Audi Repair: 1997 Audi A6 Sunroof Dial, audi a6, nice weather

Question
I recently purchased a used 1997 Audi A6 and the car didn't come with the sunroof dial.  Do you know of anywhere I can pick up this part?  Thanks.

Answer
Well if your local import junkyard doesn't have the part, it's a trip to the dealer I'm afraid.  Im curious if the simple replacement of the dial is all that is needed; normally the whole switch assembly goes bad.  When you try it, make sure it's nice weather and that you have a backup plan in case your roof stays open...  Good luck,  Jan
