As an ASE-certified master technician with over 15 years of experience, I understand the engineering and value behind Mercedes-Benz maintenance schedules.
The B2 service optimizes your vehicle’s performance and longevity by addressing critical components like oil changes, filter replacements (oil filter, Air filter, and Pollen), and more.
This guide will explain everything you need to know about the “Service B2” on your Merc. Let’s get into it!
Mercedes B2 Service Explained
The B2 service is the second major service interval for Mercedes-Benz vehicles equipped with the Flexible Service System (FSS). Typically performed around 40,000 miles or in the 3-4th year of operation (assuming 13500 miles/year).
The FSS monitors driving habits and usage to determine optimal service intervals. When due, the vehicle displays reminders for “Service B2.”
This interval includes standard items like an oil and filter change, brake inspections, and tire rotation. Additional items like cabin air filter replacement or brake fluid exchange may be required based on age and driving conditions.
What the Merceds Service B2 Includes
Now, let’s look at what’s included in this service.
Synthetic Motor Oil Change:
Synthetic oil is preferred for its long-lasting properties and superior engine protection. During the B2 service, the old oil is replaced with premium synthetic oil that meets or exceeds Mercedes-Benz specifications.
Oil Filter Replacement:
A fresh oil filter is integral to keeping the new oil clean. Only OEM (Original Equipment Manufacturer) filters are used to ensure the highest level of purity and protection for the engine.
Cabin Air Filter Replacement:
Breathing clean air inside your Mercedes is as important as the air the engine inhales. The cabin air filter is replaced to ensure that the interior air quality is free from pollutants, and dust.
Inspecting the Brake Components
Then, the mechanic will inspect the brake components. He visually checks the brake pads, rotors, calipers and hoses for any signs of wear, damage, or leaks.
Using a gauge, he measures the thickness of the brake pads to see if they need to be replaced soon.
Checking the Tire Pressures
Next, the technician checks the tire pressures. He uses a tire pressure gauge to check the air pressure in each tire and inflates them as needed to the vehicle manufacturer’s recommended specification.
Topping Up Fluid Levels
The technician then checks all fluid levels, including coolant, brake fluid, and washer fluid. Using the appropriate fluid, he tops up any low fluid levels to ensure they are at the proper level.
Brake Fluid Replacement:
Vital for braking, replacing the brake fluid prevents potential brake system malfunctions.
The service involves draining the old fluid, checking the system for leaks, and refilling with high-grade, manufacturer-recommended brake fluid.
Sunroof Guide Rails Cleaning:
The smooth operation of your sunroof hinges on the cleanliness and lubrication of the guide rails. Technicians meticulously clear out any debris and apply a specialized lubricant to ensure quiet and effortless sunroof movement.
Resetting the Service Reminder
Finally, the technician resets the service reminder system. Using a diagnostic scan tool, he connects to the vehicle’s computer and resets the maintenance interval display.
This notifies the vehicle computer that the scheduled B2 service has been completed.
