Peter,

The reason I was asking about the "Throttle Body" is that I was corresponding by E-mail with another guy that has the Identical car as mine i.e.: a '95 E300 Diesel OM606 Engine, and has had to replace the wiring harness. I also have a problem with the wiring harness that I fixed temporarily but that eventually I also would have to replace.

But back to the "Throttle body". His Mercedes dealer told him that when they replace a wiring harness on that car they usually also replace the "Throttle Body". He chose to have the work done by an Independent Garage that told him that his "Throttle Body was fine and does not need replacement. He went ahead and replaced just the wiring harness.

Hence the reason for my question? The only symptom that I have right now is a slightly elevated idle speed, i.e.: 750-80RPM, when cold and than subsided slightly to around 700-750RPM when the car warms-up.

Not sure if that helps

Phil
