2006 E55 - strange door lock problem

I am having an issue with the passenger side front/rear locks ONLY when pulling away from stop. If I lock with the remote, all 4 lock. If I drive away, the driver's side locks and the passenger side locks/unlocks twice and remains unlocked.

Any ideas?

CTS-V ///

Check the door pin switch on the passenger side.

Car free at the moment

Common problem. It's the door lock actuator. Not sure if the actuator can be repaired, I had warranty so just had the dealer replace it. I have heard the problem described as Mercedes machine gun door locks. Try googling to see if anyone has posted a repair procedure.

Found another thread here. Simple as spraying the boot that the lock shaft passes through with some silicone to keep if from dragging and it's working perfectly again.
