If you have your car serviced at a good MB independent, they should be able to reset the system. If you take your car to Goofy Lube, however, they won't have a clue. Also have you seen the quality of filters that they use at most of those Goofy Lube places. I woudn't put one on my car. I spun one off a W201 the other day to get to something. It hab about half the stuff inside and half the weight of an OEM and it was oil saturated and the OEM was dry.
