If it wont hold vacuum you'll have to replace it. if its been like this awhile the vanes may be seized. Pull the actuator off and see if the lever moves.

I don't work on enough mercedes to answer, but my tech service had real good info on this one.. We were able to diagnose it in a reasonable time. Parts cost on mercedes is a little ridiculous.
