What Is Performed During Service B at a Mercedes-Benz Dealership?
Service B is the larger of the two scheduled services in the Mercedes-Benz Flexible Service System, and it alternates with Service A. A typical Service B includes:
- Oil change with an approved synthetic oil such as Mobil 1
- Genuine fleece oil filter (see here)
- Brake fluid change
- Cabin air filter replacement
- Engine air filter replacement
- Fluid level checks and top off: coolant, brake fluid, power steering, washer fluid, and AdBlue on diesel models
- Tire inspection and rotation, with tread depth and pressure checks
- Lubrication of hood hinges, striker plates, lock cylinders and the sunroof
- Brake pad thickness and condition check
- Heating and ventilation inspection
- Function checks of the lamps, headlights, seat belts, and windshield wipers and washers
- Ball joint and steering system check
- Poly V-belt inspection
- Starting and charging system inspection
- Flexible service system counter reset
This list may not be complete and can vary between dealerships. Additional maintenance, such as air filter replacement, lubrication and tire rotation, depends on the vehicle’s model, condition and maintenance schedule. Always follow the owner’s manual. If you do the oil change yourself, our DIY oil change guide walks through it.
What Is the Cost of Service B at a Mercedes-Benz Dealership?
The price varies greatly by location and model, but the reported quotes for this service range from $280 to $540.
How Often Should You Perform Service B on a Mercedes-Benz?
For many US market models, the first Service B is due at approximately 20,000 miles or one year after the previous service, with later intervals generally around 20,000 miles or two years. Follow your vehicle’s maintenance schedule; our maintenance by mileage and year guide lays out the rest of the schedule.
Doing Service B Yourself
Two jobs on the list need more than hand tools. The service counter has to be reset after the work, which our guide to resetting the service reminder covers, and a scan is the quickest way to see what the car has logged since the last service. A Mercedes capable scanner such as the UCAN-II Pro reads stored fault codes from every module, so a weak battery, a charging fault or a brake wear warning shows up while the car is already on your ramps.

Before you buy parts, scan every control module, not just the engine. It shows the root fault behind the warning lights and tells you whether the problem is still active. See how to do a full health check.
