Service B in 26 days

I am getting a service message that says “Service B in 26 days”. What does this indicate?

I went in to the service message thing and only managed to reset the mileage counter from my last oil change. Nevertheless it still has the day to service indicator message.

I’m guessing it is for brake fluid flush or something else that is time dependent rather than mileage dependent but I can’t figure it out.

Thank you,
Peter

Service B is recommended every 20000 miles or 12 months after complited service A interval.

B includes:
  • Mercedes-Benz Synthetic Motor Oil Replacement
  • Oil Filter Replacement with Genuine Mercedes-Benz Fleece Filter
  • Replacement of cabin dust/combination filter
  • Tire inflation check and correction
  • Brake component inspection
  • Fluid level checks and correction
  • Maintenance counter reset
  • Brake fluid exchange

Quick google search gave that information.

Maybe reset does not hold if done too early? Do another reset in 27 days. IDK

If you are in the menus go to the Positions tab and it will show the services by #, then compare what is in the manual for that service.

I'll try it.

FWIW, the Message says "Service D in 26 days" not Service B, my memory lapsed.

Bizarre! That kind of worked.

I followed the first set of instructions past the point where the voltage is displayed and then got a message saying service in 26 days. Then by doing one of the buttons S110S3 or similar, I got to a reset menu and reqested a full reset confirmation. I did this and now it says I have 13000 miles and 365 days to next service.

I’ve had this car for 20 years and don’t recall ever seeing this.

According to the manual in a W211 the "D" represents the amount of time it should take to service the car for that upcoming service.

Ha ha! 3-1/2 hours!

You can double that when working in a small garage. At least the brake flush went really smoothly. Also on inspection, I found a decomposed shift linkage bushing. The dealer had it in stock for $7.51 including tax, and it went on in five minutes (not counting driving to the dealer).

Thanks again.
Peter
