Does your Mercedes-Benz dashboard display the Mercedes B1 service code? Are you looking for information regarding this message, the cost to fix it, and what it includes?
In order to maintain an extended lifespan and stable performance, you must keep up with a Mercedes’ service schedule. It is one of the most important maintenance milestones for Mercedes-Benz vehicles to receive the B1 service.
This article explains everything you need to know about the B1 service. A Mercedes-Benz dealer recommends B1 service every year or 20,000 miles, similar to the other error codes. Unlike a typical checkup, it contains a comprehensive list of different maintenance tasks designed to maintain the durability and performance of your vehicle.
What Is The Mercedes B1 Service?

Similarly to other luxury and premium car manufacturers, Mercedes service intervals are coded. Among the benefits of the B1 service are oil changes, brake inspections, and cabin and air filter replacements. It’s important, however, to understand these codes if you want to prolong the life of your vehicle.
What Includes In The B1 Service?

In order to keep your vehicle healthy, it is important to maintain it regularly. Having worked on Mercedes-Benz vehicles for more than 10 years, I strongly recommend that you get the b1 service as soon as possible. As a result, the following sub-services are part of B1 maintenance:
- Engine oil and filter replacement
- Fluid level checks
- Fluid change
- Brake components inspection
- Cabin and engine air filter replacement
- Tire rotation and pressure checks
- Electrical system inspection
Engine Oil And Filter Replacement
Having new, clean engine oil is like having blood in your car; a well-functioning engine depends on it. Since it is of such importance, Mercedes replaces its old oil with a high-quality synthetic engine oil during its B1 service.
In addition to changing the oil, replacing the oil filter is also essential. It is essential that your oil filters ensure the safety and cleanliness of your engine by preventing debris and contaminants from entering.
For the engine to stay healthy and perform at its best, these two steps must be performed at the right time. When that B1 service is performed, synthetic oil is used because it provides long-lasting lubrication and prevents debris and contaminants from damaging the engine.
Fluid Level Checks & Change
It is crucial to check your vehicle’s fluid levels regularly to ensure it operates smoothly and has a long lifespan. It is essential that you inspect the fluid levels in your Mercedes car in order to ensure that it runs efficiently and safely.
The fluids of the Mercedes-Benz were thoroughly checked and refilled according to their markers as part of the Service B1 Mercedes-Benz.
In order for brakes to respond properly, they need to be maintained. The service prevents expensive repairs and ensures that the vehicle is safe from mechanical problems while on the road.
Brake Components Inspection
The brake system is one of the most essential safety elements of any vehicle. It is essential that you inspect and maintain the brakes on your vehicle regularly in order to ensure its safety and reliability.
The technician will then inspect the hole brake system after checking the fluid level. Various brake components, such as brake pads, shoes, rotors, drums, and calipers, are inspected to ensure the brakes work well.
Cabin And Engine Air Filters Change
It is imperative that you maintain a clean air filter in your Mercedes in order to ensure optimal performance and comfort. The cabin air filter and engine air filter both play an important role in keeping your engine running smoothly and absorbing clean air.
During the course of the air conditioning system (HVAC) and ventilation, air enters your vehicle’s engine through the cabin air filter. As a result, passengers breathe cleaner air because pollen, dust, and other particles are trapped in the filter.
In order for the vehicle’s engine to run smoothly and last as long as possible, it needs an engine air filter to prevent dirt, debris, and contaminants from absorbing into the engine. The operating performance and fuel economy of the engine are also improved by clean air filters.
Tire Rotation And Pressure Checks
Mercedes-Benz recommends rotating tires and checking tire pressure as part of Service B1 to enhance the vehicle’s safety, capability, and tire longevity.
The process of rotating tires ensures even tire wear by moving them from one side of the vehicle to the other. In addition to improving overall tire performance, this procedure helps extend their lifespan.
It is critical to check the tire pressure of the vehicle to ensure its safety and fuel efficiency. An underinflated or overinflated tire can cause poor handling and increased tire wear, even resulting in a blowout. Both tasks require regular maintenance, so it is recommended to perform them regularly.
Electrical System
Various functions are performed by the electrical system in your Mercedes-Benz, including starting the engine, lighting, and regulating various functions. To keep your Mercedes running smoothly, it is essential that the electrical system is well maintained.
An expert performing the B1 Service performs a detailed inspection of the electrical system to identify faulty components and replace them.
Mercedes B1 Service Cost

Depending on your GEO location, vehicle needs, and labor rate, the cost of B1 service maintenance can vary significantly. Nevertheless, B1 services are estimated to cost between $380 and $700 on average. If you would like to know the exact price, you can contact your nearest repair shop.
