Central lock living its own life

2008 Clubman Cooper D

For the past months my central lock has been acting weird. It started with when unlocking with the remote, all doors unlocked but immediately locked again. Then it has become worse. Now sometimes it will not unlock at all with the remote, so I have to use the key in the door to unlock. Sometimes it will not respond when using the lock/unlock switch in the centerconsole. Sometimes the left of the rear barn doors will stay locked when the rest of the doors are unlocked. When driving, the doors lock and unlock without me doing anything. When parked in the garage with the doors locked, I can occasionally hear a lot of clicking noise from the door locks (but the doors stay locked).

I have searched and read all the threads I can find here on the forum, but I mostly find info from the gen 1 cars. Many of these threads states that there is a "master" central lock in the drivers door that communicate with the rest of the doors, and that the "master" module normally has to be replaced. But I would really like to be more certain that this is the solution before I go ahead and spend the Money to have it replaced.

Any of you experienced anything similar on your gen 2 car?

Appreciate all the help I can get.

Have you had recently any radio communication equipment erected anywhere near to where you park the car, like a phone mast for instance? I know they can sometimes play havoc with the remote control signal to the car depending on the frequency?.
Theres a car park near me where the car will not lock or unlock with the remote in a particular position, as soon as youre up the road everything is fine again.

No radio or electrical mast installation in my neighborhood recently. The problems happens everywhere so I do not think there is external interferrence causing this.

The problem with the gen 1 cars is the microswitches in the door lock actuator go faulty & cause similar problems to what you are having. I would try unplugging your drivers lock actuator & see if the doors carry on locking unlocking when driving

Assuming that the problems go away with the drivers door actuator unplugged, and the problems still exists on the remaining doors, what can then be the source for the problems? Could it be the Body Control Module?

Normally if its the BCU you would most likely be experiencing other problems, I would give it a try it's not costing anything so its got to be worth a shot

Is there a way of unplugging the drivers door actuator from inside the car? Or do have to get access to the actuator itself? Would be nice to avoid to have to take the whole door apart if not necessary.

You will have to take the door panel off to get to it
