Mercedes Vacuum Pressure Converter
Hi: Can someone enlighten me on how to properly test the pressure converter on an '85 300. Before it's last trip to have the swaybar replaced everything worked like new, now I have no turbo, it won't stop when I turn off the key and it shifts really bad.
Smells like a vacuum line somewhere was hooked up wrong. Anyways, in trying to find the vac problem I noticed that the EGR line was plugged going into the pressure converter. I tested the EGR valve and it appears to be bad (155K miles)unplugging or plugging the line doesn't seem to make any differnce.

PS: I bought the mercedes CD from the parts shop, but I can't find anything on how to test the pressure converter. I unplugged the EGR line, removed the EGR valve and cleaned it throughly with Brake cleaner. It was really clogged with a sludge like substance.almost like soft tar. I took almost a teqaspoon ful out of the bottom of the EGR valve and from the manifold where the EGR attatched. Everything I could see inside the manifold look pretty clean. I still haven't been able to test the pressure converter, and have no idea what it really does, but the car is running great now so I'll believe that the pressure converter is doing its job. Thanks for the help.
