I have a 1.8T Sport A4 and when it is supposed to be idleing the revs jump around a bit? Any ideas people i have a warrenty for it, and id like to go to the garage with some knowledge so that they can not try and con me. It has climate control but that is turned off at the time, and so is everything else radio etc. This is my first Audi so i am not sure where to look. It is hopefully going to AMD in a week or so for a remap update etc would that help sort it out? Thanks for you help people.
