As an experienced Mercedes services technician, I’ll assist you in understanding what actual Mercedes Service B means, what checklist mechanical tasks you’ll perform, how much it costs, why it’s important, and exploring the difference between Service A and Service B.
What is Mercedes-Benz Service B?
Service B Mercedesis a regular maintenance service that is more comprehensive than service A, typically performed two years after the initial purchase date or around the 20,000-mile mark.
It’s a generally scheduled service period, but it can vary with your Mercedes model, how often you drive, driving, conditions, and manufacturing year. Mercedes B service includes additional components inspections, systems addressing, and replacement or changing of additional fluids compared to service A.
Mercedes-Benz Service B Checklist
Here’s the breakdown of service b detailed checklist, which includes fluids changes, various Mercedes parts and system inspections, diagnosis with the tool, replacements of different components, and systems reset, which helps maintain vehicle performance and improve efficiency for longevity and smooth experience.
Synthetic motor oil replacement
Changing the old engine oil with the manufacturer’s suggested synthetic oil is the first and most crucial aspect of service B Mercedes. Over time, engine oil becomes contaminated & viscous, which needs to be replaced to keep the engine lubricated and prevent the interior moving components from wear & tear or friction that can damage them.
Oil filter replacement

Changing the oil filter along with the synthetic oil is mandatory as it performs a crucial function in cleaning the engine oil from contaminants that can impact engine efficiency and reduce performance. Over time, the tiny hard particles and contaminants accumulate in the motor oil, which, if left unfiltered, can affect the engine’s ability to perform.
Brake fluid changing
During service b, brake fluid is exchanged to maintain the amplifying braking force, which keeps the brakes efficient and responsive. Over time, you might feel spongy while pressing the brakes, a sign of changing the fluid.
Tire rotation and pressure check
The next part of service B Mercedes is to rotate the tires to look for any signs of wear that might be dangerous in the future if left unchecked. If any tire is worn, it will be replaced, and the mechanic will check tire pressure for optimal performance and longevity without any occasional issues.
Cabin air filter replacement
The old cabin air filter is replaced to ensure clean air enters the engine, as clogged or damaged air filters can cause a lean air-fuel mixture, leading to other critical damage. That’s why changing the air filter is necessary during Mercedes-Benz B service.
Brake components inspection
Inspecting the braking system components, including pads, calipers, and rotors, is crucial for safety and vehicle performance, as small wear & tear on these braking system parts can become a larger and costlier problem if not inspected properly.
Battery test and inspection

A battery test and inspection of both terminals helps to identify their condition and whether they need replacement or delivering an accurate quantity of volts needed for vehicle operations. If the battery is found to be weak, old, or not supplying enough volts, the technician would recommend replacing the faulty one and installing a new one.
Suspension & steering components checking
For a smooth and safe vehicle experience, the mechanic checks the suspension and steering components and will fix the occurring issues to keep the upcoming journeys safe from sudden or critical damages.
Reset maintenance counter
At the end of the Mercedes-Benz Service B, when all the mechanical tasks are completed, the mechanically resets the maintenance counter, which helps to record when you need to perform the next service, such as A1, B1, A2, B2, A3, B3, A4, B4, A5, B5, A6, B6 etc.
