to check the fuses
-

That is right, I had the same problem with the glow plug shorting.
Took two trips in to find it but has never caused me any problems since. Originally it only really smoked on a 'cold' cold start similarly to what bryanj86 is experiencing. :)
-
OK ..
Normally in the morning when i start the car, even if i don't have the smoke and hunt, i could smell diesel as i reversed. Not this morning.
so far so good
B
-
Took it to Hyundai yesterday. There are no issues. Small amount of smoke on start up is normal according to them. I also asked a few others who have diesel cars and they all said that it happens to them too; a little puff but nothing major. So i am satisfied that my car is fine now....but ANY increase in smoke and I will be giving it back to Hyundai to look at lol
-
Bryan,
If it is a little puff i would say you are fine ...
I am talking about the car hunting 800 - 900 rpm and th esmoke put out is dense and would fill the volume of a 6" male. Thats not a little
B
-
I think there is a video here in one of the smoky diesels threads of what glow plug problems look like in terms of smoke output, and it isn't a small amount of smoke. It's more like a choking amount of smoke.

I have 2009 MY diesal manual and is has been blowing blue smoke on start up, started after a few months, it is now abnormal in the first start of the day, it is not using oil, now at 59.000ks. Will be taking it back for 60,000ks and getting it looked at. Another issue I have had is the cruise control stops working on long trips if I stop after 500ks and no amount of pushing buttons makes it works again, third issue is the ESC system warning light as swithed on for no reason then turns off. This has happened twice.
Other wise I very happy with the car, best fuel range has been 1,156ks on a trip to Phillip Island from Sydney.

i'm on my second i30 CRDi & still have not had a glo plug problem, touch wood. i have never once tried to start my cars till glo plug light goes off. the first car i got the light took longer to go off, but the i30 CRDi i have now the glo plug light goes off very quick. 15 years back if you kept starting a diesel before the glo plug light went off you eventually burnt out the glo plugs. but the new truck the light goes out very quick like the new i30 CRDi. strange you can still start the cars with glo plug not working, as i had to use eather to start a truck once when glo plugs failed. the motor would just turn over but not fire up. was mechanical injection no turbo.
i'm thinking the the combination of turbo & catalist in pipe cause the smoke from unburnt diesel fuel in pipe
-
I was under the impression that the turbo did nothing at idle revs, so starting should not engage the turbo at all. :neutral:
-

I would say that is true but once motor starts runing the force of the exhast gas's will spin the turbine. as the turbo uses ball bearings does not take as much force to turn the turbine thats spining on ball bearings. but i'm still wondering how the motor starts at all cold with glo plugs not working at all? have you ever started a Diesel that never used Glow pugs? it was a lot more work 50 years back.
-
Well my car smokes only for the first few seconds on start up and I believe it is NOT glow plug problems. It just does it. I asked the Hyundai people and they said it was perfectly normal and nothing to worry about....IF it was only at the first puff at start up. :)

That sounds fine (it is about the degree and duration of the smoke) Light smoke for a very short duration is unlikely to be Glow plug issues (as you say) :goodjob:

Lakes
In Australia, I would say apart from up in the high country, glow plugs are not necessary. The high compression ratio provides enough friction heat to create ignition temps. That said, I always wait for the light to go out before starting. With the glow plug glowing and starting at the same time, it seems to me that the maximum element temperature on the plug could easliy be exceeded, thus shortening the plug's life IMO. :neutral:
Regarding the turbo, yes it spins at idle probably but everyone says the turbo becomes effective at 1700 revs + so although it is spinning, the boost provided would be negligable. Perhaps someopne with one of those boost monitors could provide some info. :neutral:

One thing you could do is film it, put it on youtube or something, and then the rest of us can gauge how it is and tell you if any of us other CRDi owners experience anything similar.
-
I believe the smoke on start up is perfectly normal and in fact, indicates a well lubricated engine. If you've ever seen a piston aircraft engine of the 40's on start up, it's pretty full on. You could be forgiven for thinking that the engine is clapped, but what is actually happening is the residual oil from the valve stems and some upper cylinder oil simply burning off. This oil collects after shutdown and I am quite happy for it to be there. Diesel fuel is an oil after all. Naturally, if it continued after start up or was excessive, then I'd be concerned.

