ALEX HARPER

You feel love when you drive your Mercedes and it exudes elegance. The dash notification for “Mercedes B6 Service” means you should be concerned when you see it. 

In order to understand this service, one must first ask, “What does it mean?”. Is your Mercedes in need of any services? What is the cost of maintenance?

My goal is to break down all the services included in that code, where to get them and when to get them so that you can save some time and money.

Mercedes B6 Service

Exactly what is Mercedes B6 Service?

This Mercedes B6 service is intended to maintain optimal performance of your car and is performed about 10k miles after your A6 service. In Mercedes-Benz’s Flexible Service System (FSS), regular maintenance intervals are determined by mileage, time, and use.

The specific tasks included in a B6 service may vary depending on whether your car is gasoline-powered or diesel-powered. However, it includes all the standard tasks included in a “B” service plus four additional B6-specific tasks. Mercedes’ B6 service is the most involved out of all scheduled services.

What is the best time to service your B6 Mercedes?

In the sixth year of ownership, Mercedes models typically receive 120k miles. If the previous A6 service was completed on time, you’ll need to schedule the service after one year.

Do not worry if you’re not sure when your Mercedes-Benz needs maintenance. You’ll receive a message on the dashboard when it’s time for service, such as “B6 Service”, “Due B6 Service”, Overdue B6 in 3 days,” “Service B6 due soon”, or “Service Code B6”.

What Is Included In Maintenance B6 Service?

Service B6 is an important and prominent service in Mercedes-Benz’s maintenance schedule. This code includes the following service items:

Replace the air filter

In order for the engine to function properly, it needs clean, dust-free air. It is recommended that you replace your Mercedes-Benz’s air filter regularly to ensure that the engine receives clean, filterless air.

For that service, a new, clean air filter was replaced with the dirty/old one. In order to improve airflow, these steps are crucial.

Spark Plug Replacement

In order for an engine to begin and maintain combustion, Spark Plugs play a crucial role. Those plugs become less efficient with time due to wear and tear.

For a smooth ride and better fuel economy, it would be helpful if you had Service B6 Mercedes on its schedule or due time. By following these practices, you will prevent your car from idling and misfiring and will be able to gain insight into your journey.

Replace Brake Fluid

A vehicle’s braking system can be affected by moisture absorbed by the brake fluid. In Service B6, your Mercedes is checked to determine whether it is in brake command or not. Performing this service can maintain the brakes’ responsiveness and safety.

Degrease and clean the guide rails on the sunroof

It is important to maintain clean sunroof tracks in order to maintain smooth, quiet drives, but dirty sunroof tracks can lead to leaks and obstruct the experience.  

Maintaining the sunroof’s operational capability is an essential part of B6 Mercedes service. Guide rails will be cleaned and degreased by a technician assigned to the project. Maintaining your Mercedes-Benz’s luxury experience begins with regular cleaning of the sunroof.

Replace Synthetic Motor Oil

Synthetic engine oil needs to be changed at a slower pace than conventional oil at 10,000 miles. As a result of low lubricant effectiveness, friction is increased, and new synthetic oils with excellent lubricating power are good for engines. 

Oil Filter Replacement

Engine oil and filter changes can have a significant impact on the engine’s operating system. Oil stays free from dust and debris for much longer when the old filter is replaced with a new one that is fresh.

Check Fluid Levels

Ensure that fluid levels meet the criteria to maintain the longevity of your Mercedes Benz. Check the transmission fluid, brake fluid, coolant fluid, power steering fluid, and windshield washer fluid regularly. In these components, fluids play a crucial role.

Check the tire pressure

B6 service provides you with an opportunity to ensure that your car’s tires are correctly inflated. You can extend the tire’s lifespan by performing this task, but it can also increase risk and reduce your Mercedes’ handling capabilities. 

Check the brake components

There will be an inspection of the brake pads, calipers, rotors, and overall braking chain to see if there have been any issues or improvements in the maintenance. Having a good set of brakes is crucial to the safety of your vehicle on the road.
