Dry and wet dual-clutch transmissions differ in the following aspects: 1. Cooling Methods: Dry dual-clutch transmissions rely on air cooling for heat dissipation; Wet dual-clutch transmissions are immersed in oil, offering higher cooling efficiency. 2. Operational Differences: Dry clutches use manual transmission friction plates, featuring high mechanical transmission efficiency but more complex operation and higher failure rates; Wet clutches employ automatic transmission oil-immersed friction plates, with lower mechanical transmission efficiency but easier operation and lower failure rates. Dual-clutch transmissions are not suitable for frequent starts, prolonged low-speed driving, or stop-and-go traffic conditions, as they are prone to overheating, which can lead to malfunctions. Once the vehicle's computer issues a warning, it is essential to stop immediately to cool down the transmission.

What does crulse mean on a car?

There is no crulse on a car, but there is cruise, which refers to the cruise control system. Cruise control, also known as speed control system or autonomous driving system, functions by maintaining the vehicle speed as set by the driver without the need to press the accelerator pedal, allowing the car to travel at a constant speed. The working principle of the cruise control system is as follows: the cruise control unit reads the pulse signal from the vehicle speed sensor and compares it with the set speed, then issues commands to the servo mechanism to adjust the throttle opening, either increasing or decreasing it, to ensure the vehicle maintains the preset speed. In addition to the function of canceling via the brake pedal, cruise control also has cancellation functions through the parking brake, clutch, and speed adjustment lever operation switches.

What causes the EPC warning light to illuminate in a Tiguan while driving?

For the Volkswagen Tiguan, the illumination of the EPC warning light can be attributed to the following reasons: 1. Issues with the vehicle's computer system. 2. Possible contamination of the engine's throttle body. 3. Leaks in the intake system, prompting the engine control unit to detect the problem and activate the EPC warning light. 4. A continuously lit EPC warning light indicates a malfunction in the engine management system or electronic control, often accompanied by unstable idling or engine shaking during cold starts. However, for domestic vehicle owners, this is usually caused by the quality of fuel and a dirty driving environment. It is recommended to drive to a service station for inspection as soon as possible. In most cases, cleaning the throttle body can resolve the issue. 5. The EPC indicator light will illuminate during a functional check when the ignition is turned on. If this light comes on while driving, it indicates a fault in the engine's electronic power control system.
