Mercedes-Benz Service B in Bloomington, MN
What Service B includes, what the B codes mean, and how to know what your Mercedes-Benz is actually due for. From the factory-trained team at Feldmann Imports.
Mercedes-Benz Service B: Starting at $725
Price advertised for Service A/Service B includes all factory-required components. Please refer to your maintenance booklet for the complete list of factory-required services and details on the specific intervals for your vehicle’s year and model. Price varies on 2014 S-Class.
What the A and B service codes mean
Every modern Mercedes-Benz tracks its own maintenance through the ASSYST Plus system, which watches time, mileage, and driving conditions rather than a fixed schedule.
- Service A is the lighter, alternating visit, centered on an oil and filter change and a standard inspection.
- Service B is the more involved visit that adds a cabin filter, a full multi-point inspection, and additional interval items.
- The number after B tells you which additional items are due at that visit, not how big the service is. More on that just below.
What the number after the B means
This is the part most drivers, and even some shops, get wrong. A B7 is not a bigger service than a B3. The number is not a ranking. It simply tells you which additional maintenance items happen to come due at that visit, based on your car's age and mileage.
Two things are on almost every visit: a full major inspection and an engine oil and filter change. Everything the number adds sits on top of that. Codes run from B1 through B9 and beyond, and the exact combination depends on your model, engine, and mileage.
| Additional item the code may flag | Roughly when it comes due |
|---|---|
| Brake fluid exchange | About every 2 years |
| Engine air filter | Higher mileage intervals |
| Fuel filter (diesel) or spark plugs (gas) | Higher mileage intervals |
| Transmission fluid and filter | Higher mileage, model dependent |
| Engine coolant renewal | Longer interval item |
| Sunroof track service (if equipped) | Periodic |
This is what the codes can add, not a guaranteed list for your car. The exact items on your Service B are set by your VIN. Give us your code or your VIN and we will tell you precisely what is due, with nothing padded on.

Received a service estimate? How to read it
If you have just been handed a service estimate, the question is usually simple: is this fair, and is all of it actually due? Here is how to read it.
What drives the cost up
- Brake fluid exchange coming due
- Multiple filters at the same visit
- Spark plugs on certain engines
- Transmission service on some models at higher mileage
Questions worth asking about any estimate
- Which items are due by time or mileage versus found on inspection?
- Can you show me the measurements (pad mm, tread, battery test)?
- Are any add-ons duplicative for my model?
- Will the ASSYST Plus counter be reset correctly for my exact code?
Why Service B belongs at the dealer
You are not driving a generic car, and a Mercedes-Benz Service B is not a generic oil change. The right service depends on factory data, factory software, and factory parts matched to your exact VIN. That is the difference between a shop that changes your oil and a team that services your Mercedes-Benz the way Mercedes-Benz intended.
- Your warranty stays protected. An authorized service history keeps your factory and extended warranty coverage clean, and opens the door to goodwill assistance if you ever need it.
- The service system is reset correctly. Reading your code and resetting ASSYST Plus for your exact vehicle takes factory-level tools. Done wrong, your future service timing is thrown off.
- Open software and recall campaigns get handled. We see and perform the factory software updates and service campaigns on your car that a general repair shop simply cannot access.
- Only genuine Mercedes-Benz parts touch your car. Factory filters, fluids, and components matched to your VIN, never a generic substitute.
- Your resale value is documented. A complete authorized service history is one of the strongest levers on what your Mercedes-Benz is worth when you sell or trade it.
Factory-trained technicians, genuine parts, and a documented history are not extras on a Mercedes-Benz. They are the standard your car was built to.

When does a Mercedes-Benz vehicle require Service B?
Mercedes-Benz Service B is typically required at the 20,000 mile mark or 2 year interval, whichever occurs first. Moving forward, Service B intervals alternate with Service A, meaning you will generally schedule a Service B appointment every 20,000 miles or 2 years after your last one. Your ASSYST Plus display is the accurate source for your driving pattern.
Why is a brake fluid flush included in Mercedes-Benz Service B?
Brake fluid is naturally hygroscopic, meaning it absorbs moisture over time from the surrounding environment. This moisture accumulation can lower the boiling point of the fluid and lead to internal component corrosion or reduced stopping power. A complete brake fluid flush during Service B restores proper braking performance and protects the system.
What is the advantage of using genuine OEM components for Service B maintenance?
Genuine Mercedes-Benz parts and fluids are matched to your exact vehicle by VIN, which protects performance, preserves your warranty position, and supports resale value. Generic equivalents are not guaranteed to meet the same specification.
What does the number after the B mean, like B4 or B5?
The number flags which additional maintenance items are due at that visit, such as brake fluid, an air filter, or spark plugs. It does not mean a bigger service, so a B5 is not automatically more than a B3. The exact items depend on your model, engine, and VIN, and we can confirm precisely what is due from your code.
Why does the starting price for Service B differ from Service A?
Service A is the lighter alternating visit, while Service B adds a cabin filter, a full multi-point inspection, and additional interval items. Because Service B includes more work, it starts at a higher price than Service A.
How can I confirm if my vehicle currently needs Service A or Service B?
Your ASSYST Plus display in the instrument cluster shows the service code and how soon it is due. For the exact line items on your specific vehicle, our service team can confirm everything by VIN.
