What Includes In The B1 Service?

The health of your vehicle is directly impacted by its maintenance. Being a specialist with over ten years of Mercedes-Benz repair experience, I highly recommend getting the B1 service performed as soon as possible. B1 maintenance therefore includes the following sub-services:

What Includes In The B1 Service
  • Engine oil and filter replacement
  • Fluid level checks
  • Fluid change
  • Brake components inspection
  • Cabin and engine air filter replacement
  • Tire rotation and pressure checks
  • Electrical system inspection

Engine Oil And Filter Replacement

It is as important for the health of the engine to have clean, new oil as for the health of the body. In order to ensure higher quality, the old oil is replaced with high-quality synthetic motor oil during the B1 service Mercedes. 

In addition to changing the oil, the oil filter needs to be replaced as well. Keeping your engine safe and clean for a long time is made possible by oil filters that prevent debris and contaminants from entering your engine. 

It is crucial, however, to follow these two steps at the right time in order to maintain the health and performance of the engine. During the B1 service, synthetic oil provides lubrication and prevents the engine from becoming contaminated with debris.

Fluid Level Checks & Change

In order for any vehicle to run smoothly and last as long as possible, fluid level checks are essential. You should inspect a variety of fluids and their levels in your Mercedes car to make sure it runs smoothly and efficiently. 

Service B1 Mercedes-Benz included inspection and filling of all fluids, including brake, engine coolant, transmission, and power steering fluids. 

The fluid in brakes must be properly maintained to ensure responsiveness. As a result, the vehicle can be protected from mechanical problems that could cost it a lot of money in repairs and be safer while on the road.

Brake Components Inspection

Vehicle brakes play an important role in safety and are an important component of any vehicle. You need to regularly inspect and maintain the brakes on your vehicle in order to ensure safety and reliability.

An inspection of the hole brake system will follow the checking of fluid levels. In order to get impressive brake performance, he makes sure all parts such as brake pad, shoe, rotor, drum, and caliper work well.

Cabin And Engine Air Filters Change

It is important to keep your Mercedes’ air filters clean so it performs optimally and feels comfortable. You can ensure your engine runs efficiently by ensuring it is able to absorb clean air from both cabin and engine air filters. 

Through your vehicle’s air conditioning system (HVAC) and ventilation, cabin air filters the air that enters the engine. In addition to capturing dust, pollen, and other particles, it improves the air quality for passengers. 

As a result of engine air filters, vehicles’ performance and longevity are maintained by preventing contaminants, debris, and dirt from accumulating in the engine. As well as improving the engine’s performance, clean air filters also reduce fuel consumption.

Tire Rotation And Pressure Checks

It’s important to rotate tires and check tire pressure in Service B1 Mercedes-Benz to ensure a vehicle’s safety and capability, as well as to extend the tire’s life.

During service tire rotation, tires are rotated from one side of the vehicle to the other in order to ensure even tire wear. The purpose of this procedure is to improve the overall performance of the tire and help to extend the tire’s life.

For the safety and efficiency of your vehicle, it is essential to check the tire pressure regularly. It is possible for under-inflated or over-inflated tires to cause poor handling, excessive wear, and even blow outs. As a result, it is important and recommended that both tasks are maintained regularly.

Electrical System

The Mercedes-Benz electrical system and its various components are responsible for starting the engine, powering the lights, and operating numerous systems. You need to keep your Mercedes’ electrical system in good condition if you want it to function smoothly. 

A detailed electrical system inspection is performed during the B1 Service in order to identify and replace any faulty electrical components. This can prevent electrical problems and malfunctions in the future.
