The owners manual explains how to reset the wrench button. It is quite easy. I have an 06 quattro with a 6 speed. Love the car. The 06 has no recalls other than the coils.

 

There have been some posts on this thread saying that there is no need to worry about the high pressure fuel pump cam follower. That may be true (to some extent) on 08 and newer engines, but on 2006 and 2007 models, please look up Audi TSB 150702tsb (2) that clearly states what the problem is, what codes will show up and how to repair the failure.

Better yet, rather than wait for the failure, simply change the follower every 35 or 40 thousand miles and save yourself a few thousand dollars.
