HAS ANYONE thought that the Benz may not be the problem. Lets face it.The mechanics in U.S usually don't know what they are doing. I have deal with not only with Mercedes mechanics but also Volvo, Wv authorized dealership mechanics. Believe me, the mechanics don't know what they are doing. After the second visit, with new parts installed where seems to be the problem. Have anyone though that the part may not be instaled properly or the guy had no idea of what he was doing. I do have Ml 320 with no much elecronics and so far no problems.
