Key Takeaways

• Service A is the smaller, more basic maintenance package, typically due after the first year or 20,000 km. It includes an oil change, oil filter replacement, and various inspections.
• Service B is a more comprehensive service, due about a year after Service A. It includes all Service A tasks plus a cabin air filter replacement, brake fluid exchange, and more in-depth inspections.
• The Mercedes Service B cost is higher than Service A due to the additional labour and parts involved.
• Your vehicle’s Flexible Service System (FSS) uses sensors to monitor your driving habits and vehicle condition to determine precisely when each service is needed.
• Using an independent specialist like Boosted Auto Works for your Mercedes Service A in Markham can provide dealership-level expertise without the premium price tag.

Decoding Your Mercedes-Benz: A Complete Guide to Service A & B

Owning a Mercedes-Benz is an investment in world-class engineering and luxury. To protect that investment, adhering to the manufacturer’s recommended maintenance schedule is critical. The foundation of this schedule is the alternating Service A and Service B appointments. Understanding these services is the key to ensuring your vehicle’s longevity, performance, and safety.

What is the Mercedes-Benz Flexible Service System (FSS)?

Before diving into the specifics of each service, it’s important to understand the system that triggers them. Modern Mercedes-Benz vehicles are equipped with a sophisticated Flexible Service System (FSS). This isn’t just a simple mileage counter. The FSS uses a variety of sensors to analyze:

• Driving habits (e.g., city vs. highway)
• Time elapsed since the last service
• Engine oil level and quality
• Distance driven
• Engine load and temperature

Based on this real-time data, the FSS calculates the optimal time for your next maintenance visit and alerts you via the main instrument cluster. This intelligent system ensures your vehicle gets serviced exactly when it needs it, preventing both premature and overdue maintenance.

Understanding Mercedes-Benz Service A

Think of Service A as the foundational check-up for your vehicle. It’s the first service your Mercedes will require, typically around one year of ownership or 20,000 kilometres, and it recurs every two years or 40,000 kilometres thereafter.

What’s Included in Service A?

While the exact list can vary slightly based on your model and year, a standard Mercedes Service A at a specialist shop like Boosted Auto Works includes:

• Synthetic Motor Oil Replacement: Draining the old oil and refilling with Mercedes-Benz approved synthetic oil to ensure optimal lubrication and engine protection. You can learn more about the benefits of synthetic oil from high-authority sources like Mobil 1.
• Oil Filter Replacement: Installing a new, genuine-quality oil filter to capture contaminants and keep your new oil clean.
• Fluid Level Checks & Corrections: Inspecting and topping up all key fluids, including coolant, brake fluid, power steering fluid, and windshield washer fluid.
• Tire Inflation Check & Correction: Ensuring all tires (including the spare) are inflated to the correct pressure for safety, fuel efficiency, and even tire wear.
• Brake Component Inspection: A visual inspection of your brake pads, discs, and lines to check for wear and potential issues.
• Maintenance Counter Reset: Resetting the FSS to begin the countdown to your next required service.

Understanding Mercedes-Benz Service B

Service B is the more extensive of the two maintenance packages. It typically becomes due around the two-year/40,000-kilometre mark and alternates with Service A. It includes every single item from Service A, plus several crucial additional tasks.

What’s Included in Service B?

In addition to all Service A items, Service B adds:

• Cabin Dust/Combination Filter Replacement: This filter cleans the air that enters the passenger compartment. Replacing it is essential for air quality and HVAC system performance.
• Brake Fluid Exchange: Brake fluid is hygroscopic, meaning it absorbs moisture over time. This moisture can lower the fluid’s boiling point and lead to corrosion in the brake lines. A full exchange is critical for braking safety.
• More Comprehensive Inspections: Service B often involves deeper checks of suspension components, steering systems, and the exhaust system for any signs of wear or damage.

What is the Mercedes Service B Cost in Markham? (And Service A)

This is one of the most common questions we hear from Mercedes owners in Markham, Scarborough, and the surrounding areas. The exact cost can vary, but here’s a general breakdown:

• Mercedes Service A Cost: As the more basic service, this is the less expensive of the two. The price primarily covers the cost of high-quality synthetic oil, a filter, and about one to two hours of a certified technician’s time.
• Mercedes Service B Cost: The cost for Service B is higher because it involves more parts (like the cabin air filter) and more labour (for the brake fluid exchange and deeper inspections). The Mercedes Service B cost reflects the comprehensive nature of this critical maintenance.

Important Note: The final price for either service can be affected by your specific Mercedes model (an AMG C63 will differ from a GLC 300), its age, and whether the inspection reveals any additional issues that need attention, such as worn brake pads or tires. We believe in transparency and will always provide a clear estimate before any additional work is performed. For a precise quote for your vehicle, we recommend booking a maintenance appointment.

Service A vs. Service B: A Clear Comparison

To put it simply:

• Timing: Service A is first, then Service B, then A, then B, and so on.
• Scope: Service B includes everything in Service A, plus a cabin filter change and a brake fluid exchange.
• Cost: Service B is more expensive due to the extra parts and labor.

Why You Can’t Ignore Your Service Reminders

Ignoring the FSS alerts is a recipe for expensive problems down the road. Sticking to the A/B schedule is the most effective way to:

• Prevent Major Breakdowns: Regular inspections catch small issues before they become catastrophic failures.
• Maintain Performance & Efficiency: Fresh oil, clean filters, and correct fluid levels allow your engine to run as efficiently as designed.
• Protect Resale Value: A complete and documented service history from a reputable shop is a major selling point.
• Ensure Safety: Regular brake and tire checks are non-negotiable for the safety of you and your passengers.
