Hello, I have a problem with my rear V50 side door. The central lock no longer speaks to. When opening with the key or the button, you can hear the cracking of a relay in the door, but the locking button does not stir a millimeter. The stupid thing is, I have activated the mechanical child lock mechanism. however, you can only reach it when the door is open again. If I try to open the door from the inside, then the pin goes up, but disappears when releasing again in the sinking. If I hold the button as soon as it is up and then try to open it with the external handle, it doesn’t work either. I found a link here in the forum how to extend the panels. I have done this with success today, too, without breaking anything. Unfortunately, the locking module hides behind the inner cover. this is attached with 8 screws. But I don’t know if you can also use the window lifter for the inside panel. In any case, I have to solve 3 more screws which fix the locking mechanism. But on this side, you can only get the door lock is open.
