I have a 2008 Audi A4 Quattro Cabriolet. My top is doing nothing more than lowering the windows to open. I have manually lowered the top and locked it down, put it back up locking it down on 2 separate occasions to see if it needed to be reset, but after both times only the same takes place. The windows go down when hitting the button. The top does not release or the rear deck not open. Is there a sensor that is bad I need to replace. Thinking abut taking it to the dealership to evaluate, but feel they will bend me over. Any suggestions appreciated. ThanQ!!
