My A4's front door lock won't unlock any of the doors beyond its own, nor will it turn the alarm off. It will lock the whole car and engage the alarm system. Basically, the front door lock won't do anything beyond its own door when I unlock the car. This is a problem.

Does the front door lock communicate with the central locking system by any means other than the hose? Any ideas on how to diagnose this issue?

I have the door panel off now because my front driver's side window is having issues - just tested the switch and it works fine, sadly. God help me.

Figured I would try to knock both things out at once. Thanks for your help, guys.

 

The lock cylinder must have a wired connection with the central locking system also. I installed a remote start and I used wires in the driver's kick panel for locking and unlocking the doors from the new remote as well as setting the alarm. Pushing the lock button on the inside of the door won't set the alarm so there must be wires on the lock cylinder that tell the central locking system that you turned the key to lock or unlock. The system uses a negative signal to lock and unlock the doors on the wires I used.

 

Hi Guys,

I have a problem of a differnt kind. I have an Audi A4 B5 1995/1996 (i live in germany, cant understand their language yet so posting on English forums :-)).

Driver side door:
When i unlock using the key in the door, only that door opens. But when i get in and shut the door all the doors, gas flap and boot open up. When i lock it, again, using the key in the door, it locks all doors. A few days back it miraculosly let me open all the doors with the key from the driver side door and made me look good in front of this chick i was picking up :-), but now it doenot.

Passenger side door:
Locks/unlocks all the doors and boot and flap.

Remote Lock/unlock:
I have a key with just one button on it, i do not know what it is used for, Locking or unlocking. I changed the batteries but nothing worked. I asked the previous owner and he said he never used it, he always locked and unlocked the doors manually. Its so amazing how some ppl have no curiosity. I called a dealer and he said bring the car over and we will check it out (meaning: We will do nothing and will keep your car for a few days and then give you a 100€ bill), i don't wanna do that.

A little help and guidance will be hugely appreciated..

Regards
Suresh
