I have a 2000 a6 2.8 quattro, and whenever I go to open my sunroof for the first time after turning the car on it doesn't open. But for some reason all I have to do to get it open is turn the dial to the completley open position and then back to the closed position. After that the sunroof opens and closes fine. And also I just bought the alluminum rings that go around the gauges, and was wondering what type of adhesive to use for those.

Any suggestions are appreciated.

 

Sounds like you are experiencing a bad connection inside the switch. I would replace the switch.
