Bestune B70 reverse light not working reasons: bulb damage, power circuit break, professional inspection is required. Bulb damage: First, check the bulb. If the bulb is damaged, it needs to be replaced; then check the wiring to see if it is caused by a short circuit; finally, check if the fuse wire is broken. If it is, it needs to be replaced at a repair shop. Power circuit break: Check if there is power at the relay live wire terminal. If there is no power, check if there is a circuit break between the wire and the power source; if there is power, use a screwdriver to connect the two terminals of the relay. If the reverse light turns on, it indicates a relay failure and it should be replaced.

Why Does the Steering Wheel Feel Stiff When Driving at High Speeds?

Car steering wheel stiffness at high speeds can be attributed to: 1. If the steering wheel feels slightly stiff when driving at high speeds, especially in hydraulic power steering models, the issue is likely related to the power steering fluid. Dirty power steering fluid or air in the system can cause this phenomenon; 2. Slight stiffness in the steering wheel could also be due to a binding steering column or an unresponsive steering angle sensor; 3. If the steering angle sensor is not properly lubricated, it may stick, leading to slight stiffness in the steering wheel. Solutions for steering wheel stiffness: Some minor stiffness issues can be resolved by adjusting the steering wheel up and down and then returning it to its original position; others may require turning the steering wheel lock-to-lock a few times while stationary to eliminate the stiffness.

How many kilometers should the Magotan fuel filter be replaced?

Magotan's fuel filter should be replaced every 40,000 kilometers. Long-term failure to replace it will result in: reduced filtration capacity of the filter element, clogging of the fuel filter, which will affect fuel pressure, leading to insufficient fuel supply, allowing some impurities in the fuel to enter the fuel injector, valve, and cylinder, thereby affecting the normal operation of the engine. If high-quality gasoline is used, the service life of the fuel filter will be longer. Magotan is FAW-Volkswagen's first B-segment sedan, with dimensions of 4866mm in length, 1832mm in width, and 1464mm in height, and a wheelbase of 2812mm. The vehicle is equipped with an ESP electronic stability program, which can effectively prevent the car from skidding when avoiding obstacles at high speeds, ensuring the safety of the driver and the vehicle.

At what level of tire aging must replacement be done?

Tires must be replaced when they develop numerous fine cracks or when the tread wear indicator reaches a height of 1.6 millimeters, as continued driving under such conditions poses safety risks. The fine cracks on tires are commonly referred to as tire cracking. The presence of cracking not only affects the comfort level of the tire but also significantly reduces its grip performance. When such cracks appear, the tire should be replaced promptly. Generally, every car tire is equipped with a tread wear indicator, with a standard height of 2.4 millimeters. The minimum tread wear indicator height is 1.6 millimeters, and when the wear reaches this level, it indicates that the tire should be replaced immediately.
