When their vehicle needs to be serviced, owners of Mercedes flexible service systems are usually notified.

Mercedes B3 Service [What Is Included & Checklist, Cost]

It was the same message that puzzled me two years ago. The purpose of this article is to share my own experience with the Mercedes B3.

With my mechanical experience and as a proud Merc owner, I explain in detail what the B3 service is, how it is performed, and what the cost is.

What Is Mercedes B3 Service?

The Mercedes B3 service consists primarily of oil and filters.

Each year or after 60,000 miles, Mercedes-Benz performs a B3 service involving oil and filter replacement.

This maintenance service also contributes to road safety by inspecting the brakes and suspension and checking fluid levels.

If you fix the issues related to these components, your vehicle will perform better and last longer.

Mercedes B3 Service: What’s Included?

The following is a detailed description of Mercedes B3 services:

Spark Plug Service

The comfort and performance of Mercedes-Benz vehicles make them perfect for road trips.

Spark plug failure can occur when the vehicle is idled for a long period of time and driven at a low speed.

Spark plugs need to be changed if the engine has a rough idle, misfires, or surges. Keeping the fuel injectors and air filters clean can also prevent long-term spark plug stalling.

Air Filter Replacement

Dust accumulates in Mercedes-Benz air filters when driving on dusty roads. A clogged air filter will cause the engine’s oil to become dirty and will result in poor performance.

A B3 service on Mercedes is an excellent option in addition to inspecting and replacing the air filters. By removing dust from the engine, new filters will allow it to run at its best.

Inspection of brake components

Safety on the road is greatly enhanced by the brakes of a vehicle. The pedal may not transmit pressure to the wheels when there is a leak of brake fluid.

Depreciation of the discs can also lead to brake failure, making it more difficult to stop the vehicle. By performing routine maintenance, such situations can be avoided.

Brake pads, shoes, and brake fluid are all checked during an inspection of Mercedes B3 brakes. Through this process, it is possible to detect damage and malfunctions before they cause severe problems.

Replacement of synthetic motor oil

For maximum engine performance, Mercedes-Benz models should be serviced once a year or every 10,000 miles with synthetic oil.

Optimal heat distribution will prevent overheating and surges with the new oil. In addition to engine oil replacement, Mercedes-Benz B3 services include transmission fluid replacement.

I recommend obtaining synthetic oil from an authorized Mercedes dealer who has a good reputation. Regular oil can be adversely affected by weather conditions, causing engine failure.

Check and correction of all other fluids

Fluid is required for the operation of several Mercedes-Benz components. These fluids usually drain out as a result of leaks, which interferes with their performance.

Mercedes’ B3 service includes checking all fluid levels and correcting if needed. You need to check and correct fluid levels based on your car’s model, year, and interval.

My recommendation is to read your car’s manual to find out what fluids need to be inspected and replaced regularly.

How Much Does Mercedes B3 Service Cost?

A Mercedes-Benz B3 service generally costs between $200 and $450. Among the services included in the B3 service are an oil change, a brake inspection, and a suspension inspection.

Fluid levels can also be checked and corrected if necessary. It is necessary to perform this B service on your Mercedes if you have not serviced it for one year.

The cost of maintenance services is higher than Mercedes A services because maintenance services require component replacement. There are many factors that influence Mercedes-Benz B3 service costs, including model, year, and component replacement.

Mercedes-Benz models are more expensive to maintain and service compared to older models. Replacement of worn-out brakes and suspension components is extremely expensive since they are available in sets.

You should seek out an independent mechanic rather than going to a dealer with a warranty and service plan in order to get a fair price.

Furthermore, regular oil does not dissipate heat, so it shouldn’t be used in your engine. The best engine performance comes from synthetic oil, which is more expensive than regular oil.

If you want to avoid overpaying for a technician, you should research the ones who are available in your area. Ensure your mechanic has experience working on all Mercedes-Benz models when choosing a mechanic for the B3 service.

Why Is a B3 Service So Expensive?

You might wonder why Mercedes-Benz’s B3 service is so expensive if you own one. Can you tell me why the price is so high?

There is a greater degree of comprehensiveness in B-services (B1, B2, B3, etc.) than in A-services (A1, A2, A3, etc.). Consequently, last year you paid a lot less for A3.

There are complex systems and sophisticated technology in Mercedes-Benz vehicles, which require technicians to diagnose and repair. By leveraging their expertise, B3 services will keep your vehicle in top condition.

The exclusivity of Mercedes-Benz also influences its service costs. As a luxury brand, Mercedes-Benz has a reputation for innovation, comfort, and performance.

They also offer high levels of service and maintenance (like Audi, BMW, and others). This leads to the high cost of maintenance as well.

As part of Mercedes-Benz’s total cost of ownership, a Mercedes-Benz B3 service is part of the maintenance costs.

Find a trusted mechanic who knows Mercedes in your area if you need a mechanic who knows Mercedes. The service you receive will often be more personalized as well as saving you money.

How Often Should a B3 Service Be Performed?

After 60,000 miles (or the sixth year of ownership), Mercedes B3 services are typically required. Based on the Flexible Service System, the EXACT time will be determined. It will take approximately a year (or 10,000 miles) for the A3 service to be completed.

Your vehicle will display a message stating that the B3 service is due, that the B3 service is overdue, that the B3 service is overdue by X days, or that the B3 service was performed. You should not worry if you don’t remember the precise date.

Benefits Of Mercedes Service B3 Maintenance

Enhances acceleration and driving

During Service B3, spark plugs and air filters are replaced to enhance your vehicle’s performance. Your car’s engine will function more efficiently with new and clean spark plugs and air filters, which will improve acceleration and overall driving satisfaction.

