2001 A8L: Door locks not working, Central Locking Unit...or hose...?
I've done a "search" on this topic but information is very limited. Here is my dilema:
The door locks stopped working, neither the key fob or driver's door controls make them work. Pushing the lock buttons down manually takes quit a push, maybe 3 or 4 pounds of force. The alarm still sets when the things are "locked" with the key fob. But the doors don't actually lock. I tried to find the central locking unit in the driver's side rear fender area by removing the cd changer and nav. unit - but I'm not sure what his locking unit looks like...I didn't see anything that looked like such a device. With the trunk open I can push the key fob lock/unlock button and hear the noise of the unit, it runs for quite a while before it stops. I'm not sure where to go next, so any advice is apprecated. Thank You.
Re: I would think each door lock will have it's own hose...?
I would think each door lock would have it's own vacuum hose. Why would Audi use vacuum instead of just an electric solenoid at each lock - which would be much simpler? This system seems overly complicated for it's actual function. Just my 2-cents and probably not even worth that.
