B-service includes: engine oil replacement, oil filter replacement, air filter replacement, fuel filter replacement, transmission fluid replacement, filter replacement, differential oil replacement, power steering fluid replacement, ABC fluid replacement, brake fluid replacement, cabin air filter replacement, spark plug replacement, timing belt replacement, tire rotation, lubrication of relevant vehicle components, etc. The benefits of maintenance include: 1. Ensuring the vehicle maintains optimal performance; 2. Improving vehicle efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Keeping the vehicle's appearance clean and preventing damage.

















I remember when my car underwent the B-service, the whole process was extremely detailed. The B-service items mainly include engine oil and oil filter replacement, which are the basic items to ensure smooth engine operation. The air filter is also replaced to prevent dust clogging from affecting air intake. Then the cabin air filter needs to be checked or replaced as well, since fresh air is quite important. Additionally, they thoroughly inspect the brake system, including brake pad thickness and brake disc wear. Tire pressure and tread wear checks are also mandatory to prevent blowout risks. The chassis and suspension system receive a comprehensive diagnosis too, even checking for loose screws. Finally, they use a computer to scan all vehicle fault codes, which is particularly crucial for with its numerous electronic devices. After completing the B-service, the car felt exceptionally smooth to drive. Although the price was a bit steep, safety always comes first.

Last time when I went for the B-service, I specifically observed the checklist. Apart from the basic engine oil and filter replacement, the technician focused on checking whether the brake fluid had deteriorated, which is a major safety concern. They also carefully tested the freezing point of the coolant to prevent winter issues. The tire inspection was particularly thorough, including adjusting the torque of the wheel hub bolts. For the chassis part, they checked for oil leaks in the suspension shock absorbers and any looseness in the steering tie rods. The air conditioning system maintenance was also well done, with the cabin air filter replaced and even the evaporator inspected. Finally, they connected a computer to run a full electronic vehicle diagnosis, including light voltage and chassis module control. The whole process took a whole morning, but the technician had a good attitude, allowing me to wait nearby and observe the operation, which was transparent and reassuring throughout.

I pay close attention to the details of my car, and the brake system inspection takes up a significant portion of the B- items. Last time I went for service, the technician removed the brake pads to measure their thickness and used a flashlight to check the depth of wear grooves on the brake discs. For the chassis inspection, they checked the ball joints and suspension arm bushings, recommending replacements if they showed signs of aging. After rotating the tires, they also performed a free wheel balancing to prevent alignment issues. When replacing the cabin air filter, I noticed the old one was covered in dust, and the airflow improved immediately after the replacement. The electrical system check was quite interesting—plugging in the diagnostic tool made all the dashboard lights flash for a self-test. The entire process was thorough, even checking the rear axle oil level, which left me quite satisfied with the level of detail.

Just had the B-service done last month, let me share the process. The most basic part was of course changing the engine oil and oil filter, followed by key component inspections. The braking system was thoroughly checked, with wear data for both pads and discs printed out for me. Not only was the tire pressure adjusted to standard values, but the wear condition of each tire tread was also marked on the report. When tightening the chassis bolts, the mechanic used a torque wrench, making clicking sounds. Then, the travel of the front and rear shock absorbers was checked, along with whether the steering ball joints had excessive play. The air conditioning evaporator was also removed for cleaning and disinfection. Finally, the diagnostic computer ran a full vehicle scan, even detecting fault codes in the window motors. After the service, the brake response felt noticeably sharper—definitely worth regular maintenance.

Last year's Service B at the dealership was quite comprehensive. First, the engine oil was changed using specific low-ash synthetic oil. After replacing the oil filter, they performed an engine deep cleaning. Both the air filter and cabin air filter were renewed – crucial for respiratory health. The chassis inspection used a lift, meticulously checking all linkage bushings for cracks. The brake inspection took the longest, with pad thickness measured three times for an average. All wheel bolts were retorqued to manual specifications. The electrical diagnosis was fascinating – plugging in the scanner displayed real-time voltage curves for each module on the large screen, with any anomalies highlighted in red. The entire process took about three hours, with no shortcuts taken on any safety items.