Improved Fuel Efficiency

In order to maintain a properly maintained engine, synthetic oil should be changed regularly and fluid levels should be checked. With clean oil, fuel consumption and costs can be reduced, since friction is reduced and the engine runs more smoothly.

Maintaining Resale Value

Service B3 can detect potential problems before they become serious by performing a detailed check and replacement. By practicing proactive maintenance on your vehicle, your resale value can be preserved over time.

Enhanced Safety Features

This service includes an inspection of the brake components of your vehicle, which enhances its safety significantly. Identification of potential brake system issues early on will prevent your vehicle’s stopping ability from being compromised.

Prevents costly repairs

It is important to maintain your equipment regularly through Service B3 in order to avoid future costly repairs. Addressing minor problems during service can prevent severe damage from occurring.

How to Reset Service B3 on a Mercedes in 4 Steps?

Step 1: Start the ignition process

Once you turn on the ignition, you will see the mileage displayed on the dashboard. In order to start the engine, the key should be turned to the first position. The steering wheel is where the navigation buttons are located.

Step 2: Navigate to the ‘Trip’ menu

Press the left navigation button to reveal the “Trip” menu. While holding down the call button, hold down the “OK” button for about five seconds.

By clicking this button, you will be taken to the shop menu. You can find “Trip” by scrolling down.

Step 3: Locate ‘Assyst Plus’ and select it

By repeatedly pressing the down navigation button, you will find the “Assyst Plus” option. You can confirm by clicking “OK”.

The next step is to select “Full Service” and “Service Data”. By clicking the down arrow again, you will be able to select “Full Service”.

When you reach “Conf.”, scroll down with the down button. Click on “Full Serv.” when you reach it. Choose your option. Following this, you will be asked, “Service carried out? ”.

Click the down arrow and select “Yes” to confirm your choice.

Step 4: Finalize the process

A message stating “Cannot be done.” will appear. Select “Confirm” by using the down button. Once you’ve understood, click “OK”.

The service light will be reset by confirming, and this cannot be reversed. At the end of the process, a message will ask, “Full Service Carried Out? ”.

Click “OK” to confirm your approval. In order for the system to continue, each step must be confirmed.

The reset may not work on all Mercedes models, but it will work on most Mercedes models.

How Long Does a B3 Service Take?

A Mercedes B3 service typically takes 2-3 labor hours, but it varies greatly based on its location, season, and maintenance needs.

With trained mechanics and streamlined processes, independent specialists cannot compete with dealer shops. Independents, however, typically charge lower wages. Spring and fall are the busiest seasons for shops, so they may experience longer wait times during these times.

The level of staffing in a shop also affects turnaround time. In addition to the B3 checklist, the maintenance process will take longer if more requirements are added. While the B3 service alone may take 2-3 hours, shop delays, seasonal demands, and any additional maintenance may increase the total time to over 3 hours.

Can I Do a B3 Service Myself?

Performing Mercedes B3 services on your own is possible. Before embarking on this project, it is important to consider several factors.

First, make sure you have the right tools, knowledge, and skills. Spark plug replacements, brake fluid changes require more expertise and tools (e.g., brake fluid changes) compared to oil changes, air filter replacements.

An effective service on your car requires knowledge of its components and functions. Information about these aspects can be found in several sources, including specific model-specific service manuals, forum posts by users, YouTube videos, and even your vehicle’s owner’s manual.

Second, do not do a B3 service yourself without consulting a professional. Performing the required tasks without being careful or experienced can result in mistakes or even car damage.

It is also possible to void your warranty if you perform a B3 service yourself. Check your car’s warranty terms and conditions to understand the implications of performing the service yourself. Some warranties may be voided by non-authorized professionals.

B3 services can be performed by DIYers, but they must consider their skills, the tools they have available, the risks they may face, and any terms and conditions that may apply. In spite of the fact that you will save some money, you should keep in mind that Mercedes-Benz parts are not exactly cheap, so even if you save some money, you won’t be able to afford them.

Choosing the Right Service Center

Authorized Mercedes Service Centers

Your first step should be to locate certified Mercedes-Benz service centers. With this certification, Mercedes-Benz ensures that the service center has been specially trained to work on Mercedes vehicles, which ensures that it has the necessary technical know-how and tools. The fact that these centers provide high-quality services is likely due to the fact that they have up-to-date information and tools.

Customer Reviews and Testimonials

Performing research on a service center requires evaluating its reputation. It is possible for customers to share their experiences through digital platforms through reviews and ratings.

Customers are likely to be more satisfied with a service center if they receive comments that highlight professionalism, quality of work, and commitment.

Centers with a strong Mercedes track record

Experience is crucial when it comes to automobile service. Established service centers tend to accumulate extensive knowledge and expertise in order to serve vehicles of varying makes and models, allowing them to efficiently handle complex services, such as Service B3.

Get An AASE-Certified Mechanic To Work On Your Vehicle

Having passed rigorous tests and gained professional experience in a variety of areas related to vehicle maintenance and repair, they are qualified to perform vehicle maintenance and repairs.

Use of Genuine Parts

Mercedes-Benz service centers are the only ones qualified to replace parts during Service B3. To maintain your vehicle’s performance and resale value, you should use genuine parts. Parts that are authentic are guaranteed to fit and function perfectly.

Communication and transparency

Service centers that communicate well with their customers are the ones that succeed. You should be able to get clear explanations of the Service B3 procedures from them if you have any questions about them.

Tips for Maintaining Your Mercedes Between B3 Services
