Also does the ratio vary for the 4000 CDI gearing for different years?
thanks,

Sorry, not here often, just saw your post. If you are still on here, as far as I know, the 400CDI only has one set of ratios. From memory, my diffs came from Germany.
My earlier post names the shop. Renntech, very well know Mercedes tuner in south Florida. Hartmut Feyhl is the owner, trained at AMG in Germany many years ago.
Hartmut did not do the reprogramming, one of the young computer savvy techs did. Nothing came out of the car, all done through programming. I believe it was just the transmission computer (TCU).
