Do modern cars still require a break-in period?

Most new cars undergo cold break-in processes before leaving the factory, but they still require some running-in on the road. Here are specific methods for breaking in a new car: 1. Cold engine warm-up: Proper warm-up helps form an "oil film" between engine components to reduce wear. 2. Timely gear shifting: When driving manual transmission models during break-in, shift gears promptly and appropriately, avoiding incorrect behaviors like high gear with low RPM or low gear with high RPM, and don't use a single gear for extended periods. 3. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual - perform inspections and maintenance (including oil/filter changes and comprehensive chassis checks) upon reaching specified mileage or time intervals. 4. Avoid emergency braking: Emergency braking not only shocks the breaking-in brake system but also increases impact loads on the vehicle's chassis and engine.

How Many Kilometers Should a Three-Way Catalytic Converter Be Cleaned?

The three-way catalytic converter should be cleaned every 20,000 kilometers. The following situations also require cleaning the three-way catalytic converter: 1. When you notice increased fuel consumption and reduced power, check and clean the three-way catalytic converter as needed. 2. When performing maintenance such as cleaning the fuel injectors, throttle body, and intake tract, it is best to clean the three-way catalytic converter at the same time. 3. Before the annual vehicle inspection, it is advisable to clean the three-way catalytic converter to ensure passing the exhaust emission test smoothly. The effects of a clogged three-way catalytic converter are as follows: 1. The rear oxygen sensor sends a signal, causing the engine's fuel injectors to inject more fuel, and the engine warning signal indicates oxygen sensor poisoning. 2. Accompanied by a slight decrease in power and increased fuel consumption, the vehicle may fail the exhaust emission test during inspection. It can be removed, cleaned, and soaked on a lift.

What Causes the Abnormal Noise When a Volkswagen Turns?

The abnormal noise when a Volkswagen turns is mainly caused by the following reasons: 1. Excessive gear clearance in the Volkswagen's steering gear. In this case, the steering gear needs to be replaced. 2. The abnormal noise comes from the shock absorber's plane bearing. Applying some grease to the plane bearing can help. If the noise persists after greasing, the shock absorber's plane bearing must be replaced. 3. The abnormal noise is from the Volkswagen's stabilizer bar, caused by loose stabilizer bar bushings. This can be resolved by adding shims. If damaged, the bushings must be replaced.

How Often Should Mercedes-Benz Brake Pads Be Replaced?

Mercedes-Benz brake pads are not replaced based on mileage. Generally, they need to be replaced when the brake warning light comes on. Additionally, you should check the thickness of the brake pads; if it is below 3mm, replacement is usually necessary. Here are the methods for inspecting brake pads: 1. Check the thickness: A new brake pad is typically about 1.5cm thick. As it wears down through friction, the thickness gradually decreases. When the visible thickness of the brake pad is reduced to about 1/3 of its original thickness (approximately 0.5cm), the owner should increase the frequency of self-inspection and be prepared to replace it. Some models, due to wheel design, do not allow for visual inspection, and the tire must be removed to check. 2. Listen for sounds: If a metallic scraping or squealing noise is heard when lightly applying the brakes (this could also be due to initial break-in of newly installed brake pads), the brake pads must be replaced immediately. 3. Feel the pedal response: If you notice that the brake pedal feels harder to press and requires deeper application to achieve the usual braking effect, or if the pedal position feels noticeably lower during emergency braking, it may indicate that the brake pads have lost most of their friction and must be replaced.
