What is Service B5?

This is maintenance carried out in Mercedes Benz, which is performed approximately every 20,000 miles or 2 years, whichever comes first.

Just like other ranges of B servicing such as the Mercedes service B1 down to Mercedes service B9, the B5 service is intended to keep your vehicle in top condition and keep it running smoothly by focusing on a specific checklist of tasks like we’ll see in the next section.

What Does Service B5 Include?

1. Motor Oil Replacement

This service includes changing the oil in your car, which helps to lessen and remove extra dirt that can build up in your engine over time. In essence, oil changes help to keep your engine clean. The top-quality synthetic oil will support the continued efficient operation of your Mercedes for many miles to come.

2. Cabin Filter Replacement

The cabin dust/combination filter is also changed as part of an oil change procedure to keep your car safe from dangerous impurities dust and other particles. Because if not replaced the specks of dirt can seriously affect your vehicle’s air conditioning system over time. 

3. Tire Pressure Checks

The right pressure levels are checked in the tires to prevent issues like premature tire wear or bad handling from occurring. If there is not much pressure, enough air would be added to it for better performance.

4. Oil Filter Replacement

One of your car’s most crucial maintenance tasks is changing the oil filter in the engine. This component filters the engine oil that lubricates your engine’s internal parts of combustion contaminants, dirt, and carbon deposit. But over time, it gets more clogged as a result of debris making it hard for clean oil to pass through.

This is why a new oil filter is installed in your Mercedes Benz during service b5. This new filter aids in preventing contaminants from entering the engine and harming it or degrading its performance. 

5. Checks on Fluid Levels

The proper amounts of oil, coolant, brake fluid, and power steering fluid are all examined.

6. Brake Fluid Change

We recommend replacing your brake fluid every two years as part of a thorough examination. But as a Mercedes driver, you need to keep up with the instructions of the system on when to change the fluid. This is to ensure that your braking system is operating as it should at all times.

7. Tire Rotation

Vehicles with two rear tyres are being rotated to ensure that all tires wear equally and last longer. the mechanic can take each tire from your car and relocate it to a new position during rotation.

This will be achieved if the tires are rotated in a forward cross pattern. This implies that the left front moves to the left rear and the right front goes to the right rear. The right rear moves to the left front, and the left rear moves to the right front. 


Does Service B5 Require Much Time?

It depends greatly on the model. But typically, service periods are between 2 and 6 hours. As you might expect, servicing a car requires more time the more complex it is. B5 work typically takes place on the same day.

What is the Cost for Mercedes Service B5?

Compared to the price of a “Service A5”, the expense of a Mercedes “Service B5” is variable. Depending on your car’s model and year, as well as the need for replacement components, you can anticipate spending anywhere from $400 to more than $700. 

This is because this service is more extensive than “Service A”. Due to the mileage and wear and tear on the car, it includes a variety of upkeep inspections and replacements. Therefore, for your car to last long, you must get all the treatments.
