Wondered (kinda praying really!) if someone could help shed some light on this ? The car is a 2006 2.0l tdi 170 BMN About 2 months ago & after having no end of issues with the DPF the car was taken to AMD in essex to have a DPF delete & stage 1 re map performed. On the drive home the car obviously felt very different, but a couple of issue that were noticed was i couldnt get a smooth gear change like i had before & an increase in revs whilst changing gear when the car was driven slightly harder (like over taking).....when driving around town everything was fine & the revs dropped as soon as the pedal was pressed...& it only happened when changing gear at around 3k... & the higher the revs when changing gear the more the slight increase in revs when the clutch pedal was pressed.....there was never any issue with the clutch & it always engaged as it should about half way through the pedal travel. When I collected the car they said that it would have to get used to new settings so it was ignored for about a week, but the problem never went away!...Thinking the problem could be me...or perhaps a problem with the clutch... I asked a couple of knowledgeable friends to have a drive just to make sure it wasnt me being a muppet & doing something silly like leaving my foot on the accelerator pedal or something like that (1 works at Audi & the other works for Pro-drive) They both said the same thing..."something isn't right with the re-map...take it back" I phoned AMD who said it was more than likely the car still getting used to its new settings or the clutch switch (as we all know the clucth switch is a common problem on most audi's), So i checked the switch using VCDS but couldn't find any fault with it....worried that this over rev could cause early failure of the clutch & wanting the problem cured, I phoned AMD & they said to bring it back & it was booked in for a saturday, but due to the other half having stomach pains & a visit to the hospital on the friday night before (shes expecting a little one in a few months) Unfortunately i couldn't make the appointment so the car was re-booked in about 2 weeks later..(now approx 1 month after the map).... because i don't live very close to AMD I decided to book the day off work & took the car back to AMD to get the issue looked at. About 3/4 hour after the car was taken in by a tech they came upstairs & told me it was the clutch switch (brilliant i thought...problem solved)...so obviously i said change it... & a new switch was ordered from TPS....2 1/2hrs later (they arent quick these TPS guys!..lol) A new switch arrived........1/2 hour later the guy from AMD comes upstairs again & says.."its not the clutch switch as it still does it with the new one fitted!"..:-( BUGGER! So they decided to remove the map & put the ECU back to its original settings & a tech drove the car up the road, on his return the tech said that it was still there but not as noticeable??...something which slightly confused me as ive owned the car for nearly a year before the map & have never noticed any such problems with over rev when changing gear...im not a new driver either having owned & driven a multitude of different vehicles over the 20+ years ive had my licence! so Im kinda hoping i have enough experience to notice something like this....also bearing in mind i wouldnt have purchased the car in the first place if it had this problem & i certainly wouldnt have booked it in to have a re-map with the fault already there !....because that would just be stupid! To cut a long story short...after putting the stage 1 map back on & sending me on my merry way....they dont know what it is!?... & when they were looking around the engine the only fault they could find was a slight oil leak from the actuator on the inlet manifold, but they did say that this wouldnt cause this problem...they also said it could possibly be a generic fault with this type of engine !! (wtf?)...which also confused me because if this were true then im sure there would be a stack of posts on this forum like this from other people that have had a re-map done & experienced this problem after. Im at a point now where i wish I'd just either left the car as is or perhaps bit the bullet & bought a new DPF filter & never had it mapped! AMD are saying theres nothing wrong with the map theve put on the car & everyone i speak to about it thinks its a problem with the map...... & now after 2 months the problem is still there! To add insult to injury on the drive home tonight it feels like the car hasnt been mapped at all...when i accelerate the car doesnt take off like it did after the map, but the revs do!...Im guessing this is the start of clutch slip & if this over rev has possibly caused this then im not a very happy puppy considering the car had a healthy clutch before the re-map ! If any of the knowledgeable people on this forum could shed some light on this problem it would be very much appreciated.
