Driver side door lock will not work with remote or interior switches. Has to be worked manually. All other locks work as they should via remote and front door switches. The manual switch flexes when triggered with the remote or interior switches but does not turn over.. thanks, Bert

no you needs a new lock actuator on that door its about $90 installed,
all the locks are on same circuit . sorry about the bad news :(

Since the driver's door gets the most use, and all circuits run through the master switch, check driver's door first and check the wiring at the hinge area for breaks.

relays on comfort modules are faulty, you can change comfort module or just replace the relays if you are experienced with.

This is all the Bentley shows:

Note:

it is not the actuators, try a different remote, you may have an issue with the car security system/body computer not functioning on the unlock driver door command, one press of remote is unlock driver door and 2 presses is unlock the other doors.

this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.

Sounds like your remote reciever unit has gone bad.

The switch is finding its ground thru the interior light switch. Your problem is most likely a broken wire in side the rubber boot that goes from the door to the body near the door hindges.

Probably the door actuator - a part inside the door that activates the lock, particularly if neither the interior lock switch or the remote do not lock the door.  Once the doors lock the horn will beep again - the lack of beep indicates the vehicle is not secure.

If remote locks and unlocks driver door but does not unlock passenger doors,then follow the advice above:
Get in the car using the key to unlock the doors. From the passenger side lock and unlock your doors using the button on the passenger door. Get out and the remote should now unlock all the doors with 2 presses.
Worked perfectly for me after several other suggestions (and dealer) failed.
