If your locking system is not functioning ,and usually the power windows and alarm are all linked together, powered by one small fuse witch is located just above the fuse / relay panel very well hidden and hard to find , it will not be shown in the directory panel ., hope this helps ,thanks Louis
The BMW 518 central locking relay switch is located beneath the dashboard. The central locking relay switch will be on the drivers side of the dashboard.
Relays are on the circuit board in the pump unit.This is located in a foam case in the boot right hand side.Usually changed as a complete unit.
The central locking relay is attached to the ECU, fitted behind the right (EU) back passenger side panel.
negative triggering relay.

Hi, problem with alarm and central locking and power windows on 93 94 Corrado is often caused by a fuse located abovethe fuse and relay panel ,very well hidden , cheers
They are at the back behind the ashtray, look in the gap at the top of the fuses.
There are 4 central locking relays on this car. In one of the engine bay fuse boxes, the one whcih contains the multi fuction module. There are six slots above this, 4 of them contain the central locking relays. Good luck....
inside of the driver side door
in the fuse box under the bonnet its a 15amp blue.
Lower right relay. Labeled 167 from the factory.
If the car has an alarm system or remote locking (Key fob) the locking control box is behind the side trim in the (UK) passenger footwell, if there is no alarm there is no relay box the system works off the door being locked and it sends a lock command to the other door
