So this seems like a silly question but I am rightly confused. Owners manual on S212 E350 says fuel filter needs changing around now. The service history from MB dealer has a comment of "declined fuel filter change", which makes it sound like customer decided against a replacement. Online car parts companies don't list the E350 CGI in the compatibility lists and MB Newcastle have said "none fitted". WIS shows part A2214700259 for the M272 but when I filter by my model / engine on online stores, nothing is returned? Surely all cars needs a fuel filter?
