The glovebox brake tends to stick on the A4. Mine did, and it was a devil to open and close. Audi actually has a TSB about it because it has become a known problem. I fortunately found the TSB before the warranty ran out, so it didn't cost anything to fix. At least I was lucky and didn't break the door like some people have.
