To ensure a long-lasting and safe performance on different roads, Mercedes-Benz vehicles require routine maintenance.
B3 service messages on Mercedes-Benz vehicles are difficult to obtain accurate and relevant information about.
A reminder is usually sent to the owner when the Mercedes flexible service system needs to be serviced.
This very message puzzled me two years ago as well. So, I’ve written this article to share my own experience with Mercedes B3.
Based on my experience as a mechanic and a proud Merc owner, I provide a detailed explanation of what the B3 service entails, how it is performed, and how much it costs.
What Is Mercedes B3 Service?
Oil and filters are the main components of the Mercedes B3 service.
During Mercedes-Benz’s B3 service, an oil and filter change is performed every 60,000 miles or after one year.
Since the maintenance service includes brake and suspension inspections and fluid checks, it also contributes to road safety.
It will improve the performance and prolong the lifespan of your vehicle if you correct the issues related to these components.

Mercedes B3 Service: What’s Included?
Detailed information about B3 services can be found below:
Spark Plug Service
Mercedes-Benz vehicles are comfortable and perform well on different terrains, making them ideal for road trips.
Idling the vehicle for long periods of time and driving at low speed can result in spark plug failure.
A rough idle, misfires, or surges are signs that the spark plugs need to be changed. Additionally, keep the air filters and fuel injectors clean to avoid long-term stalling of the spark plugs.
Air Filter Replacement
As a result of driving on dusty roads, Mercedes-Benz air filters accumulate dust. The engine’s oil will become dirty and will perform poorly if the air filters are clogged with dust.
In addition to inspecting all the air filters and replacing them if necessary, a B3 service on Mercedes is an excellent option. Dust will be trapped by new filters, allowing the engine to run at its best.
Inspection of brake components
The brakes are one of the most important components of a vehicle that contributes to safety on the road. It is possible for brake fluid leaks to prevent pressure from being transmitted from the pedal to the wheels.
Disc depreciation will also cause brake failure, making it harder to stop the vehicle. It is possible to avoid such situations by performing routine maintenance.
An inspection of Mercedes B3 brakes involves checking the pedal, brake fluid, brake lines, shoes, and pads. Damages and malfunctions can be identified before they cause severe problems through this process.
Replacement of synthetic motor oil
It is recommended that Mercedes-Benz models be serviced with synthetic oil once a year or every 10,000 miles for maximum engine performance.
With the new oil, the engine will be protected from overheating and surging by optimal heat distribution. Mercedes-Benz B3 services include engine oil replacement.
My recommendation is to obtain synthetic oil from an authorized Mercedes dealer who is reputable and reputable. Weather conditions can adversely affect the performance of regular oil, which can result in engine failure.
Check and correction of all other fluids
Several components on Mercedes-Benz models require fluid for operation. Leaks usually cause these fluids to drain out, which interferes with their operation.
As part of Mercedes’ B3 service, all fluids need to be checked and corrected, if necessary. Depending on the car model, year, and interval, fluid levels need to be checked and corrected.
To find out which fluids need to be inspected and replaced frequently, I recommend reading your car manual.
How Much Does Mercedes B3 Service Cost?
In general, Mercedes-Benz B3 services cost between $200 and $450. An oil change, brake inspection, and suspension inspection are included in the B3 service.
Other minor services include checking and correcting fluid levels if necessary. If your Mercedes has not been serviced for one year after its last service, then this B service is required.
Due to the fact that maintenance services require component replacement, they are more expensive than Mercedes A services. Model, year, and component replacement all influence Mercedes-Benz B3 service costs.
The maintenance and service costs for modern Mercedes-Benz models are higher than those of older models. Since brakes and suspension are available in sets, replacing worn-out components is extremely expensive.
To achieve a fair price charge, I recommend seeking an independent mechanic instead of going to an authorized dealer (unless you have a warranty and service plan).
In addition, regular oil should not be used in your engine because it does not dissipate heat. Although synthetic oil is more expensive than regular oil, I recommend it for optimal engine performance.
It is important to research the available technicians within your vicinity before you pay too much. When choosing a mechanic for the B3 service, make sure they have experience working on all Mercedes-Benz models.
Why Is a B3 Service So Expensive?
If you own a Mercedes-Benz, you may wonder why the B3 service seems quite expensive. Why is the price so high?
When compared to A-services (A1, A2, A3, etc. ), B-services (B1, B2, B3, etc.) are more comprehensive. It’s because of this that last year, you paid quite a bit less for A3 service.
A Mercedes-Benz vehicle is designed with sophisticated technology, high-quality parts, and complex systems, which require specialists to diagnose and repair. B3 services ensure that your vehicle remains in top condition by leveraging their expertise.
