I have a 04 plate E270 and am concerned at the lack of mileage I am getting between services. When I picked it up from the dealership I got 12k before I had to get a C service. Now have to get another service (B) after only another 12k miles. I'm doing 600 - 700 miles a week of pure motorway and averaging over 40mpg so am not "battering" the car. My previous Merc, a 320 CLK used to do approx 18k miles between services. Am i being unreasonable to expect the ASSYT system to give me more than 12k between services?
Thanks
