Hi people, I have an Audi A3 3.2Q DSG Sline, and have been through 3 sets of wiper motors in the past month or so. They work perfectly then just decide to stop. Even the Audi main dealer couldn't tell me what was wrong (but charged me £198.00 to tell me they were not working and refusing to fix under warranty even though my car is under 3yo). Does anyone have any ideas (my car has no bonnet switch, but is always reading as closed so it ain't that) Audi thought it could have been a weak earth? What do you think?
