To remove the battery, there is one hex bolt holding the battery in place. This is located in the front/middle of the battery (it's difficult to get at). You're going to need a really long hex wrench to get this undone.

I had a Yellowtop in my 06 A4, as far as I know, there's only 1 size. It fit with no problems.

Anybody have any photos of how to get the old battery out and the new one in?
