Whenever i try to lock the doors, i hear a buzzingsoundcoming from the door behind the drivers door. It stays buzzing for a couple of seconds and then it goes away. i dont know if the selenoid is bad or what?


2001 Audi A4 2.8

 

The locks are operated by vaccum, but if something is buzzing after locking the door then its the door latch. Everything connects to that latch.

 

So i just need to change out the latch?