My car does not smoke on every first start if used frequenly, however if left over long weekend or longer on the first start it can blow blue smoke for more that a few seconds, I have seen great clounds of smoke on one occasion after left it for few days. If dealer looks as the car it will not smoke as they are unlikely to leave the car unstarted for more than one day. I checked the Glow Plug fuse but cant get it out to check if okay, have never seen glow plug warning light.
Possible causes are oil leaking past the inlet valve stems, injectors leaking when the engine is left for a time, blow fuse for glow plugs. The engine does not use oil, so I suspect it not related to pistons and rings.
How do check the 80 amp fuse?
How does it come out?
-
On our car its the little bottom left light on the RH instrument cluster. It is mentioned in the handbook not to start the engine until it goes out and then to start within 10 seconds of the light going out. :neutral:

When the glowes are damaged this indicator does not light. The light goes out normally after a few seconds, despite a damaged one or more glowes. In my car it was, I had burned two glowes. In the morning it looked so (see picture on page4).
The fuse you can check by multimeter (after removal of course) or by battery and bulb.

I don't feel this is normal as I have never seen it with my CRDi. If you have a phone or camera film a video to show the dealer what it's like at its worse.
-
I will have to agree with 847563 on this one. Mine only smokes on start up after leaving it overnight or long periods; not just a few hours after coming back from shopping etc. lol.
ALSO...i am curious as to why our diesel engines done smell the same as the truck ones on the highway??? The truck ones have the typical diesel smell about them when behind them but mine seems ot have a sweeter note to it haha!
-
bryanj86
We all use the same fuel at the servo, so my guess is that because our engines are so much smaller in capacity, the ratio of exhaust gas to air coming from our cars, is quite low and this may trick the nose into detecting a "sweeter" smell. :neutral:

:goodjob: Problem solved! Most cases of strong blue smoke at startup reported on the Polish forum is caused by defective glowes. My engine also firmly shook for several seconds. Apparently was I30 series with poor glowes.
-
I still think it is normal though to have some smoke on start up... you look at all the other diesels on the road when they start up and they have some smoke come out.... But that is so great they replaced the glow plugs..... :)

No modern common rail diesel should smoke at startup.

Mine doesn't.
Actually, I was following this thread with interest and was surprised at the final result. It was my belief that blue smoke was from burnt lubricating oil - the sort you see from cars with worn motors taking off from the lights after idling.
Whitish smoke I thought was from unburnt diesel fuel and not smoke at all really. This is what I would have expected to be fixed with glow plugs not blue smoke. :confused:
-
I have stated before that smoke on start up is not necessarily a bad thing. I do agree however that today's modern engines when new shouldn't smoke. This is because the oil control ring(s) are doing their job and no oil at all leaks past the valve guides when new. I would expect some evidence of smoke after 30-40K's (18-25K miles). Even then it should only be a puff at most.
Some car makers make exceptionally good motors with good oil control, others, well. :exclaim:
It would be handy for those commenting to state their vehicle engine distance so adequate comparisons can be made. Our cars, 21K, no smoke, 55k a minor puff after overnight rest.
-
Mine is a 2011 model with just shy of 15K on the clock. It has a small puff of whiteish smoke on overnight start up....
-
I had a similar issue with my 11 plate i30.
It would randomly puff out a lot of smoke. By "a lot" I mean that you could see the smoke in the wing mirror and then it would look like a cloud coming towards the front of the car. I always allow the glow plug light to go off before starting. It was even happening when it was 30 degrees outside, the car was hot and only left for 2 hours.
Dealer couldn't find the cause of the problem.
The problem is that it does not always happen.

Doesn't sound quite right (but it is odd that it is intermittent.) A few that have had glowplug issues causing smoking (including Opa_1) have found the glowplugs were earthing on the block, but fairly sure the smoke on startup was regular until glowplugs replaced :cool:
-
@ skalra63 its your glow plugs that need replacing, get the dealer to re check them, when I had theis problem it took nearly 2 months to sort, it would have been quicker if the dealer knew how to check glow plugs, also take a video of the problem & show dealer.

I have already spoken to them 3 or 4 times. They have only been able to reproduce the problem once but couldn't find the cause.
They said they checked the glow plugs and injector but couldn't see anything wrong.

I had mine serviced last weekend and they used a new oil in it. One that glows under UV light to detect leaks (if leaks were ever to occur). Since i had it serviced i have not seen smoke at all. It still smells a little on start up as most cars tend too but nothing untoward!
-
And the oil was ?

Castrol fully synthetic someting arother lol

They probably used injection cleaner or added it to your tank, does it list this on service ? don't know about the oil your useing, i'm useing Mobile 1 0w 40w, but i think the ELF oil i used in my first i30 CRDi was a better oil
-
Yeah they put in the cleaner into the tank :) They used 5W/40 oil for mine...

white, blue or black smoke - possible causes in high pressure diesel injection systems
diesel contaminated with petrol
diesel contaminated with water
sticky injector jammed open
no engine coolant temperature sensor signal
no rail pressure sensor signal
erg valve blocked open
fuel pressure regulator valve stuck
oil level too high or low
clogged air filter
faulty glow plug system
low compression
