How to Maintenance manual-2010 A4
 

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.
