I just baught a CPO 2011 A4 premium plus and I am trying to program the homelink. I have cleared out the previous codes per the owners manual and followed the procedure of holding the garage door opener at the front grill until the lights blink. It still will not operate the door. Any suggestions?

 

There is another step sometimes, after you hold your opener to the front and the lights flash twice, push the button on the garage door opener (learn button), then get in the car and push the one you want to program - I think that is the correct way, haven't done mine in awhile.
