Car: A3 2007 Sportback. Hello All, Got a problem that has been bugging me for the past week. The driver door won't open with the central locking fob, all others do. So I have to manually open it with the key. It locks fine with the fob, just that it won't open with the fob. I left the door open and pressed the fob, just to see if there was noise. There was a noise like a faint buzzer, same tone. Any insight is most welcome.
