Does anyone have the vacuum diagram for this specific year/model? I searched forum, but am unsure if the one for the diesel would be close enough, I am thinking no.

Any help would be appreciated.

Well, I was referring to the one that works off of the engine, but if the A/C is at all connected to that, then that one as well. Then central locking is in the W124 manual, but it is really the only one that I see in there.

It's under model / engine / intake and exhaust manifold / vacuum system.
