Hi,
When returning to our A6 2.7 quattro 2006
The windows were slightly down. All windows went back up apart from the front passengers window which would only go down. We travelled home with the window down. When home we checked for blown fuses and removed and replaced some but none were blown. While locking and opening the doors with key in door the passenger window went back up in stages. We then found the doors would not open or lock with the remote on the key. The drivers door did open with the key but the alarm would not disarm and the car would not start and the alarm would sound. Then while trying to lock and unlock uif doors with the key in the drivers door car seemed to dead lock that resulted in not being able to open the car. Called the AA home start and somehow they were able to open the drivers door with the key in door although they didn't know how they did it but but the alarm would not disarm and would sound as soon as the door was pulled open and won't start. Help
