If you discover oil leakage from the rear axle differential, simply visit a 4S dealership for replacement. Differential: The automotive differential is a mechanism that enables left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right half-shaft gears, two planetary gears, and a gear carrier. Function of the differential: When a car turns, the turning radius of the inner wheel differs from that of the outer wheel, with the outer wheel's turning radius being larger than the inner wheel's. This requires the outer wheel to rotate faster than the inner wheel during a turn. The differential's function is to meet this requirement of different wheel speeds during vehicle cornering.

Can a motor vehicle make a U-turn by entering the left lane?

Driving a motor vehicle can make a U-turn at locations without no U-turn or no left-turn signs or markings, but it must not obstruct the normal passage of other vehicles and pedestrians. Precautions for driving a motor vehicle: 1. Road division: Based on road conditions and traffic needs, roads are divided into motor vehicle lanes, non-motor vehicle lanes, and pedestrian lanes, with motor vehicles, non-motor vehicles, and pedestrians traveling in their respective lanes. On roads without designated motor vehicle lanes, non-motor vehicle lanes, and pedestrian lanes, motor vehicles should travel in the middle of the road, while non-motor vehicles and pedestrians should travel on both sides of the road. 2. Obey traffic commands: Vehicles and pedestrians should follow traffic signals; when traffic police are directing on-site, they should follow the instructions of the traffic police; on roads without traffic signals, they should proceed under the principle of ensuring safety and smooth traffic.

How to Turn on Car Fog Lights?

Car fog lights can be turned on using the following methods: 1. Rotate to turn on fog lights. Some vehicles have fog light controls on the light lever, which are activated by rotation. When the button marked with the fog light symbol in the middle is turned to the ON position, the front fog lights will turn on. Then, turning the button downward to the rear fog light position will activate both front and rear fog lights simultaneously. 2. Button to turn on fog lights. Some vehicles use buttons to activate front and rear fog lights. Near the dashboard, there are buttons marked with fog light symbols. After turning on the lights, pressing the front fog light button will illuminate the front fog lights; pressing the rear fog light button will illuminate the rear fog lights.

Will points be deducted for deviation during gear shifting?

No points will be deducted if the vehicle does not cross the line. During the Subject 3 driving test, generally no points are deducted as long as the vehicle body doesn't cross the line. Solutions for frequent deviation during gear shifting in Subject 3 include: 1. Don't move the steering wheel; Holding the steering wheel too tightly. Relax a bit, if you don't move the steering wheel, the car will move straight forward without swaying left or right. 2. Pay attention to gear shifting; The left-right swaying occurs because your left hand grips the steering wheel too tightly, and when your right hand shifts gears, it unintentionally pulls the steering wheel. 3. Hold the steering wheel lightly with your left hand; You can also try holding the steering wheel lightly with your left hand while performing gear shifting operations.

How many years can a BMW 3 Series generally last?

With regular maintenance, a BMW 3 Series can generally last for more than 10 years. Here are some maintenance considerations: 1. Regularly clean the filters: It is important to frequently clean the car's filters, as this directly affects fuel consumption. During the operation of the car's internal combustion engine, dust and other impurities will continuously mix into the engine oil. Additionally, the oxidation of the oil by air and combustion exhaust gases will gradually form sludge or deposits, which not only accelerates component wear but can also cause blockages in the oil passages. Therefore, it is necessary to regularly clean the car's filters until it's time to replace the air filter. 2. Adjust tire pressure: Low tire pressure can lead to abnormal wear or internal damage to the tires, while high tire pressure makes the tires and rims more susceptible to deformation from impacts on uneven road surfaces and may even cause a blowout. Tire pressure must be checked regularly. Apart from the spare tire, the other tires should be checked at least once every two weeks. The tire pressure check must be performed when the tires are cool, as high temperatures can increase tire pressure, leading to inaccurate readings.

What Maintenance Does a Six-Year-Old Car Need?

Here are the methods to deal with fogging on the outside of the car's front windshield: 1. When there are water droplets on the outside glass. Adjust the air conditioning temperature slightly higher, direct the vents away from the windshield, and use the windshield washer and wipers to promptly resolve the issue of water droplets forming outside. 2. When fogging occurs inside the car. If this happens during summer after rain, immediately turn on the air conditioning in cooling mode and adjust it to blow air onto the front windshield to quickly disperse the fog on the glass. If fogging occurs inside the car during winter when temperatures are generally lower and the air conditioning cooling effect is slower, it's best to open the windows immediately to resolve the fogging more quickly. Using the air conditioning heating method can also remove fog, but this method is slower and may cause more fogging on the side windows, affecting driving safety, so it's not recommended. Additional information: 1. When the inside temperature is low and the outside temperature is high, you may notice water droplets forming on the outside glass surface where the air conditioning air hits. This is due to moisture in the air condensing into water droplets when it meets cold surfaces, similar to how condensation forms on air conditioning units. 2. When it's cold outside and warm inside, fogging occurs very quickly, which is the most dreaded situation while driving. This is also caused by moisture in the car's air condensing into tiny water droplets on the cold glass.

Early Signs of Transmission Failure in the Excelle GT?

Early signs of transmission failure in the Excelle GT are as follows: 1. Transmission oil leakage: You may noticeably feel difficulty when starting the car, and although the engine RPM increases when accelerating, there is no obvious sense of speed improvement. The culprit could be oil leakage. Oil leakage leads to insufficient lubrication inside the transmission, causing it to malfunction. This issue is relatively simple to fix—just replace the transmission oil. 2. Transmission jerking: Symptoms include noticeable jerking or shaking during gear shifts while driving. The cause may be excessively high transmission oil temperature, stubborn dirt and impurities inside, or blockage in the valve body, leading to transmission jerking. Please visit a 4S shop or repair shop for inspection and maintenance. 3. Engine stalling after shifting gears: When shifting from P to D gear, the engine may stall immediately. The source of the problem could be damage to the solenoid valve or lock control valve, or a faulty input shaft speed sensor. Stop the car immediately and contact a 4S shop or authorized repair shop.
