Hi, I have just bought a 2000 a3 1.8 turbo. I am having a problem when driving over 50. When I change gear and accelerate there is a severe delay (the car physicly slows down/judders) for about 2 seconds, and then it's fine until I accelerate hard or change gear again.
The car is completely standard, has done 66000 miles and has just had a service and cam belt.
I would be greatful for any help/info you have,
