With my A3 (10/03) I have found the following defects and/or points and will soon meet my dealer: – known front disc fault – known error in the belt guide – motor rucks in idle mode – fogged fog lights (after 8000 km!) – slight distortions in the rear window – hopping on the highway: Although annoying but not dangerous at best will (attraction). I would like to talk to him further about the following things: – re-calibration of the xenonsch Einwerfer – Reprogramming of the locking system (autom. closure) – Impact on the life and quality of the xenon headlights by the light sensor (coming/leaving home) Who has made what experiences to the points? What is the status of A3 colleagues?
