Do you have any vacuum left in the door locks or the brake booster?

It sounds like a vaccum pump diaphram tear which has happened with both of the W115's I have owned. It will smoke like crazy and even worse when you accelerate or decelerate in gear causing a bump in the manifold vacuum causing a huge smokescreen behind you evidenced by the honking and finger gestures of the people behind you.
