What does Mercedes-Benz Maintenance A and B include?
3 Answers
Mercedes-Benz maintenance categories are as follows: A Maintenance: Engine oil, oil filter, lubrication maintenance, windshield washer fluid top-up, full vehicle fluid inspection, computer diagnostics, drainage system check, tire tightening, tire pressure (5 tires), chassis inspection (including suspension, brake discs, pads, and all chassis components), interior inspection (horn, headlight washer, seat belts, interior lights, cigarette lighter, and all functions), battery test, maintenance light and tire pressure light reset. B Maintenance: B Maintenance is performed at 20,000, 40,000, 60,000, and 80,000 (even-numbered) kilometers. It includes replacing engine oil, oil filter, air filter, fuel filter, transmission oil and filter, differential oil, power steering fluid, ABC fluid, brake fluid, cabin air filter, spark plugs, belts, tire rotation, etc.
I previously learned about Mercedes-Benz's Service A and Service B. From my experience, Service A mainly involves basic maintenance, such as changing the engine oil and oil filter, and checking routine items like brake pad thickness and tire pressure. Service B is more comprehensive, building on Service A by adding air filter replacement and a thorough inspection of spark plug condition and chassis suspension components. The two services are typically alternated every 10,000 kilometers. Whenever I visit the dealership, I also ask them to perform an additional battery health check. Following the maintenance schedule as specified in the manual is indeed crucial—it helps prevent minor issues from escalating into major problems. Moreover, a complete maintenance record can enhance the resale value of the car when it's time to sell.
As a long-time Mercedes-Benz owner, I believe the key difference between Service A and B lies in the depth of inspection. Service A is more basic, focusing on fluid changes and fundamental checks, typically completed within an hour. Service B is far more thorough - beyond routine oil changes, it includes air filter removal for throttle body inspection, full-system diagnostic scans, and even sunroof track lubrication. During my last Service B, the technician spotted a cracked CV boot cover and replaced it proactively, saving me from costly major repairs later. Mercedes' dual-tier maintenance system is well-designed, effectively balancing core component preservation with cost control.
