They believed the fault.....however they said there was nothing they could do because the fault wasn't still present in the car. Unwilling to even investigate the RAC report codes i gave them, just said there was nothing they could do.

AC have been a total nightmare from day 1

What's even more frustrating, is that the plonkers would still have no idea how to fix it if the sensor jumped out of the car and smacked them on the nose.

Complained to Kia UK yesterday, their response was to call the dealership who stated they couldn't diagnose the problem as the fault code wasn't present in car.

Code brings up a multitude of things (maybe 7 possibilities). Service manager says he cant hookup to diagnostics and work backwards from the code (whatever that means) to troubleshoot and find where the fault was coming from.

fundamental flaw in the system if RAC can "fix" your car to a state where the cause of the problem cannot be investigated by the dealer.

In todays world of computers you would think the codes would be retained somewhere in the cars Central Computer System!

should probably send this to Kia right?

How would the RAC tech get your car out of limp if he did not reset the ECU? It is unclear in your posting whether AC even tried to read the ECU or did they just accept you saying the code was cleared. Some cars retain information in their computer even though codes are clear and which only the dealer equipment can read

I'm only surmising here, but i assume AC are not Kia dealers, as such presumably they will not have the full dealer diagnostics which may well find the original fault logged in the ECU memory, not visible to a generic diagnostics reader.

Whether this is the fault of the RAC chap or not, i have to say that Kia haven't proved particularly helpful, it wouldn't have hurt them to arrange for your nearest dealer to run your car through dealer diagnostics, maybe not helpful as AC the seller and not a main dealer, but that is only a guess.

My line of complaint will now focus on a like for like replacement at the expense of RAC.

Is that getting the RAC to replace your whole car? All they have done is get you moving and they haven't damaged anything - so you are unlikely to win anything here. Presumably you have read all the RAC small print!

As for RAC "Are they working in cahoots so dealer doesnt need to investigate?" - the answer is NO.

As far as the dealer is concerned I can see their point. If all the detailed issues have been deleted from the car how can they investigate the fault? The printout would have been more generic and will not give enough detail to diagnose.

I myself had wobble with my Superb just after I bought it (was 14 months old) and it popped up a management light in Germany - turned out to be my fault after filling up with petrol - was told "One Click - Halte!!!!" at a great German Skoda dealer. It's been faultless since but I'm careful filling up now.

I had a car from the same stable that refused to accelerate, even down hill (auto) and even slowed if the accelerator was depressed further.

No fault codes were generated so the dealer couldn't do anything and of course they never materialised on the dealers test drives.

I had to film the dash - 3500 RPM, 50MPH, flat out down hill before the dealer did anything and had to call the manufacturers technical support team for advise. The throttle assembly had to be changed and touchwood the fault hasn't reoccurred.