As well as that, Mercedes-Benz’s exclusivity influences service costs. In terms of performance, comfort, and innovation, Mercedes-Benz is renowned as a luxury brand.
These brands deliver a premium experience with their cars (like Audi, BMW, and others), as well as high levels of service and maintenance. Consequently, maintenance is also expensive.
In a nutshell, the cost of maintaining a Mercedes-Benz B3 service is part of the luxury brand’s total cost of ownership. If you need to find a mechanic in your area who knows Mercedes, it is best to find one who is a trusted mechanic. In addition to saving money, you’ll often receive more individualized service.
How Often Should a B3 Service Be Performed?
These services typically need to be done after 60,000 miles (or 6th year of ownership). The car’s Flexible Service System will determine the EXACT time. Once the A3 service has been completed, it will take approximately a year (or 10,000 miles).
When it comes time for you to perform the B3 service, your car will display a message such as “B3 Service Due“, “B3 Service Exceeded by X Days“, “Service Code: B3“, or “Service B.” You shouldn’t worry if you don’t remember the exact date.

Choosing the Right Service Center
Authorized Mercedes Service Centers
Identifying certified Mercedes-Benz service centers should be your first step. The certification confirms that the service center has undergone specialized training from the manufacturer, ensuring it has the technical know-how and tools needed to work on Mercedes vehicles. Since these centers are equipped with up-to-date information and tools, they are likely to provide high-quality service B3.
Customer Reviews and Testimonials
Evaluation of the service center’s reputation is an essential part of your research. Through reviews and ratings, digital platforms allow customers to share their experiences.
Find service centers that boast a high level of customer satisfaction, particularly comments that highlight their professionalism, work quality, and commitment to the customer.
When the customer completes the purchase, presenting beautiful car-themed Pin Badges increases the customer’s goodwill value. Also, pins with the service center’s logo as a gift will be a good way to promote the event. Having a wide variety of badges as gifts during an event is also a way to gain customer favor..
Centers with a strong Mercedes track record
In the field of automobile service, experience is crucial. In order to serve vehicles of various make and models, long-established service centers tend to accumulate comprehensive knowledge and expertise, which enables them to handle intricate service requirements, such as Service B3, with the best efficiency.
Get An AASE-Certified Mechanic To Work On Your Vehicle
They have passed rigorous tests and acquired professional experience in a variety of areas related to vehicle maintenance and repair.
Use of Genuine Parts
Replacement parts during Service B3 should only be performed by qualified Mercedes-Benz service centers. It is important to use genuine parts to maintain the performance and resale value of your vehicle. Authentic parts ensure the perfect fit and functionality.
Communication and transparency
Customer communication is the key to a good service center. If you have any questions about the Service B3 procedures, they should be able to provide clear explanations.
How Long Does a B3 Service Take?
Typically, Mercedes B3 servicing takes between 2-3 labor hours, but it can vary a lot depending on its location, season, and maintenance requirements.
Independent specialists cannot compete with dealer shops with trained mechanics and streamlined processes. The labor rates of independents, however, are usually lower. Overbooked shops may experience longer wait times during busy spring and fall seasons.
Lastly, a shop’s staffing level also impacts turnaround time. The B3 checklist will not cover all maintenance requirements, so adding more requirements will add more time to the maintenance process. It may only take 2-3 hours to complete the B3 service alone, but once shop delays, seasonal demands, and any additional maintenance are taken into account, the total time may exceed 3 hours.
Can I Do a B3 Service Myself?
These services can be performed by you yourself. It is important to consider a few factors before taking on this project.
To begin with, ensure that you have the necessary tools, knowledge, and skills. Oil changes, air filter replacements are novice-friendly (e.g., oil changes) while spark plug replacements, brake fluid changes require more expertise and tools (e.g., brake fluid changes).
Performing a service on your car effectively requires knowledge of its functions and components. Several resources can provide you with information about these aspects, including specific model-specific service manuals, forum postings by users, YouTube videos, and even the owner’s manual for your vehicle.
The second thing you should know is that doing a B3 service yourself carries some risks. If you’re not careful or experienced in performing the required tasks, you may make mistakes or even damage your car.
Additionally, performing a B3 service yourself could void your warranty. For a complete understanding of the implications of performing the service on your own, be sure to read the terms and conditions in your car’s warranty. A non-authorized professional may void some warranties.
Do-it-yourselfers can provide B3 service but must consider their skills, the tools they have available, the risks they may face, and any terms of use that may apply. While you will save some money, you should know that Mercedes-Benz parts are not exactly cheap, so while you will save some money, you won’t be able to afford it.
