Mercedes uses two main service schedules — **A Service** and **B Service**. Knowing the difference helps you avoid unnecessary costs and keep your Mercedes running exactly as intended.
What Is a Mercedes A Service?
The A Service is your routine, lighter maintenance service.
A Service Includes:
- Engine oil & filter replacement
- Fluid level checks
- Service indicator reset
- Visual brake inspection
- Tyre check & pressure adjustment
Interval: Every 10,000–15,000 km or 12 months

What Is a Mercedes B Service?
The B Service is more comprehensive and less frequent.
B Service Includes:
- All A Service items
- Cabin filter replacement
- Detailed brake system check
- Suspension & steering inspection
- Diagnostic scan & fault reset
Interval: Every 20,000–30,000 km or 24 months
Cost: $399–$699+
