I have an audi tt roadster 2003. I went to open the driver door and the remote wasnt working. tried opening the door manually with the key and it still wouldnt open. Opened the car by manually opening the passenger door which set off the alarm. Cannot open driver door from inside either.
At first could also not lock car with central button ( to lock yourself in ) in the car but after 24 hours it let me lock but still would not open driver door when took the central lock off. Tried spare key and that would not let me lock the car or open it. Car drives fine still and no warning lights have come up.
Any ideas anybody has would be appreciated.

 

I have the same issue, how did you fix it please?
