Service B3 Mercedes Code: Checklist & Maintenance Cost

Mercedes B3 is a maintenance code that specifically focuses on some services. Routine Maintenance services play a vital role in maintaining the longevity and performance of your Mercedes-Benz. 

However, some Mercedes-Benz owners and drivers need help getting accurate and relevant information about the B3 Service code on their vehicle’s displays.

This maintenance Minder emphasizes to the owner that a service is due and needs to be recovered. One and a half years ago, I too needed clarification on various messages.

That’s why this particular article is about Service B3 Mercedes. I am expressing my observation and personal journey with that code. You’ll gain detailed insight into its meaning, cost, and other factors.

What Is Service b3 mercedes?

In Mercedes, the engine oil and filter maintenance on their due is known as B3 service. In that service, some of the essential components of the vehicles required maintenance soon. 

When Should a B3 Service Maintenance Be Done?

Normally, this service should be done for your Mercedes after reaching its sixth year or after 60,000 miles. It typically will be 10,000 miles or one year after completion of the A3 service.

The same criteria apply to Benz models but can change slightly in other models, such as the C250, E350, ML350, C300, or GLA. Some other sub-services, like fluid level look-overs and brake inspections, are involved.

After service, your vehicle feels better performance on the roads, and ignoring that maintenance can put risks like low engine working and expensive costs on repair.

However, this is important to service B3 on its due. It can extend car safety, improve quality and capability, and save you from heavy costs.

What items are included in Service B3 Mercedes?

Here are the detailed themes that are included in B3 Service. These items are serviced on time to maintain the car’s overall health. 

Service Of Spark Plug

A trip can be more exciting and adventurous with the comfort of a Mercedes-Benz. However, driving vehicles at a very low speed or idling can cause the spark plug to fail. 

In that service, the mechanic inspects your car’s spark plugs to check performance and replace them if needed. He also replaced dirty air filters (required) and replaced injectors from harming the vehicle in the long run.

In B3 maintenance, spark plug inspection is one of the most crucial things. So, whenever your car’s engine experiences a rough idle or misfire, you should understand that spark plugs must be replaced. 

Replacement of Air Filter

Air filters help improve engine performance, airflow, and fuel consumption. In Mercedes-Benz, clogged air filters lower the engine’s power and efficiency. 

In the Service B3 Mercedes, the mechanic inspects the air filters and swaps the dirty ones with new ones. The newly installed filter New filters will stop the dust and allow the engine to run at its peak efficiency.

Inspection Of Brake Components

The safety of the road depends on brake components. The leakage of brake fluid will obstruct the pressure transmission of your Mercedes.

A detailed inspection checks the fluid, Padals and Pads, brake lines, and shoes. This extensive check allows any malfunctions before they can lead to more serious damages.

Due to the disc’s depreciation, the Mercedes brakes will also fail. So, getting routine maintenance is essential to avoid such bad circumstances.

 Replacement Of Synthetic Motor Oil

Synthetic motor oil replacement is important in Mercedes Service Code B3. Each Mercedes-Benz model requires oil replacement every 10,000 miles (once a year) for optimal engine execution. 

The old oil will be removed, and the new oil in that maintenance will be. That new oil prevents the car’s engine from overheating and ensures heat distribution.

The best practice is to try to get synthetic oil instead of regular oil because regular oil can’t support extreme weather and might impact the engine. I suggest you get this from an authorized and experienced Mercedes dealer. 

All Other Fluids Check and Correction

In Mercedes Benz cars, several parts require various fluids to work efficiently. Leakages of these fluids stop the operation of the components and cause issues.

Therefore, in B3 service, fluid checks and corrections are important if required. These checks and corrections can depend on the car’s model, year, and interval. I also suggest reading the car manual.
