What this part does
The Door Lock Actuator is an electromechanical assembly mounted inside the door shell that physically engages and disengages the door latch. It operates based on signals received from the vehicle's central locking system, body control module, or the key fob. This unit houses both the latching mechanism that holds the door shut and the electric motor that moves the lock cylinder. When this actuator begins to fail, you will typically notice the door refusing to lock or unlock with the remote, a buzzing noise from inside the door panel, or the door failing to stay latched when closed.

Before you order
These actuators are strictly position-specific (front left, front right, rear left, or rear right). They are also highly dependent on the equipment level of the vehicle it came from. BMW 6 Series models were offered with standard locks as well as the optional Soft Close Automatic (SCA) door feature. An actuator from a soft-close door will not function correctly in a car equipped with standard doors, and the wiring harnesses differ. Verify your vehicle's specific options and compare the electrical connector pins on your original unit before purchasing.
