Help please – a few questions on servicing. What is a B service and what is a C service? Is B the intermediate (i.e. oil change) and C the fuller service? And what would an A be and is there a D, E etc? Any idea what they cost from an MB service centre? I think that I saw somewhere that if the car covered high mileages on say motorways, the car would recognise this and omit the B service – and the C service might only be needed around 15-17k miles. I bought my E220 CDI with 5K miles in May – and the dash told me I needed a C service in another 7.5k miles. (So 12.5k miles) Now with another 5K miles covered in less than two months, it is telling me the same – i.e. C service needed in 2.5k miles? Should this not have moved back? Any finally – the service book was missing – so the dealer sent me a new one – but rather than saw A, B, C etc services it refers to 1,2,3 etc services. Have they sent me the right book??
