The Mercedes Benz is a marvel of a machine. Not only does it feel like butter on the road, but it’s also one of the most reliable cars out there. However, routine maintenance is necessary to keep your Mercedes running like a well-oiled machine, like any other car.

Like most Mercedes Benz owners, you’re probably already familiar with Mercedes Service A. This is the first routine maintenance service performed every 10,000 miles or 12 months, whichever comes first. Service A includes an oil and filter change, as well as a tire rotation. But what about Service B?

There has been a lot of debate in Mercedes owners’ circles as to whether Service B is really necessary. While the German automaker certainly recommends it, most owners consider it a waste of time and money. The Mercedes Service B is crucial and will save you a lot of money in the long run, even though it may cost you a bit of cash.

Today, we take a deep dive into Mercedes Service B and let you in on everything you should know about it.

What Is Mercedes Service B?

Mercedes Service B is the second routine maintenance service that is performed on Mercedes Benz cars. Service B includes all of the Service A items, plus a few additional checks and services. The main difference between Service A and Service B is that Service B also includes a cabin air filter replacement and a brake fluid flush.

While these two additional services may not seem like much, they can make a world of difference in the long run. For instance, replacing your cabin air filter ensures that the air you’re breathing inside your Mercedes is clean and free of pollutants. And brake fluid flushes help to prevent your brakes from becoming corroded and damaged.

What Does Mercedes Service B Entail?

Mercedes Service B is an intricate service that includes a number of different checks and replacements. Here’s a quick overview of everything that Service B entails:

1. Oil and filter change

This is where Service B starts off. Service B includes an oil and filter change, just like Service A. The only difference is that Service B uses a higher quality of oil than Service A.

2. Tire rotation

A tire rotation is where they literally rotate your tires from one position to another. This helps to ensure even tire wear, which in turn extends the lifespan of your tires.

3. Brake Fluid Flush

A brake fluid flush is where they completely replace the brake fluid in your Mercedes. This is important because brake fluid can become contaminated over time and cause damage to your brakes.

4. Brake Component Inspection

In addition to flushing your brake fluid, Service B also includes a thorough inspection of your brake pads, discs, and calipers. This helps to ensure that your brakes are in good condition and won’t fail when you need them the most.

5. Cabin Air Filter Replacement

As mentioned earlier, Service B also includes a cabin air filter replacement. This helps to ensure that the air you’re breathing inside your Mercedes is clean and free of pollutants. It also ensures the longevity of your car’s HVAC system.

6. Replacement of Cabin Dust/Combination Filter

In addition to the cabin air filter replacement, Service B also includes the replacement of your cabin dust/combination filter. This helps to trap even more pollutants and dirt before they have a chance to enter your car’s cabin.

7. Tire Inflation Check and Corrective Action

Service B also includes a tire inflation check. This is where they check the pressure of your tires and inflate them to the correct level if needed.

What’s the Difference Between Service A and Service B?

The main difference between Service A and Service B is the time interval required for each. Service A is needed after every 10,000 miles, which translates to about one year. Service B, on the other hand, is required after every 20,000 miles, which roughly equals two years.

Aside from the time interval, Service B also includes a few additional services that Service A does not. They include a cabin air filter replacement, a brake fluid flush, and a brake component inspection.

Expect to pay around $600 for B-Class models and about $950 and above for diesel models. The cost of service B also depends on the location. Service B costs more in Europe than it does in the United States.
