I have a vacuum problem in this car. The engine will only shut off when drivers door is locked.

If it is a W123 as I suggested in the other post you could apply another vacuum source to the Door Lock Circuit like a Air Conditioning Vacuum pump or you could pull a Vehicle with a Gasoline Engine next to your Mercedes and run a vacuum line from an intake manifold source of vacuum. That would be the Vacuum Supply.
Also the Vacuum Lines are Color Coded. You can access the Vacuum lines by removing the Plastic Piece at below the Door that holds the Carpet down and peel back the Carpet and that exposes the Vacuum lines and their rubber connections.
If you get the color codes of the Vacuum Tubings from another thread you can isolate the one going back to the Trunk.
