Hi peeps Ok, I have this annoing issue with my 2001 AMK S3. If I start the car (cold or warm engine doesn't matter) the power delivery feels normal (let's call it 100%). Then I arrive at the destination and turn the engine off. If I then start up the engine again it has clearly lost some power. Car feels normal, its not juddering, it doesn't misfire or anything, it has turbo boost...It's totally normal except it feels like it has less power (around 20% left, this is of course different to measure but roughly). It simply feels a little dull!? It can also be the other way around. Car is started and it feels slower (a little slow, at around 80% of it's best) and then the next time i fire it up it just fly. Like its on stereoids. Now I know this sounds like it's just me and that maybe the weather plays a part but I have now had two friends drive it and they first didn't believe me. The first one I just said; hey try my S3 and see what you think (I told him nothing about the issue with the power)! We then drove for half an hour and he thought it was pretty normal (powerwise), meaning; yeah this is an S3 with 210hp and it drives good and normal. I then told him about the power issue, He kinda laughed but I told him to take the key out of the ignition, wait one minute and then start the engine. We drove back and the first time he floored it he went...; Oh my Fecking God...It's different. More grunt, more eager, more power. Like it's been remapped or something...We were both baffled by the reality... We took out a reading with VAGcom but it showed nothing, no fault codes, no sign of engine beeing remapped. Next friend to try it. This time I told him about it and this time it was the opposite way around as I drove to a place to meet him, turned off the engine while we smoked a fag...car feelt really good he thought, it drove really well for having only 210hp...I asked him to pull over and turn off the engine, and then start it up...we drove some more and as soon as it were safe to floor it he just couldn't believe it. It was definately slower than before?!? Cutting it really short; what is going on? Can you help me with this problem. Have anyone experienced the same or even remotely the same?
