Well .... I've got a relatively good OBDII scanner ... that's how I read the codes and how I've been turning them off. I learned by going once to a dealership and being charged $75 ... never again. Many of the OBDII codes are generic. I would imagine, though I am not certain; even the code readers MB dealerships use would probably give them the same code and explanation for my type and scope of issue. You really don't need "MB software," and I'm not sure there is specific software that MB uses .. though they do have some special scanners for some MB-unique systems, e.g., SRS. Any OBDII scanner with erase capability will erase/reset the code memory for the generic codes like P0170. I'm sure I've far exceeded my scope of knowledge here ... so, please don't jump on me for trying -- thanks -
