1387961 BMW E38 E39 ZV Central Locking Module – OEM Used & Tested

Description

This BMW central locking module is a genuine OEM body electronics component for BMW E38 and E39 models. Primary OEM number 1387961. It is designed to control the central locking system, known in BMW terminology as ZV (Zentralverriegelung), by managing the lock and unlock signals that are sent to the door, trunk and fuel filler flap actuators throughout the vehicle.

Its job is to receive lock and unlock commands from the key, the door lock switches and the interior controls, process them and drive the actuator motors in every door, the trunk lid and the fuel filler flap. It also supports the double lock and anti-theft functions where fitted. A properly working central locking module supports reliable locking, correct unlocking and consistent operation of the complete body electronics system in these 7 Series and 5 Series models.

Common signs of a faulty unit include doors that do not lock or unlock together, one or more actuators not responding, the trunk or fuel flap not releasing, intermittent locking after the vehicle has been parked for some time, or the system working only from the key and not from the interior switches. When the module fails, the central locking system may operate erratically, drain the battery or leave the vehicle unsecured.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 1387961 before ordering. Professional installation is recommended, and diagnostic testing or system adaptation should be checked where applicable.
