I have a '98 SL500. At the end of my warranty period and after numerous times to the dealer for correction, I was told that what was happening with my car was "characteristic of the '98 119 motor with the ME fuel system. No correction at this time." Now I'm trying to give the benefit of the doubt to MB, but my car runs rough when cold and bogs down when coming to a stop. I don't feel that this is a "characteristic" as much as it is a problem . After talking to the MB Regional rep, I am now out in the cold as far as a solution, I don't know if I'll be notified in the future of an MB fix, and it seems like MB (through their rep) have kissed me off. Needless to say, I didn't expect this from a company like this.....any suggestions? Thanks
