The F actually signals the importance of the maintenance required and it's a critical one: change all filters and fluids (engine, brake, steering, transmission) , even the rear axle and especially the automatic transmission filter and fluid (don't believe the 100,000 mile service) or you better start saving $5,000 for a rebuilt tranny. Change all belts and save the old belts as a backup. Be sure to change the Cabin Charcoal (Carbon) air filter and the spark plugs too. Also all the suspension parts will be inspected thoroughly. Service F is a 6 hour service
To reset it turn on the ignition and get to the service warning. Hold the reset button for a few seconds and 'service menu' will pop up. In there just select the oil and confirm the reset.
In 2003 Mercedes Benz launched FSS Plus and service went from easily understandable to ultra confusing. Service F means your E class has a list of maintenance it needs done. What that specifically is, I cannot tell you without seeing the car. I would need to connect the car to a diagnostic system and "read" what service the vehicle is calling for. A good rule of thumb is however, for each increase in letter value, you can assume one hour of technician labor. In this case F=6 approx hours of work. This does not include parts, but is designed as a time estimate. (See Below)
Svc Time it takes
A about 1 hr I have not seen a car beyond Service H. I worked in a Mercedes Shop for over 6 years, and have been present for all E-class redesigns. I recommend to have your car checked by Mercedes Mechanics. It is better that way than to reset the maintenance code.
B about 2 hrs
C about 3 hrs
D about 4 hrs
E about 5 hrs
F about 6 hrs
G about 7 hrs
H about 8 hrs

Already knew the data. Was quoted 400 for D, I am assuming 600 doe F. That was with all fluids etc.... Is there anyway to reset the system and just take it in for the D. Again what does F maintenance do?
