I'm fairly new to A4 ownership and the car has been superb so far, but in the last week out of the blue I got in the car one evening and the interior light wouldn't turn off after I had shut the door.
Naturally I checked that all the doors were closed properly and they were. Then shortly afterwards all of the red lights on the switchgear of the drivers door went out and they haven't come on since.
The central locking doesn't work properly (I have to use the key each time to lock the drivers door) and all of my electric windows don't work now either, which suggests to me that something is shorting out.
Finally when the car is locked the flashing red LED on the drivers door just stays on constantly rather than flashing.
Something is clearly kn4ckered.
I've checked the fuses and all are fine.
I've also taken the drivers' door card off to check all of the wiring and can't see that anything is out of place.
Can anyone give me any pointers as to what it could be or what possible solutions I could try? Is this a common fault? Am I looking at a huge bill?
Any help would be much appreciated
