When i was switching my one of my door cards i noticed a connection which had come out of its female counterpart in the door. The cables joined near the door handle, but as my central locking was working im not sure what it was. As far as i know, nothing wasn't working, and now they're reconnected, nothing has started to work :S
Im guessing VW don't just stick random bits of wiring in, so what could it have been? (wish id taken a picture now)
