I'm sure its different on each motor (240D, 300D, 300D turbo, California emmision, etc) ? This is the first MB diesel I've owned so I'm in no way an expert.

If I ever get the car back from my girlfriend I will put this issue to bed (for this particular engine, anyway). Car is still shifting great.
