SOURCE: central locking does not work on my BMW 320D SE model

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.

hi this a camshaft position sensor fault, i think the reason for the cut out is because the vehicle cannot tell what position the camshaft is in relation to the pistons, if it all goes out of sync it will cut out to stop damage happening, you will have to replace the sensor, this is located at the top left hand side of the engine/motor you should see it at the front...hope this helps
