Mercedes maintenance schedules confuse a lot of owners. Here is a clear breakdown of what Service A and Service B include and when each is due.
If you drive a Mercedes-Benz, you've seen the "Service A" or "Service B" message pop up on your dashboard. Many owners are confused about what each one includes and why the prices vary so significantly. Here's a clear breakdown.
What Is Service A?
Service A is the lighter of the two scheduled maintenance services. It's typically due at 10,000 miles or 1 year (whichever comes first) after a new vehicle purchase, and then every 20,000 miles or 2 years thereafter.
Service A includes:
- Synthetic motor oil replacement
- Oil filter replacement
- All fluid level checks and corrections
- Tire inflation check
- Brake component inspection
- Reset of maintenance counter
What Is Service B?
Service B is the more comprehensive service, due at 20,000 miles or 2 years after Service A, and every 20,000 miles/2 years after that. It includes everything in Service A plus additional items.
Service B includes everything in Service A, plus:
- Cabin air filter replacement
- Brake fluid exchange
- Dust/combination filter replacement
- Visual inspection of brake pads and rotors with thickness measurements
How Much Should It Cost?
At a Mercedes dealer, Service A typically runs $300–$500 and Service B $600–$900 depending on location and model. At an independent shop with technicians trained on European vehicles, you can expect to pay significantly less for the same quality service and parts.
Can I Skip or Delay Them?
Mercedes-Benz uses 100% synthetic oil with long oil change intervals. Skipping or excessively delaying Service A or B can void your warranty and cause accelerated engine wear. The maintenance reminder system is calibrated to your specific driving conditions — trust it.
