Hello, I have an issue with my 2010 BMW F11 driver's door locking. When I press the lock button on the key fob it locks all doors except driver's door. I can lock driver's door manually from the inside and also from the outside with the key. When I do that and press the unlock button on the key fob it then unlocks all doors like it should.
I have read few threads where people suggest that the door locking actuator may be faulty. I tried to change it to a new one but that did not solve the problem.
I tried to apply 12 volts directly to both new and old actuators, both of them work so I guess that the problem is not related to them.
I checked all the fuses from fuse diagram which are related to locking. (fuses: 2, 8, 14, 15, 32, 38, 56, 58, 110, 143, 144, 149 and 152) and I did not found any burnt ones.


Then I tried to check the voltage in the actuator plug, so when I press the unlock button it gives a -12V pulse and when I press the lock button it only gives 12V pulse sometimes. (I think that when triggering locking it should give +12V and when unlocking -12V, I do not know that for sure).

Do you have any suggestions what should I look next?
Thank you.

Problem solved: It was a faulty JBE (JBBF) module. I changed it, coded it with e-sys and everything now works perfectly. Case closed
