Hi

I'm new in this forum and my native language is not englich. Just to excuse some errors in spelling or wordning.
I have a RRS L320 build 09/2010 with the 3,0 liter Diesel engine (245 HP).
My problem is the central locking thing. If I try to lock the doors, only the door on the rigth side are locked.
The other doors on the left side do not lock.
So I tried to change the Door Module from left to right and then the doors on the left side lock but the doors on the right side no longer are locked.
I also have replace the left side driver door module, but even that did not help.
Anybody an idea where the problem could come from?

Kind regards
Daniel
