I don't really know the answer to your question however I am currently in need of a fix to my A/C as well and there are a lot of posts on this forum about messed up compressors so it's possible that this is a huge problem with 06 V-Dubs and there's a shortage of parts.
FYI, I had an appointment to get mine fixed today but cancelled for two reasons. #1, Joe Heidt motors has the worst service department I've ever encountered and I'm still scratching my head as to why I bought my second VW from them. They won't give me a loaner car even though it had been negotiated upon sale. #2 I was able to have my new exhaust installed today and between more power and A/C I'll take more power every time.
I just got off the phone with Palisades VW/Audi and they gave me an appointment for tomorrow and are willing to give me a loaner for $12.00. Although I'm not thrilled with the $12.00 charge, at least they were accomidating, Joe Heidt has scrappy hours and they offer nothing in the way of real "service."
Anyway... I'll let you know how quickly they fix it and get it back to me. Oh, and once again -- Joe Heidt BLOWS... and did I mention they really blow!!! Now you know why I really posted.
