Hello dear forenuser! With my driver’s door, the central locking system could not be opened manually via the radio remote control or via another lock, i.e. passenger door or trunk. Everything opened only with a key over the driver’s door. So I dismantled the door panel and quickly found it. The actuation of the actuator had been checked out. See photo-red circle! The green circle is the actuation to the door button. As can be seen there is a plastic guide between the “stick” and the plastic holder that connects both parts. If you look at the part with the red circle (from the actuator), you can see that this plastic part is missing there. Therefore, the actuation bar (red circle) always slips out and logically does not open the door.Comfortably, the matall operation does not have any resistance in the plastic guide at all. It is not attached! Now my request to you:Who can tell me how the original looks or how I can fix it?
