Yes, and I worry that nobody will really know what parts will be sought after until after they discover that they don't have them in stock and have to order them. I'm suspecting it's the same as some of the other Mercedes cars since they tend to use just two or three different sensors on the bulk of their models, but I also fear that they won't have a clue as to which one it is, but then I've never had any reason to do business with Mercedes until NOW. A part number would help me find out, so keep me in mind and thanks for the super fast response. If others within the Smart family were as fast, there would be a lot less frustrated people.
