Hi, I'm looking for some advice about my 2007 E Class 220 CDI Merc. I was wondering if anybody could tell me what a "C" service consists of? ie: Oil change and what filters need changing and anything else that I might need to do to complete a "C" service. I do all my own servicing/repairs etc but I just don't know what the "C" serice consists of. Any help & advice will be appreciated. Kind regards, Alastair.
