A lack of power may be noted and the Check Engine Light illuminated with various throttle system fault codes stored. Our technicians tell us this is generally caused by electrical connection issues at the throttle body. If this is the case a harness repair kit is available from Audi.Google+

Engine light keeps coming on. I had a mechanic look at it and he pretty much just turned the light off as far as I can tell. It's running a little run especially when first starting the car.
