Just picked up a B6-A4. The car was side-swiped on the passenger side, and the repair looks good however the attention to detail is appalling. My friend (who sold it to me) wasn't aggressive enough with the repair shop to make sure everything was working, so now it's up to me. I think I enjoy the challenge.
So the remote key (both of them) functions don't work.
I know that she had a new battery put in the car, so I went through every reset procedure I could find (on this webiste, and in the Owner's Manual) with no success.
Next step was to install a new battery in the remote. This also did not make it work. I thought maybe the antenna was the problem, so I tried the remote near the right rear wheel well - no luck.
Is there any way to trouble shoot this system? I think that I'm going to start in the right rear wheel well, seeing if I can get access to the unit (what ever it is called - receiver?).
Maybe I need to look at fuses?
Any other advice?

Thanks!
