I have An A3 140 2007, which has had a decat, full exhaust system, and a remap. The company who remapped it is reputable, and has lots of positive comments on here. Since the remap, it smokes between 1500 and 2000 rpm when in traffic at part throttle. Just a puff of smoke, but alot in that short puff. I've had no other issues, and its been a few months since I had it done, but yesterday it lost all power, and wouldn't do over 40 mph. The engine management light didn't come on, and after I turned the engine off and re-started it seems much better, but now feels like it only has the exhaust work done, and no remap!!! Does anyone have any thoughts of wisdom that might help me out?
