This is a bad one.... I have had this fault before and it seemed to fix itself. I was driving the car (2.0 FSI) on the motorway when all power went from the engine and the car begun to slow down. The power then returned a couple of seconds later. but it repeated this fault about 5 more times then it disapeared for good. It has now returned but is much worse. Its like the car has suddenly dropped to only having about 25hp and cant accelerate past 3000rpm. The fault thought is intermitent. I have taken the car to audi before and they said they couldnt find a fault. I can now not drive the car in fear it will do it again. The fault is returning much more regulary. The car has been chipped but this fault had occured before the remap. If the car is taken to Audi and they cant find a fault what should i do? Has anyone else had this problem, does anyone know what it could be? No warning lights are coming up on the car.
