What is Service F???
 

Hi Guys, new here... Need some advice what is Service F. My 2008 E350 4matic is due for Service F in 25 days.. Just checking in advance.. just wondering what needs to be done in service F.. Hoping to hear from you.

Any ideas? Thanks

Hi, I think this means that you have waited as long as you should to complete a service. I noticed this on my 2005: first it said Service b due, then it started c, d, but I never made it to F. I changed the oil and filter and reset the service system. It rates you A through F as you wait after it gives you notice a service is due. The services are described in the manual, but I can't quote it; my manual is over 600 pages. Like one for an airliner.Note I might be wrong, but this is what I think it means.

Thanks for the info.. actually i'm done with service d already.. and it shows that my next service will be F which i will be due in 2 weeks..

I believe I read service F is an oil change and a new cabin air filter.
