Mercedes-Benz's B items: 1. Engine oil level check: Park the vehicle on a level surface. Pull out the dipstick to check the oil level; if the level is between the (F) and (L) marks, it is within the normal range. 2. Engine coolant level check: When the engine is hot, never open the radiator cap, as you may be scalded by splashing coolant or high-temperature steam. 3. Brake fluid level check: The brake fluid level should be between the high and low marks to be considered normal. 4. Clutch master cylinder fluid level check: The clutch fluid level should be between the high and low marks; if it is below the standard line, the master or slave cylinder seals may be damaged. 5. Battery maintenance check: Check if the battery is securely fastened; the electrolyte level should be between the upper and lower limits. If it is close to the lower limit, promptly add electrolyte or distilled water to reach the upper limit. 6. Tire check: Check the tire pressure monthly at normal temperature; if it is below the standard, promptly inflate the tires. 7. Belt check: If the belt makes noise when starting the engine or during normal driving. 8. Spark plug check: A normal spark plug has intact insulation ceramic without cracks or leakage. The spark plug gap should be 0.8±0.0mm, and the spark should appear blue and strong during discharge.

















Speaking of Mercedes-Benz's B-service, as a long-time owner who has driven a Mercedes for over a decade, I'd like to share some insights. The B-service is typically performed every 20,000 kilometers or once a year, and it's much more comprehensive than the A-service. It primarily includes an oil and oil filter change to keep the engine running smoothly. The air filter and cabin air filter also need replacement to prevent unpleasant odors inside the car. Checking the brake system is crucial—inspecting brake pad wear and fluid levels to avoid skidding in emergencies. Additionally, tire rotation and balancing are essential; while Mercedes has excellent chassis tuning, neglecting this can lead to uneven wear. Suspension checks and electronic system diagnostics are also mandatory—Mercedes' computer systems are complex, and early detection of issues saves money. I recommend sticking to authorized dealerships for service; though pricier, they're reliable, and proper helps retain the car's value. In short, the B-service is a major preventive measure—don't delay it, safety comes first.

From a technical enthusiast's perspective, the B-service pays great attention to details. The checklist generally includes: oil and filter replacement for basic engine lubrication. Air filter renewal prevents intake blockage. Cabin air filter replacement ensures fresh cooling. Brake system inspection covers disc/pad wear and hydraulic testing to enhance braking response. Tire service involves rotation and balancing to extend lifespan. Spark plugs require inspection every 40,000 km for smooth ignition and fuel efficiency. An OBD system scan is necessary as Mercedes diagnostic codes may hide faults. It's recommended to follow the maintenance alerts on the Mercedes app to avoid oversight. The B-service should be performed annually or every 20,000 km at authorized workshops for peace of mind - DIY part replacements may cause issues. These cumulative minor services significantly reduce unexpected repair risks.

As a practical car owner, I say the key items for B-service are: changing the engine oil, air and cabin filters to maintain good air quality inside the car. A comprehensive brake system check ensures safety and prevents slipping. Tire wear inspection and rotation for stable driving. Replace spark plugs if aged, for better fuel efficiency and smooth performance. Electronic diagnostics and suspension tests are essential—Mercedes has advanced tech, and issues can have big impacts. Recommended every year or 20,000 km, best done at an authorized dealer for reliability. Don’t skimp—it prevents major repairs and gives peace of mind.

I've tried DIY car before, but the Mercedes-Benz B-service items require serious attention. The basics are oil and filter replacement, but Mercedes-Benz designs are intricate, and self-disassembly can lead to mistakes. It also includes replacing the air and cabin filters to improve the breathing environment. A thorough inspection of the brake system is necessary, checking disc thickness and fluid levels. Tire balancing and rotation prevent uneven wear. The timing for spark plug replacement depends on mileage to optimize performance. Mercedes-specific items like transmission fluid checks require professional tools. It's recommended to have the B-service done at an authorized dealership—though costly, it's worth it, performed every 15,000-20,000 km to save money in the long run and keep the car in excellent condition.

Daily driving a , the B-service covers comprehensive items. The main tasks include engine oil and oil filter replacement, which are the core of engine maintenance. Air filter and cabin filter renewal ensure fresh air during travel. Brake system inspection guarantees responsive and safe operation. The tire section involves rotation and balancing to enhance grip. Spark plug diagnosis and replacement are performed if worn out, as they affect ignition. Electronic and suspension tests prevent faults in the complex Mercedes systems. The service is recommended approximately every 20,000 kilometers at an authorized dealership for standardized and worry-free maintenance. Timely upkeep extends the vehicle's lifespan and ensures steadier performance on highways.
