Hi again,
I'm having another problem now.
As I not sure if all the central locking problems would be fixed with a software update to the BCM, I leave here an explanation of what is happening to mine.

When the speed reaches +- 25mph all the doors are closed, so far so good.

If, before leaving the car, I open all doors using the door locking button, central locker keeps working fine.

If I open, while locked, any door (except the drivers door), central locker keeps working fine.

But if I open the drivers door, while locked, I will have to reset again the BCM.

Is this a software problem, or the lock actuator on the drivers door?

Many thanks
