You will learn exactly what the B8 service includes, why it matters, and what you can expect in terms of costs in this article.


What Is a Mercedes B8 Service?

To maintain Mercedes-Benz vehicles smoothly and reliably, a B8 service is recommended. In addition to keeping your vehicle in top condition, the B8 service is part of the Flexible Service System (FSS).

It’s important to keep up with the maintenance schedule by performing the B8 service. Taking care of this now will help to prevent costly repairs down the road and will allow you to enjoy your ride more now.


When Should a B8 Service Be Done?

Mercedes-Benz vehicles typically require a B8 service between 160,000 and 200,000 miles, or approximately one year after their last A8 service. Congratulations on making it this far. Your vehicle has clearly been well taken care of.

When Should a B8 Service Be Done?

Your car probably tells you when B8 service is due unless you’ve just bought it. Since your vehicle will already remind you, you won’t have to worry about setting reminders on your calendar if you’re new to the Benz family.


What Does a B8 Service Include?

Mercedes-Benz owners should not neglect the B8 service on their maintenance checklist. The B8-specific services are included in the “major” maintenance activities in the overall maintenance schedule.

What Does a B8 Service Include

Automatic Transmission Fluid Replacement (B8 Specific)

It is more important to replace the automatic transmission fluid during the B8 service of your Mercedes-Benz than it initially appears to ensure the transmission runs smoothly and efficiently.

Dirt and debris can contaminate transmission fluid, leading to decreased performance and possible transmission system damage. Fluid replacement removes any contaminants and buildup that hinder transmission performance.

Automatic Transmission Filter Replacement (B8 Specific)

With a B8 service, you replace your transmission fluid with a new one and remove the old transmission filter.

Similarly to other types of filters, transmission filters trap dirt and other contaminants to prevent them from entering sensitive areas. Filters clog up over time and restrict transmission fluid flow. You run the risk of a blown transmission not only from overheating, but also from overuse.

Clean and Degrease Sunroof Guide Rails (B8 Specific)

Clean and degrease the sunroof’s guide rails as part of a B8 service, which is often overlooked.

The runners of your mobile skylight can get caked with crud and gunk over time, which bogs it down. No worries, a Mercedes technician can clear those tracks so that your roof opens smoothly again. It also prevents costly repairs in the future by keeping those rails primed and free of grime.

Replace Synthetic Motor Oil (Standard B-Service)

As part of any routine maintenance visit on your Mercedes, the engine oil is changed during a B8 service.

Due to its slower breakdown rate than conventional oil, Mercedes-Benz uses full synthetic oil exclusively, allowing oil changes every 10k miles.

When motor oil is not used properly, it becomes less effective at lubricating moving components and can cause friction and harm to moving parts over time. Keeping your engine’s lubricating conditions optimal is made easier with fresh synthetic oil.

Replace Oil Filter (Standard B-Service)

B8 services include replacing the engine oil as well as the oil filter. Using this filter, particles and contaminants are captured, so they cannot circulate within the lubrication system.

Clean oil flows freely without being contaminated by harmful debris thanks to a new filter.

Replace Cabin Air Filter (Standard B-Service)

Dust and pollen are trapped by the A/C filter in your car before they enter the cabin. Air quality and HVAC operation suffer as it becomes congested with use.

Hence, the B8 service (or any “B” service for that matter) involves replacing this filter – so that you’ll be breathing clean, filtered air on a regular basis.

Check Fluid Levels (Standard B-Service)

You will have your Mercedes’ fluid levels checked and refilled as part of the B8 service. In addition to transmission fluid, it is important to check power steering fluid, brake fluid, and windshield washer fluid.

Filling your vehicle with the right level of fuel maximizes its performance and extends its life. The technicians will make sure the fluids are properly checked and replenished.

Check Tire Pressure (Standard B-Service)

Maintaining your car requires you to pay attention to tire pressure. In addition to checking your tires’ pressure, a B8 service also includes a spare tire check.

Saving money on fuel and preventing problems like uneven tire wear and reduced handling capabilities can be achieved by implementing this simple step.

Check Brake Components (Standard B-Service)

Your brake components are carefully inspected during the B8 service. In addition to checking the rotors and calipers, the technician also checks the pads.

The complete braking system is also checked for proper operation. Your Mercedes’ brakes will be inspected during this inspection to ensure they are in good working order.

Mercedes B8 Service Cost

Have you ever wondered how the B8 service runs on your Mercedes? You can expect to pay anywhere from $700 to $1,400 for the official dealer options. The cost may seem high, but you’re getting factory parts and expert technicians.

It is important to read the warranty terms carefully before skipping the dealer. Maintenance matters more than cost. Your Benz will last longer if you maintain it regularly.

Find a dealer or indie you trust, regardless of whether you prefer peace of mind or value. When you have your Benz serviced properly, you can rest assured that it is being taken care of properly.


Why Is a B8 Service So Expensive?

It’s not the first time you’ve wondered why a Mercedes-Benz B8 service is so costly. However, there are a few reasons for this:

  • Mercedes is considered a luxury brand with a prestige image. Due to its prestigious reputation, the company can charge premium prices for new vehicles and scheduled maintenance.
  • Numerous maintenance items are covered by the comprehensive B8 service. There are some repairs that are extremely labor-intensive or require a lot of parts, such as the replacement of transmission fluid.
  • Identifying and fixing issues properly requires expensive diagnostic tools and shop equipment. Consumers pay for these costs.
  • There is a comprehensive training program and certification program for Mercedes technicians. Compared to independent repair shops, they charge a higher hourly rate because of their specialized experience.
  • In order to optimize precision vehicle performance, Mercedes uses high-quality parts and fluids made in Germany. Compared to aftermarket materials, these premium-quality materials are more expensive.

How Long Does a B8 Service Take?

There are a number of factors that can affect how long you spend at the shop for a Mercedes B8 service, but it can range from as little as two hours up to four hours (or more).

In addition to the appointment load, staffing levels play a huge role in the success of the shop. If facilities are overburdened with appointments scheduled close together during the busy spring and fall seasons, the time needed might be extended. Earlier services that ran long may also delay later appointments if they ran late.

How Long Does a B8 Service Take?

B8 services can often be completed quicker in large or well-staffed shops because more techs and service bays are available. The delays could occur even if no additional repairs are required in a shop that is understaffed and overbooked.

As a result of real world variables such as staffing issues, shop delays, seasonal demand, and unforeseen maintenance issues that are uncovered, it can take up to four hours for some B8 services to be completed when performed by experienced technicians.


Can I Do a B8 Service Myself?

It is unlikely that most Mercedes B8 owners will be able to perform certain aspects of maintenance themselves, especially if they have an AMG model.

To accurately implement factory procedures, an intricate maintenance process requires specialized tools, diagnostic software, and a certain level of expertise.

Can I Do a B8 Service Myself?

An improperly performed repair can cause a dangerous mechanical failure, more costly repairs later, or void your warranty if you do not have the proper training.

Although it is more expensive, owners should pay authorized Mercedes technicians due to the complexity involved. DIYing may save money for those who are experienced in servicing Mercedes specifically if they are prepared to maintain factory standards.
