After rain, car thinks door is open and alarm keeps going off
Hi all, I hope you can help me with a problem with my A2.
Its a few years old and looks immaculate, with only one severely annoying problem! When it rains heavily, for the next 12 hours I constantly get a "door open" warning light on the dash. The alarm will go off within 15 minutes of locking the door too.
I have checked that all the doors and boot/trunk is closed, yet the indicator still shows something as open.
I therefore think that water is getting onto something (door sensor)and is causing the car to think its open. Is there anything that I can do to fix this? are the sensors easily accessible? could it be electrical problems not in the doors, but maybe in the engine?
Any help greatly appreciated,
Thanks,
Craig
