Passenger side door central locking failed?

Hi folks,

Yesterday I noticed that the central locking on the passenger door of my 2003 Sport coupe has stopped working. I say stopped working but when I lock and unlock the car with the key I can hear the mechanism moving inside the door itself but the stud on the door sill won't go up or down so the handle won't open it from the outside. I can pull the lever on the inside to open it (one pull lifts the stud then the 2nd pull opens the door as per usual BMW behaviour).

Anyone got an idea where to start with this?

Cheers!

Replace the door lock actuator. You can find the part number of the actuator you need here www.bmwgm5.com/e46_actuator.htm

It could be the GM5/GMV module. www.bmwgm5.com

From the symptoms the OP described and based on the body style of the car, it's most likely not the general module. It's most likely the actuator.

I had a problem where I could open the door from the inside, but it wouldn't open from the outside. This thread fixed my problem:

Since the repair involves only a zip tie you may want to try this first.

Thanks guys.

I'll give the zip tie a go in a couple of weeks as my car is having bodywork repairs done shortly (painful mistake pulling out of the driveway and scraping the pas side skirt+trim and ripping the trim off!!) and if that doesn't sort it I'll give the actuator a look. I didn't think it was the GM5 as all other locks work fine, it's just the passenger door.

Actually, choxor, when you had the problem, it seems like in that thread your handle was not working so doe sthat mean when you used the fob that the locking stud on the door went up and down? Because on mine it isn't going up or down but pulling the handle makes it go up and down and thus being able to open the door.

Here's a video:



I've also got an update on the symptoms.

1: The passenger door stud on the inside of the car DOES go down with central locking, this locks the car.
2: The stud does not go back up with central locking so the door can only be opened from the inside pulling the handle twice. This indicates the locking mechanism and deadbolt is working so the fault is with the stud/that area.

It was the actuator

Bought one for 55 and spent a weekend afternoon fitting it. Such a pain in the arse to insert and remove through such tight spaces but alas, it is done and my central locking works again \0/

Glad to hear that the problem is now fixed.

55 ($84 USD) for an actuator is really cheap. Did you buy a used one from a breaker? A new one should be > $110 USD. I do not recommend using used coupe actuators. I have argued with too many people that the problem has got to be a bad actuator after they replaced with a used one.
