I don't know the W116 but diagnosing 123/126 model vacuum is not hard. Miti Vac, golf tees, vacuum diagram, and a short piece of rubber hose is all that's needed. Access to all key junctions was under the passenger floor mat. But even before that, visually inspect the lines in the engine compartment. I had a possum that took shelter there (W126) but disconnected several vacuum connections.

Had to pop the hood and use the stop lever to shut off the engine. Door locks don't work either. Everything was fine the last time I drove the car a few hours prior. Probably not going to mess with it much today but guess I need to find the mity-vac and see what's going on. The passenger door lock has been misbehaving for a while (locks initially but will be unlocked later) but so far that hasn't affected the engine stop.
