my ml320 died 3 weeks ago, literally died. its still in the shop and after replacing the extended activity module, and the all activity module the thing still won't start! ($800+$800+6x$140/hr!!!). now they tell me they need 3 or 4 more days and have to replace the engine's cpu and if that fixes it they may be able to put back the original eam and aam. guy says he's never seen this before. 2002 ml320 bought with 95k and dealer maintained (the dealer that hias it now). are these guys screwing with me or did i just buy a lemon? looking at 4k + and a month with no car to get it back!! i will be driving it to the next lot and trading in for a domestic ride. any advice????? please help!
