I got a 2001 stock S3 - owned it from new and in 120k not a single engine component failed (xcept coil packs - all changed 20k ago) on it until a few weeks ago when it had to go in for a head gasket change -Rude awakening there!
Anyway, since then the car aint right -Under hard acceleration, it hesitates around 5k rpm in 4th/ 5th and the amber engine light flashes for a bit until I back off. I'm getting these codes from VAG com...
