My 52 plate A3 shows the Door Open sign on the dash most of the time.
It seems to be the drivers door as the sign will go out occasionally, particularly when closing it when the weather's really cold
When I lock the car, the doors will lock but the flashing diodes won't come on (guess this means that the alarm isn't setting as the sensors think a door is open?) - The courtesy lights in drivers door stay on and you can see them from the passenger side window
How do I solve this?
