Ok, some of you maybe familiar with my ongoing C107 diesel project. Basically I bought the car with the OM603 engine and box froma W124 fitted but by no means fettled, I need your help with this one! The gearchange is very harsh and so i have gone to check vacuum to the box and found this on the modulator valve. The supply to the valve is ok but what i assume is the output side with the green filter goes nowhere and is simply blanked, what is connected to the box is the bottom one that goes into the valve body, I know it is wrong but has anyone any clue as to what should be connected there? Your help would be really appreciated!
