Just changed the battery on our 2006 A4 Cabriolet. Now the windows won't work, trunk won't lock, convertible top will not open, key fobs don't work. I have no experientce with Audis. I have found multiple postings regarding these issues in the forums but can't seem to find anything that solves my dilemma. Is there some sort of reset routine but I have to run after changing a battery ? Any help or some direction on where I should look would really be appreciated.
