Does anyone have a link to, or information about what is included in the second "B" service at 40K miles? I'm not finding anything definitive. MB booked my appointment for B service with brake flush. I'm interested to find out if the air filters get changed at this service interval.

 

Quick google search: https://www.fjmercedes.com/mercedes-...rvice-a-and-b/ This is consistent with everything I've seen.
You can also reference your maintenance schedule booklet. Electronic copy is available on mercededme https://www.mbusa.com/mercedesme

 

Thanks DBMC! I guess I'll have to request the air filter change...
