If you own a Mercedes-Benz in Palatine or the Northwest Chicago suburbs, you’ve seen the “Service A” and “Service B” reminders appear on your dashboard. Mercedes dealers charge $300–$700 for these services. At Wizard Werks, we perform the same services at a significantly lower price — with the same quality fluids and parts. Here’s what each service actually includes, and when you need it.
What Is Mercedes Service A?
Service A is the lighter of the two scheduled services, typically due at 10,000 miles or 1 year (whichever comes first). It includes:
- Synthetic motor oil change (Mercedes-approved 229.5 or 229.51 spec)
- Oil filter replacement
- All fluid level checks and corrections
- Tire inflation check
- Brake component inspection
- Reset of the service indicator/ASSYST system
Cost at Mercedes dealership: $250–$400
Cost at Wizard Werks: Significantly less with same-spec synthetic oil
What Is Mercedes Service B?
Service B is the more comprehensive service, due approximately every 20,000 miles or 2 years. It includes everything in Service A plus:
- Cabin air filter (microfilter) replacement
- Brake fluid replacement
- Spark plug replacement (if applicable to interval)
- Fuel filter inspection/replacement (diesel models)
- Dust/combination filter replacement
- Comprehensive multi-point inspection
- ASSYST system reset
Cost at Mercedes dealership: $500–$700+
Cost at Wizard Werks: Significantly less with no compromise on parts quality
Can Any Shop Reset the Mercedes Service Indicator?
Yes — but only if they have the right diagnostic equipment. Wizard Werks uses professional-grade Mercedes-compatible scan tools to properly reset the ASSYST/MBSA service indicator after every service. You won’t leave with a warning light still on.
