What does Mercedes-Benz B4 maintenance mean?
2 Answers
Mercedes-Benz B4 maintenance refers to the 40,000-kilometer maintenance for the Mercedes-Benz B-Class. Below is a relevant introduction about car maintenance: First maintenance: Some manufacturers will set the first maintenance based on time or mileage, and the exact timing should be referred to the vehicle's user manual or warranty manual. The first maintenance is very important and free, so be sure to remember to do it to avoid missing it and affecting the car's third maintenance. Maintenance items: The main maintenance items for a car include replacing engine oil, oil filters, transmission fluid, spark plugs, cabin air filters, engine air filters, brake fluid, etc. However, not all items need to be replaced every time, as it depends on their service life. In addition, maintenance also involves inspections and servicing of dozens of items across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires.
As a car enthusiast who often helps friends with car purchases, the Mercedes-Benz B4 service is actually a standard maintenance package code. B stands for basic maintenance, which primarily involves changing the engine oil and oil filter—a must-do every 10,000 kilometers or one year. The 4 refers to a set of additional items, typically including replacing consumables like the air filter and cabin air filter. When I perform maintenance myself, I pay special attention to the cabin air filter, as it directly impacts interior air quality and cooling efficiency. Additionally, the service includes 18-point inspections such as checking brake fluid moisture content and tire condition. Although it's called basic maintenance, Mercedes-Benz's inspection items are quite comprehensive. I recommend sticking to the schedule, as German cars tend to develop minor issues if maintenance is neglected over time.
