Hi All,
I've a '91 300d 2.5t and have been having problems with vacuum. There seems to be a leak around both of the change over valves, one goes to the ERG and the other air pressure control in the intake. What I need to know is if the those valves should hold vacuum or bleed off? All the hoses have been replaced and tested beyond these two units so reasonable sure that this is the area.

Thanks
Rob
BTW Love this site :)
