CLK doorlock

[Mercfunder]

Hi

I have a 2004 CLK 320 (W209).
Yesterday the pin on the doorlock pin on the passenger side has started jiggling up and down a couple of times when the remote is pliped.
The door lock still functions OK, locking and unlocking.
Any ideas what is causing this, is it damp on a switch?
Any help appreciated.

Common fault apparently, the bit inside the door needs replaced, can't remember the name though. door controller?
