Hello...Thanks for the reply...My 300D does not have a VCV at all and the car seems to be all original...I have a 1980 240D that has all the vacuum stuff...Sam & myself have been through this stuff time and again....
Was there a problem with your car or were you just trying to find out if these were set up like this from the factory...?.......Cheers!...kevin
