Newish to the forums, but a long-term Merc owner starting with W123, R107, W124, W202 and now on to a S204 I bought a year old last August. Anyway, I object to the servicing interval being time and not mileage based. It was obviously serviced in June last year before being put on sale and I bought it in August with 10,000 on the clock. It now has 17,000 and it is telling me the service is due in 50 days. The 202 was 12,000 miles but adding a litre of oil made that nearer 15,000 and I don't see why it should be less with the newer model. Any way to reset this to get a more realistic service interval? Thanks in advance.
