I need to see if anyone else has had this issue;
My 2004 A4 3.0 Cabrio Quattro is having power seat issues, the seat will move on its own without touching the control switch to move the seat. I replaced the switches and that did not resolve the issue. It also seem to be the reason that my battery drains out in a few day unless I disconnect the battery.

Any suggestions? Kevin 443-677-456

 

I am having a similar issue I just got a 2004 A4 quatro, did you ever find the cause of the problem or the solution.
