I know that early A3 8Ps had a weak wiper motor and many have been changed under warranty, but has anyone who has had their motor replaced had it fail a second time? Mine was swapped out by Audi Assist a few months ago, but the "service park" mode hasn't worked since. My local Audi dealers have a further new motor on order to see if that restores the "service mode" capability, but I'm still waiting for stock to arrive and now my replacement motor has stopped working altogether again... I can accept a failure and one replacement, but to have the second motor fail soon after seems very worrying. Has anyone else suffered this double failure?
