The 140 is a whole different beast entirely.
I'll admit, I know very little on the diesel 140's as I have seen VERY few of them, and worked on as many as I can count on one hand. In the trunk is a PSE pump for the central locking as usual, similar to the 126 pumps, but more advanced. I don't believe it controls anything but CL and closing assist (maybe another tech can offer some more insight on this).
Correct me if I'm wrong but that car should have EDC, Electronic Diesel Control. Get the car to a place with an SDS machine (independent MB should have this, as well as a dealer) and they will be able to tell if its a computer issue with the system not actuating the valve or something mechanical.
