anybody know where i can get replacement windshield wipers and how they are installed? i understand there are something like 5 different ways to secure wiper arms.

 

Gotta get your replacement wipers from the dealer. They usually un-clip quite easily... it will be easier to understand how they clip in when you pick up the replacement wipers. If you have any questions just ask your local Audi service writer he'll probably just show you how to do it if need be.
