I need some help:
(1) Anybody know of a “how to maintenance manual” for the 2010 A4?
(2) Where is the micro filter located for the interior air and how do I change it? I think that the musty a/c smell is coming from there or the drain may be plugged.
(3) How do I back off the brake calipers so that I can remove and paint?
Thanks in advance to any replies. uwon

 

Bentley is the exclusive factory-authorized publisher for repair manuals for Audi. There are paper and electronic versions, with benefits and drawbacks to each. It has a fair bit of content, but there is much left out; and, it is sometimes frustrating to navigate. That said, they're still the best we've got (outside of Dealer-specific stuff, which you're not supposed to have, but is obtainable ).

 

Cabin filter is starboard, behind firewall under hood. Remove plastic top cover and you are staring at it. It pops right out.
