Boot Central locking problems

[W111nyr]

I have an e30 Baur which has Central locking however only the driver and passenger door works with the key, the boot I have to unlock manually.

Any idea what the problem could be?

Many thanks

Does the fuel flap lock work?

Yes, fuel flap works, only the boot doesn't work

The fuel flap lock motor is on the end of the cable run that controls the locking, so the problem must be either a duff boot lock motor, the motor plug has come adrift, or the linkage between the motor and lock has come adrift. Remove the rear lamp lamp holder assemblies, then the fibre board boot liner panel across the back, and see what's happening.

Many thanks for the advice I will try this week and let you know how I get on.
