Luggage Compartment Lock Cylinder (Except E53/E39 Wagon)

The vehicle can be locked/ unlocked (prior to 2000 MY) from the luggage compartment lock cylinder. The lock/unlock micro switch inputs are processed in the GM III and the locking commands are carried out.

The signal is passed over the P-Bus to the door modules to lock/unlock the front doors and the GM III locks the rear doors and fuel filler flap.

All door actuators are placed in the double lock position. Removing the key in the horizontal position will activate the valet mode and prevent the valet key from opening the luggage compartment.
