Hi all. My 211 E280 CDI showed 4000+ miles to next service (B) Trying to manage my money better; i came up with a cunning plan a couple of months ago... I changed the oil and filter, air filters, and air pipe (includes both MAF sensors). I then started keeping it garaged, to bring out only on the weekends and odd occasions... using my wife's 210 as our daily runner. I was somewhat surprised when today it suddenly said; B service due in 29 days... I thought doing the mini service myself would prolong the time to the next service? I've had the car just over a year and the last service (A) was done about 8 months ago... Wonder what's happened?
