Why Should I Get a Mercedes B4 Service?
It’s important for Mercedes-Benz owners to take care of their vehicles so that they will perform well for many years to come. Mercedes-Benz’s Flexible Service System (FSS), which separates maintenance intervals according to daily mileage, duration, and level of use, makes the B4 service one of the most cost-effective and convenient services on the market.
Every 10,000 miles (or 12 months), Mercedes offers minor (A) and major (B) services alternately. As long as you keep up with your schedule, the FSS will determine the exact times for you.
It can be said that the B4 service in the maintenance schedule follows on from the A4 service; it is the 4th major service in your vehicle’s lifetime.
An additional three items are added to a B4 service compared with other scheduled services that do not include these additional items.
What is the best time to perform a B4 service?
The B4 service is performed on Mercedes vehicles between the 80,000 mile mark and approximately one year after the A4 service has been completed, which is typically the eight year mark after ownership and after the completion of the A4 service.
Please don’t worry if you forget to maintain your car at the exact time. There’s a message telling you when it’s time to service your car. It may say “B4 Service Due”, “B4 Service in 30 Days.
What is included in a B4 service?
There are a variety of standard B services as well as specific B4 services that make up a comprehensive maintenance package. An average B4 service consists of the following tasks.
Replace Air Filter
A B4 service includes replacing the air filter as one of the major tasks. It’s important to keep the air flowing well, which improves performance and fuel economy.
Air filters can affect engine efficiency and power if they’re too dirty or clogged. The best way to prevent a vehicle from getting damaged is to take good care of it.
Replace Spark Plugs
Spark plugs play an important role in the ignition of fuel-air mixtures in engines.
You get a B4 service that checks and replaces spark plugs to avoid misfires, rough idling, and general power loss that results in less than comfortable driving.
Clean Sunroof Rails
To keep your Mercedes’ sunroof operating smoothly and quietly over time, make sure you clean the guide rails and degrease them regularly. It may get sluggish or noisy when the sunroof opens or closes as the rails collect dirt, debris, and grease.
Your sunroof will function as if you originally purchased it when you have a B4 service performed on it. This is because any dirt or buildup obstructs the sunroof’s movement is removed. As part of this regular maintenance, the motor and other components of the sunroof will also be protected against damage, which can prove costly in the future.
Replace Synthetic Motor Oil
Any routine maintenance service includes changing the engine oil (a B4 service is no different). Full synthetic oil is the only oil Mercedes-Benz uses, so oil changes are spaced out over 10k miles instead of 5.
Using motor oil for a long period of time leads to increased friction and the possibility of damage because it loses its ability to effectively lubricate moving parts. Maintaining optimal lubrication conditions for your engine can be achieved by using fresh synthetic oil.
Replace Oil Filter
During a B4 maintenance visit, the engine oil and oil filter are exchanged. As a result of this filter, lubrication systems are prevented from becoming clogged with impurities.
Clean oil stays cleaner for longer when it is filtered.
Replace Cabin Air Filter
Pollen, dust, and pollutants are prevented from entering your car’s cabin by its cabin air filter. As a result, it can become clogged over time, resulting in poor air quality inside the cabin and lack of efficiency with the HVAC system.
You and your passengers can breathe clean, filtered air with the B4 service that replaces this filter.
Check Fluid Levels
In addition to checking all of your Mercedes’ fluid levels, technicians will add additional fluid as necessary during a B4 visit. A variety of fluids are checked, including transmission fluid, coolant, power steering fluid, brake fluid, and windscreen washer fluid.
For your vehicle to function at its best and last as long as possible, it is imperative that each fluid is kept at the proper level. The service team will ensure that they are inspected and filled properly.
Check Tire Pressure
In a B4 service, you’ll get a tire pressure check, among other things. To keep your tires running efficiently and extend their lifespan, you need to keep them inflated to the recommended pressure.
Uneven tire wear and reduced handling are some of the consequences of not doing so.
Check Brake Components
An inspection of key brake parts is carried out by the technician during a B4 service. In addition to inspecting the rotors, calipers, and brake pads for wear, they will test the entire braking system as well.
You can keep your brakes safe and efficient by performing this thorough examination.
Mercedes B4 Service Cost
There are a few options when it comes to a B4 service for Mercedes. Going to an authorized Mercedes-Benz dealership is the most expensive but most reliable route. Prices vary according to model and location, but you can expect to pay between $800 and 1,600.
Although dealership technical support is pricey, Mercedes-Benz parts are genuine and the technicians are factory-trained. As the manufacturer does not want to lose you as a customer, if anything goes wrong, they will be much easier to work with.
Alternatively, if you are looking for something more budget-friendly, you might consider hiring a Mercedes-Benz or European mechanic. Reading customer reviews and thoroughly screening them will ensure you receive quality service.
