Reasons for a car display screen not lighting up: Central Control System Defects: Some brands and models of mobile phone Bluetooth or third-party software may be incompatible with the host software, causing the central control screen to go black when connecting or playing songs. In this case, the central control system usually returns to normal after a restart. Issues with the USB Port in the Central Armrest: Plugging something into the USB port in the central armrest can cause the screen to go black. The solution is simple: just unplug the USB device. Power Circuit Fault: If the issue is caused by a power circuit fault, you can only go to a 4S shop for inspection and repair, as circuit faults cannot be handled on your own.

Is the Volkswagen Tharu engine dry or wet type?

Volkswagen Tharu is equipped with two types of engines: a 1.4T and a 2.0T. The 1.4T engine is paired with a 7-speed dry dual-clutch transmission (code-named DQ200), while the 2.0T engine is matched with a 7-speed wet dual-clutch transmission (code-named DQ381). Below is a detailed introduction to the Volkswagen Tharu engine: 1. Dual-clutch transmissions are widely used in the Volkswagen brand and are currently the most popular type of transmission. This engine is not significantly different from conventional engines, except for the addition of an extra set of clutches. The biggest advantage of dual-clutch transmissions is their fast gear-shifting speed, providing smooth upshifts, ample power, and excellent fuel economy. 2. Volkswagen models with the common 1.4T engine mostly use dry dual-clutch transmissions, while models with the 2.0T engine generally employ wet dual-clutch transmissions. 3. During engine operation, the dual-clutch transmission generates heat through friction, especially in urban or congested traffic conditions. Dry dual-clutch transmissions are more prone to overheating because they rely on air cooling, which is relatively slow. In contrast, wet dual-clutch transmissions use oil immersion for cooling, resulting in faster heat dissipation compared to dry dual-clutch transmissions.
