Mercedes-Benz B maintenance includes the following items: changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. The vehicle maintenance cycle is divided into two indicators: one is a time indicator, and the other is a mileage indicator. The specific maintenance schedule should be determined based on the vehicle's usage. The replacement of engine oil and oil filter is mainly for the maintenance of the lubrication system. The primary function of the vehicle's lubrication system is to lubricate various internal components of the engine to prevent excessive wear during operation. It is important to note that during the oil change process, the oil filter should also be replaced. The oil filter's function is to remove various impurities from the oil, ensuring the lubrication system operates properly. Under normal driving conditions, the engine oil and oil filter should be replaced every 5,000 kilometers. Mercedes-Benz is a German luxury car brand renowned for its perfect technical standards, high-quality benchmarks, innovative capabilities, and a series of classic coupe models. The Mercedes three-pointed star has become one of the world's most famous automotive and brand logos.

As someone who frequently drives long distances, I pay special attention to maintenance details. For Mercedes-Benz B-service, besides basic operations like oil and filter changes, they thoroughly inspect the brake pad thickness to determine if replacement is needed—safety comes first, after all. The cabin air filter must be replaced, otherwise, odors can easily develop in the car. All chassis bolts are re-tightened, as loose ones can cause rattling noises at high speeds. The free top-up of windshield washer fluid is a thoughtful touch, and they’ll proactively remind you to replace worn wiper blades. Finally, the technician will perform a full vehicle scan for fault codes using a diagnostic computer, even checking the battery health. The entire process takes about two hours. Remember to ask them for a test drive after maintenance—sometimes rattles only appear at specific speeds.

My Mercedes gets the B-service done every year, and the package is quite substantial. They use a dedicated low-ash engine oil during the change, which is gentler on the engine. The key focus is the comprehensive inspection: brake fluid gets replaced if moisture content exceeds 3%, and tires are removed to check inner wear. Air filters are replaced immediately if dirty—after all, they affect engine breathing. Most crucially, every light gets inspected, down to the license plate bulbs. Last time, they found my rear parking sensor was mud-caked; cleaning it made reverse parking much safer. I could monitor the whole process from the lounge, and they even washed the car post-service.

Just completed the B-service, which is much more detailed than the A-service. Changing the engine oil and filter is the basic operation, but the key point is that they used a flashlight to inspect every corner of the chassis. They checked if the brake discs had grooves and whether the suspension bushings were cracked. The spark plugs were removed to inspect electrode wear, and at around 60,000 kilometers, they generally need replacement. The washer fluid reservoir connector tends to age and leak, a critical inspection item many overlook. Finally, while upgrading the infotainment system, the technician found that one of my tire pressure monitoring sensors had a weak battery, so it was replaced in advance to avoid a midnight alert.
