BMW E32 central locking faults

Why do the E32 doors unlock by themselves even though the car is locked?
Usually one of the lock motors has stuck or shifted. The cause can be the driver's or passenger's door motor, moisture in the boot lock motor, or a stuck locking lever. Check that the locking linkage moves freely.
Why does the E32 door lock again as soon as I unlock it?
The boot lock motor can get stuck or end up in the wrong position, so the doors unlock and lock again straight away. The wires to the boot can also bend and break over time or touch the body. Also check that the key has not been turned open in the lock by force.
What else can mess up the E32 central locking?
An aftermarket extra lock can jam and prevent the original from working. Faults can also be caused by a faulty control unit, broken wires in the driver's door grommet and an oxidised wiring harness connection. The boot lock can short-circuit against its chrome housing.
