My bmw will not start when the central locking fails

i recently replaced the battery in my 2006 X5 diesel, now the central locking is not working, I am in a remote location and not able to attend a BMW dealer, is there anyway I can resent the central locking. Cheers allen

This is a very common malfunction in our cars, often due to a faulty/failing fuel door actuator. You can pull the fuse for it (I forget the # in the trunk fuse array but it's pretty easy to google and find out) or, easier, disconnect the actuator plug (right side of trunk above battery, clearly visible coming from behind the fuel door.) If you disconnect this and the problem goes away, then it is the cause. Just leave it disconnected, the only thing it will affect is the fuel door locking when the central locking is engaged. (If you're worried about syphoning then you can pay to have it replaced or DIY)

hi

there is a motor placed inside the doors for the operation of the central lockin system. when you open the door by key this motos is activated and all door locks are released. your problem may because of this motor is failed.

cause of the failure
1.the wire going to the motor may be chopped off.
2.the junction box connecting the wires may be damaged.
3.fuse may be blown out.
4.motor itsef damaged.

so please check weather power is coming to the motor using multi meter. if the power is not coming to it then the problem is with the wires. if the power is coming to it then problem is with the motor.

i suggest you to take to BMW because you need to remove the door pannel its better if they do it.


please vote me if my answer was useful to you.

I'm having the same problem have you fixed yours?

Providing central locking works when you insert key in lock,try programming keys
Enter car make sure all doors/windows are shut
Switch ignition on and off,remove key
PRESS AND HOLD UNLOCK BUTTON ON KEY
Press lock button on key 3 times whithin 10 seconds and release unlock
Central locking will lock/unlock rapidly to confirm reset
If your key is the type with bmw logo in the middle battery replacement is not possible,as it charges as you drive

insert the key into the drivers side or passender side front door, twist the key and pull open on the handle at the same time and the door will open. It might take a few times to get it, but this does work, source BMW AG Munich.

Hi Craig,
I'm running a E34 Tds Touring with a similar problem, my rear doors and tailgate have dropped of the central locking circuit.
I have been told it is the Central locking Module a large black box under the dash that is faulty, apparently a common problem.
Hope this points you in the right direction,
Please remember to rate my effort!

I have the same problem - Drivers door windows wing mirrors and drivers door lock not working also air bag light on. The car has been to a BMW specialist for over a week as the drivers door dead locked.
The mechanic used his diagnostic gadget which showed a problem with the drivers door. All other doors windows locks work except drivers door. Has check the power supply to the drivers door switch all ok. Is the problem with this internal window control switch and how does this affect the drivers door lock?
Please Please help

you can take the fuse out from under ther bonnet and open and close the doors manually(boot may not open though), the fault is with one of the locking mechenisms in any door

with any BMW they have their problems, one is the central locking/immobilizer, the central locking is linked into the immobilizer and vice versa, the immobilizer takes it signal to disarm from the central locking and the ignition key ring. (chip in the key) if one of these starts to play up it has loads of consequences this being one of them. they all need to work together for the system to work properly. you would need to read the alarm and immobiliser codes using an ob2 tool that can detect them, and find the fault some problems it can be the drivers door sensor in the lock this is the main door as its drivers side and it controls all other doors on the central locking. if the switch is worn in any of it movements the system will not know the door has been opened, this does not work on the interior light as that is a switch in the door frame. the door lock is lock unlock and deadlock with key with remote fob its also arm disarm alarm and immobiliser. i have seen in some models there is a sensor auto lock so when you walk away with the key the doors lock automatically all lease parts work together. any one having a problem can cause no signal to be sent to the others in the system to start engine .
