My central locking has failed on my A4 Avant - there is power to the bi pressure pump but every time I press my remote control it sounds like the pump is running for 10 to 15 seconds but it is not operating the door locks - is there an absolute way to check if it is the pump or could it be something else? thanks
I recently changed the pump and it works fine. Thanks to the guys from Audiworld for all the tech articles. Here's a link on how to replace the pump. Good Luck!
