Mercedes B0 Service (Cost, Checklist, What’s Included)

Owning a Mercedes means luxury and precision maintenance at the right time. Mercedes B0 service is a routine maintenance interval that serves as a regular check-up to keep your vehicle in optimal condition.

As a mechanic, I will explain everything you need to know about Mercedes-Benz B0 service—including its cost, checklist, what’s included, and answers to common owner questions.

What Is Mercedes B0 Service?

Mercedes B0 service is a part of the Flexible Service System (FSS) for schedule-based maintenance by Mercedes-Benz. 

The “B” in B0 is for a more comprehensive service as opposed to the “A” service, while the “0” indicates a certain subgroup within available services. 

Typically required every 20,000 miles or 2 years, the B0 service makes sure that critical components of your Mercedes-Benz have been inspected, maintained, and serviced to factory standards.

What’s Included in Mercedes B0 Service?

The B0 service involves both inspections and replacements. Below is a complete checklist:

Mercedes B0 Service Checklist:

Every service is performed at an authorized facility by a certified Mercedes-Benz technician using OEM parts and fluids approved by Mercedes, ensuring your warranty remains intact and prolonging your vehicle’s life.

Some of them are below:

Oil Change

The oil change is the core component of the B0 service. During this process, the technician extracts the old oil—which degrades and becomes contaminated over time—rendering it less effective in lubricating and cooling the engine.

New oil is important since it allows the engine to operate smoothly by cutting down on friction in addition to cooling it. During this process, the filter is also changed to keep the fresh oil clean. Routine oil changes extend the life of your engine and allow it to perform optimally. 

Oil Filter Replacement

The oil filter plays a crucial role in maintaining your engine’s condition by cleaning impurities and dirt from the oil before they can cause damage.

If the filter becomes clogged or dirty, it reduces the oil flow to the engine, thereby increasing wear and tear. This is why it is important to replace the oil filter during the B0 service: to keep the engine protected and running smoothly.

Air Filter Change

The air filter allows only clean air into the engine, thereby ensuring smooth operation. If it is clogged, the engine has to work harder, which can reduce power and increase fuel consumption.

Under the B0 service program, your air filter is inspected and replaced if necessary to ensure optimal engine performance.

Pollen Filter Change

The pollen filter cleans the air that enters the vehicle’s interior through the heating or air conditioning system.

A dirty pollen filter can allow dirt and allergens to compromise the interior air quality. During B0 service, the pollen filter is inspected and replaced if required to keep the cabin air fresh and clean.

Brake Fluid Flush

According to Mercedes-Benz’s recommendation, the brake fluid should be changed every two years, although this may vary based on the car model, driving conditions, and driver habits. Over time, brake fluid absorbs moisture, which can lead to rust and reduced braking efficiency. The B0 service includes a brake fluid flush every 12 months, which is beneficial for the proper functioning of the brakes.

Brake Pad Inspection

Brakes are one of the most critical safety components of an automobile. During a B0 service, technicians inspect the entire brake system as part of a comprehensive check. Brake pads wear over time; worn-out pads may cause noise, vibrations, or trigger dashboard warnings. For safety, it’s advisable to inspect brake pads every six months and replace them as needed. 

Tire Rotation and Replacement

Regular tire rotation promotes even wear, increasing tire lifespan and reducing replacement costs. Mercedes-Benz recommends rotating tires every 5,000 miles, although the frequency may vary depending on the car model, driving habits, and tire type. If your dashboard indicator shows that a B0 service is due, it is best to consult a qualified Mercedes-Benz technician to determine your car’s specific needs.

Mercedes B0 Service Cost (Full Breakdown)

The average cost for Mercedes B0 service ranges between $400 and $600, depending on several factors:

Note: Prices will change according to locality, dealership, and vehicle model (e.g., C-Class, E-Class, etc.).

How Often Do You Need B0 Service?

Mercedes recommends performing the B0 service every 20,000 miles or 2 years, whichever comes first. Conditions of driving and model year could, therefore, alter this.

For example, if driving conditions consist of a lot of stop-and-go and harsh environments, then B0 might be done even sooner. When it’s really time, you’ll receive a notification that will pop up on your dashboard courtesy of the Mercedes-Benz Service Minder. 

B0 Service vs A0 Service: What’s the Difference?

The B0 service is more comprehensive and includes additional checks to keep your car in top shape.

Can You Do the B0 Service Yourself?

Certain tasks, such as changing oil and filters, can be performed by the owner; however, the rest of the B0 service requires specialized diagnostic tools, software for system resets, and qualified technicians—resources that most owners do not have access to.

To keep your warranty intact as well as the resale value of your car, it is best to have the B0 service done by an authorized Mercedes-Benz service.

Is B0 Service Covered Under Warranty or Prepaid Plans?

Usually included with the Mercedes-Benz Prepaid Maintenance Plan, the B0 service could also be covered by extended warranties or CPO (Certified Pre-Owned) packages, depending on the terms.

For confirmation, you should always consult your service booklet or My Mercedes me account.

Why B0 Service Matters for Your Mercedes

Skipping or delaying a B0 service can lead to:

• Premature engine wear
• Brake system issues
• Reduced fuel efficiency
• Voided warranty
• Lower resale value
