I have found answers to a number of questions though this forum both from Techs and other Mercedes-Benz owners. In fact I enjoy the postings for all types of problems even those not applicable to my vehicle. Many topics can also be researched by doing a search of prior postings. You might try to search feature for your answer. What is the question you have? Remember the Techs and the 3000+ members of this site offer "free of charge" the benefit of their experience. Perhaps your question was not clearly stated, did not give enough information, or just simply did not attract enough attention. If first you don't get a response, search and then try again.
