Finally a faulty unit found,

Thanks to you both, but,

maybe it should read "Finally yet another faulty unit found"  :eek:

Yes perhaps.. Very disappointing  :disapp:

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.

Haven't used the product yet, I have a filled bottle waiting for the next refuelling. The filler tube is quite long and I don't want to add it without fresh fuel as well. :)

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

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.

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.

Are these not one & the same thing?
They have also replaced the brake light stop switch twice, apart from several other unrelated issues. (from the OP's original)

Or is the TPS at the Throttle body end under the bonnet?

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......

Sounds just like the symptoms that I had with the fuel bug.  Tried a fuel treatment yet?

No, I will wait until after Tuesday 9th April, when, (imo), they have carried out their final chance to resolve the situation.

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.

If unable they will have to agree to me trying to eradicate a possible fuel bug, without invalidating the warranty.

That's if I choose to tell them, after all their failed attempts :undecided:

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:-

Iím 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.

That's too bad, although with the high percentage of Diesels in Europe there must be a similar product available, surely.
