In Mercedes, the B3 code indicates that some services are specifically addressed in the code. Maintaining your Mercedes-Benz through routine maintenance is essential to ensuring its longevity and performance.
There are, however, some Mercedes-Benz owners and drivers who require assistance in getting accurate and relevant information regarding the B3 Service code displayed on their vehicle’s instrument panel.
Using this maintenance Minder, the owner is alerted to the fact that a service is due and must be recovered. My questions regarding various messages were also clarified one and a half years ago.
The purpose of this article is to provide information about Service B3 Mercedes. As I observe and experience that code personally, I am expressing my observations and journey. Among other factors, you’ll gain a detailed understanding of its meaning and cost.
How Does Mercedes Service B3 Work?
This service package is designed to ensure your Mercedes vehicle’s long-term health and peak performance by combining the standard B service with additional specialized tasks.
A Mercedes vehicle’s B3 service is typically recommended around the 60,000 mile mark or at the 6 year mark, although the precise timing may vary depending on the vehicle’s Flexible Service System. To maintain your Mercedes’ luxury, performance, and longevity, you need to perform the B3 service at the appropriate intervals.
What is the best time to perform a B3 service maintenance?
It is recommended that your Mercedes is serviced after the sixth year or after 60,000 miles, depending on the model. After the A3 service is completed, it usually takes 10,000 miles or a year.
There is no difference in the criteria for Benz models, but they can vary a bit based on the model, such as the C250, the E350, the ML350, the C300, or the GLA. As well as fluid level checks and brake inspections, there are other sub-services involved.
Your vehicle feels better on the roads after a service, and ignoring that maintenance puts you at risk of low engine performance and costly repairs.
In any case, it is important that B3 is serviced on its due date. As a result, the car’s safety can be extended, quality can be improved, and costs can be reduced.

You can do the service yourself with this checklist rather than going to the garage.
| Service Item | Type | Cost-range |

| Replace Spark Plugs | B3 Exclusive | $100 – $300 |
| Replace Synthetic Motor Oil | Standard B-Service | $120 – $250 |
| Replace Oil Filter | Standard B-Service | $15 – $70 |
| Replace the Cabin Air Filter | Standard B-Service | $40 – $110 |

What are the items included in Mercedes Service B3?
The following is a list of the detailed themes that are included in B3 Service. In order to maintain your car’s overall health, these items must be serviced on time.
Spark plug service
Having the comfort of a Mercedes-Benz makes your trip more exciting and adventurous. The spark plug can fail if the vehicle is driven at a very low speed or if it is idled for long periods of time.
During this service, your mechanic inspects and replaces your car’s spark plugs if they need to be replaced. The air filter was also replaced (required) and injection system was overhauled to prevent further damage to the vehicle.
Spark plug inspection is one of the most important aspects of B3 maintenance.
It is therefore important that you replace your spark plugs whenever your car’s engine has a rough idle or misfires.
Air Filter Replacement
In addition to improving engine performance and airflow, air filters also reduce fuel consumption. The power and efficiency of Mercedes-Benz engines are reduced by clogged air filters.
An air filter is inspected and replaced with a new one during a Mercedes Service B3 appointment. As a result of the newly installed filter, the engine will be able to run at its most efficient and stop the dust from entering.
Inspection of brake components
There is a direct correlation between brake components and road safety. Mercedes’s pressure transmission will be obstructed by brake fluid leaks.
In addition to the fluid, brake pads, brake lines, and shoes, a detailed inspection is performed. An extensive check makes it possible to detect any malfunctions before they lead to more serious damage.
Disc depreciation will cause the Mercedes brakes to fail as well. It is therefore essential to get routine maintenance in order to prevent such bad situations from occurring.
Replacement of synthetic motor oil
In Mercedes Service Code B3, it is important to replace the synthetic motor oil. For optimal engine performance, Mercedes-Benz models require oil changes every 10,000 miles (once a year).
It will be necessary to remove the old oil, and to replace it with new oil during that maintenance. Heat is distributed evenly throughout the engine thanks to the new oil, which prevents the engine from overheating.
In order to protect your engine from extreme weather, you should use synthetic oil instead of regular oil. Regular oil cannot withstand extreme temperatures. You should get synthetic oil from a Mercedes dealer who is authorized and experienced.
Check the availability of all other fluids
There are several parts in Mercedes Benz cars that require different fluids in order to function efficiently. If these fluids leak, the components will stop working and cause problems.
As a result, fluid checks and corrections are an important part of the B3 service. Depending on the model, year, and interval of your car, you might need to perform these checks and corrections. Also, I recommend reading the owner’s manual.
What is the cost of servicing a B3 Mercedes?
You may need to pay a lot more or less for the Mercedes-Benz B3 service based on several factors, including the model of your car, the location of the garage, and the labor rate. Nevertheless, the cost of that code can range from $200 to $450 on average.
When a Mercedes model reaches 20,000 miles, it receives the B service. There are three main items to be replaced as part of that service: the air filter, the spark plug, and the oil. In addition, other small services can be performed with only a base requirement.
| Service | Cost-range |
| Air Filter Replacement | $50 to $150 |
| Spark Plugs Replacement | $100 to $300 |
| Synthetic Motor Oil Replacement | $120 to $250 |
Is it possible to perform B3 service maintenance myself?
You can also have B3 services performed on your behalf. In order to complete this process, a few simple steps need to be followed.
The maintenance must also be performed by someone who has the necessary knowledge and expertise. There are also some tools that are required for the performance of different tasks. For that service, it is necessary to have the following tools:
Tools required for B3 service
There are some necessary options for Spark Plug Replacement depending on your Mercedes-Benz.
- Manual for owners

