When changing the transmission fluid for a Volkswagen DSG wet dual-clutch transmission, manual oil change (gravity method) requires 4 to 6 liters, while using an oil change machine requires approximately 9 to 12 liters. The methods for changing transmission fluid are as follows: 1. Loosen the drain screw at the bottom of the transmission to drain the old fluid, then refill with new fluid. 2. Remove the transmission oil pan directly for draining and refilling: This method is more thorough than the first one, as it removes impurities accumulated at the bottom of the oil pan. 3. Use a circulation machine to change the automatic transmission fluid: A smart circulation machine performs a dynamic oil change, filtering and cleaning sludge and impurities inside the automatic transmission. Hazards of not changing transmission fluid for an extended period: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired transmission operation, leading to damage of the transmission valve body.

Should the Straight-going Vehicle Yield to the Turning Vehicle or Vice Versa?

Generally, turning vehicles should yield to straight-going vehicles. More information about yielding the right of way is as follows: 1. On auxiliary roads, straight-going vehicles should yield to vehicles merging from the main road. In China, main roads are often accompanied by multiple auxiliary roads to facilitate traffic flow. According to regulations, vehicles on auxiliary roads must yield to those on the main road. 2. Many intersections are marked with inverted triangle-shaped yield signs. When approaching such intersections, drivers must yield to other vehicles. 3. Right-turning vehicles must yield to normally straight-going vehicles. In China, right turns are generally not controlled by traffic lights, so right-turning vehicles must not interfere with the normal flow of straight-going traffic.

Why can't the Kia K4 start with one-key start?

Kia K4 one-key start not responding is usually caused by a dead smart key battery, insufficient battery voltage, or not shifting to the P/S gear when parking. Below are the relevant reasons for one-key start failure: 1. Dead smart key battery: This situation is most likely due to a dead smart key battery, causing the start system to fail to detect the weak signal from the smart key. It is recommended to place the smart key on the start button and then press the button to start. 2. Insufficient battery voltage, dead battery, or damage: Failure to start may be caused by a dead battery due to leaving headlights on for a long time or the battery reaching the end of its lifespan. Generally, replace the battery according to the maintenance manual. If the battery is dead, you can use another battery to jump-start or use the universal push-start method with a few people.

What does the TC light mean?

TC light stands for Traction Control System. When the TC light is on, it indicates that the Traction Control System is active. During vehicle acceleration, if the system detects a significant speed difference between the driving wheels and non-driving wheels, the computer will immediately determine that the driving force is excessive. It then sends a command signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the driving wheels. The working principle of TC involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal's information to the ECU, which generates a control voltage signal based on the received data. The servo motor then adjusts the throttle according to this signal, reducing the throttle opening and controlling wheel slip. For vehicle owners driving in rainy or snowy conditions, this system can help minimize occurrences of wheel slip or loss of control.
