I want your faulty electronics
Anti-corrosion, that's it.
I asked in my local Audi and the guy did not know the answer till he read my service book. Which I should have read really.
Took him out to the car and showed him the marks and asked about the issue with the roof strips lifting up and two rubber strips either side of the windscreen coming off and he said I need to speak to the manager who's back on wednesday.
I'll pop back end of the week and try again.
I might clean the car this time, so it looks better. That might help or its just my Bristolian accent that's causing issues. lol
