Fitted a relatively new Throttle Body today. (Only done a few thousand miles according to seller and did look in superb condition) Still have this: 17967 - Throttle Body (J338): Fault in basic settings It won't clear the codes and when I try and do the TB Adaption, my VCDS doesn't show up in the corner ADP RUN like Ross Tech website says it should do?? Been for a drive, got 5 miles down the road, wouldn't rev past 1800rpm without the revs dropping to idle and then back upto 18oorpm and so. Turned car off and on, then it been fine again for 8miles. Still slight hesitation on accleration but no more revs dropping as soon as i touch the throttle pedal. Also, fitted a new driver side wing mirror glass as it had split and the heater didn't work. Passenger side is fine. Fitted new glass, and now the drivers mirror is ALWAYS hot with engine running and passenger side isn't??? What controls the heated wing mirrors? The passenger does work in the morning when there is a bit of dew on the glass, it soon clears.