There are certain maintenance services that are easy to perform, and any car owner can complete them without interruption. If you want to fix other issues, you will need the tools and knowledge I mentioned.
The risks of self-servicing the Mercedes B3
It can be risky to perform that service on your own. When you are inexperienced and are performing tasks carefully, you may make a mistake, and this may result in significant damage.
As a result, your vehicle’s warranty may be affected as well. If you have a garage at home, you may also perform this service. My recommendation is that you hire an expert with repeatable delays for B3 service based on my experience and our research.
What Are The Methods For Resetting Mercedes Service B3?
Method 1: Begin 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.
Method 2: Select the ‘Trip’ menu
By pressing the left navigation button, you will see the “Trip” menu. While holding down the call button, hold down the “OK” button for about five seconds.
The shop menu will appear when you click this button. You can find “Trip” by scrolling down.
Method 3: Select ‘Assyst Plus’
By repeatedly pressing the down navigation button, you will find the “Assyst Plus” option. Click “OK” to confirm.
You will now be able to select “Full Service” and “Service Data”. Once you have selected “Full Service”, click the down arrow again and click “OK”.
With the down arrow, scroll down until you reach “Conf”. Scroll down to “Full Service”. Choose what you want. You will then be asked, “Service completed? ”.
In order to confirm your selection, click the down arrow and choose “Yes ”.
Method 4: Complete the process
You will see the message “Cannot be done.”. Click on the down arrow until the word “Confirm” appears. As soon as you understand, 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?”.
The process is complete once you click “OK”. The system needs to be confirmed at each step in order to function.
Some Mercedes models may not be compatible with this reset, depending on the model year.
What is the average turnaround time for a B3 service?
As a rule of thumb, Mercedes B3 servicing takes between 2-3 labor hours, but that can vary a lot depending on the model, location, and season.
Dealership shops with skilled mechanics and streamlined processes cannot compete with independent specialists. Independent contractors, however, typically charge lower labor rates. During busy seasons such as spring and fall, overbooked shops may experience longer wait times.
Finally, the level of staffing in a shop plays an important role in determining turnaround time. Maintenance requirements are not covered entirely by the B3 checklist, so adding more requirements will increase maintenance time.
When shop delays, seasonal demands, and additional maintenance are taken into consideration, it may require more than three hours to complete the B3 service alone.
