Here's the long answer: "ANSWER by ZeeTech on February 05, 2011 There is not really a service F, it means a time interval when you need the get the service A or B. Here is the explanation from the MB manual: Maintenance System: FSS (Flexible Service System) Model Years: MY1998 - MY2004 Models: 129, 140, 163, 170, 202, 203, 208, 209, 210, 215, 220, 230, 463 With the FSS maintenance system there is a minor or major service designated as "A" or "B" respectively. If the last service performed was an A-service, than the next service will be a B-service. For subsequent services; if the distance driven since the last B-service is less (<) than 14,000 miles, than an A-service should be performed. Consequently; if the distance driven since the last B-service is greater or equal (=) than 14,000 miles, than another B-service should be performed. Service intervals are based on oil quality, which is determined by the vehicle's oil quality sensor. MY1998 - MY1999 the instrument cluster service reminder displays one wrench. Any additional work to the respective A or B service scope is calculated using the maintenance sheet. If you need a good shop in your area I can suggest a good one with excellent feedbacks. Zee" Short answer: you are overdue by 24 days on either an A or B service and it would take an MB mechanic about 2.5 hours to do. Sounds like the service minder has never been reset, so service the car based on mileage and get back on track. When in doubt, do more.
