I am 100 miles from a audi dealer so I've been trying to fix this on my own. I have replaced window modulars and that didn't help. The top will not go up or down. There must be some electrical hub that I need to replace but don't know what it is or if they are two separate things. Any ideas? Thanks

I own 2013 Audi A8 that has only 100000 km. It is 4.0 dual Turbo. The car is an amazing car and 2 months ago just stalled. Whenever i face problem I called Audi USA and they said it is A8 with only 100000 km so we need to know what is going on, I took it to PFAFF Audi in Vaughan and they said you need new engine.

 

I'm having same problem with a 2007 a4, just got car , if you ever found out anything let me know
