Mines the same whatever MAF. I,ve tried at least 4 different ones. Went Merc. as in Pierburg MAF???? which one and how much??? (Note I went Merc once....a 1974 200D was that car slow....but when you closed the door....it felt like you were inside a Cheiftain Tank, it was solidly built and it must have impressed me because I bought very few petrol cars after that.
yes, I'm talkin pierburg maf, if you do a serach there's all the info you need,,, also in the tdifaq IIRC,,, I'd never go merc, I hate'em,,, big engines, small power [apart for the amg series of course], cost a heck and the quality at the beginning of the 00's went down a lot,,, everybody was complaining,,, besides they're the only company who screwed up on a car chassis [two times: on the class A and on the smart, which is not so smart actually] which is not exactly as unimportant as say a wiper,,,
besides this, there's the image people who buy mercs have here in italy,,,
genghisackroyd, I think, as with everything, that you need to do this payin attention to a certain number of things,,, stew has your same engine and he's had no prob and he uses the stuff since years now,,,
