yeah i figured out the feul door thing this morning. i did plug the the line to disable the locks and now it shifts a little lower and more consitently but still a bit hard. i think that it might be the modulator valve. does anyone know of other areas besides the locking mechanisms that are more prone to leakage than others and are not essential to have plugged in? i also realized that this car has only 67hp!!!! it moves quite nicely though! every mention that i came across said that this car was too slow for its own good. but if you push it, it goes well. i've actually been speeding more than in my little turbocharged merkur xr4ti. i mean the benz doesn't accelerate like the xr4ti at 70mph but who really neads to accelerate hard at 70 anyway. even if it has a few problems i love my diesel mercedes. now i know why people that own them either sell them for a lot or not at all. this isn't a car i'd like to get rid of either. back to the modulator thoguh, it looks like it is sort of a wingnut type fastener or some odd wrench in the picture that mercedes shop had and under my car. is there any specialized tool that i need to remove it. it looks plastic so i don't want to force it out. if so where could i get one of these whenches and how much? the picture looks like there is a key of some sort. is that a removal tool that is included? also i have heard mentions of some people changine ALDA settings or something is this the cars computer? could i use it to fine tune the transmissions shift points via vacuum? thanks for your time and patience.
bye
