If you own a Mercedes-Benz, you’ve probably heard of Service A and Service B. These two maintenance schedules are part of Mercedes’ Flexible Service System, designed to keep your vehicle performing at its best while extending its lifespan. While they share some similarities, there are important differences in what each service includes, how often they’re needed, and why following the schedule is crucial for your car’s health.
The Mercedes Service Schedule
Mercedes vehicles use an onboard computer to track mileage and time, alerting you when it’s time for either Service A or Service B. This schedule isn’t just about changing oil—it’s a comprehensive approach to preventative maintenance. By addressing wear and tear before it becomes a problem, these services help prevent breakdowns, maintain resale value, and ensure your car meets factory performance standards.
What Is Mercedes Service A
Service A is the first major service your Mercedes will need, typically performed at around 10,000 miles or one year after purchase, whichever comes first. After that, it’s generally due every 20,000 miles or two years.
Service A includes:
- Synthetic motor oil replacement
- Oil filter replacement
- Fluid level checks and corrections (brake fluid, coolant, windshield washer fluid, and more)
- Tire inflation check and correction
- Brake component inspection
- Resetting the maintenance counter in the vehicle’s computer
The goal of Service A is to perform essential maintenance early on to keep the engine and other systems in top condition.
What Is Mercedes Service B
Service B is more comprehensive and is typically required at around 20,000 miles or two years after purchase, then every 20,000 miles or two years after that. While it includes everything in Service A, it also adds deeper inspections and additional replacements.
Service B includes:
- All Service A tasks
- Cabin air filter replacement
- Brake fluid exchange
- More thorough inspection of vehicle systems and components, including suspension, steering, and undercarriage
Because Service B involves more labor and parts, it takes longer to complete and generally costs more than Service A.
Why the Difference Between the Two
Mercedes structures its maintenance this way to balance efficiency and thoroughness. Service A is a lighter service designed to maintain the vehicle in excellent working order between more in-depth Service B appointments. By alternating between these services, you ensure your car gets frequent attention without over-servicing.
The Benefits of Following the Schedule
Keeping up with the A and B schedule provides several benefits:
- Longer lifespan – Preventive maintenance reduces wear and tear on critical parts.
- Better performance – A well-maintained engine and drivetrain perform more smoothly and efficiently.
- Higher resale value – Service records from a qualified shop show potential buyers that the car has been cared for.
- Reduced risk of breakdowns – Regular inspections catch small problems before they become major repairs.
Customization Based on Driving Habits
Not all drivers use their Mercedes the same way, so the exact timing for Service A and B may vary. Harsh driving conditions—such as extreme heat or cold, heavy stop-and-go traffic, or frequent short trips—can accelerate wear and make earlier service necessary. The onboard computer adjusts recommendations based on your driving patterns, so pay attention to the alerts on your dashboard.
Professional Service
Mercedes vehicles are engineered with advanced technology and precision parts, which means maintenance should be performed by technicians who understand the brand’s specific requirements.
