What do the two lights on the Passat's internal circulation mean?

The Passat has two lights for internal circulation. The left light indicates internal circulation, while the right light indicates automatic internal and external circulation, which means it will automatically switch between internal and external circulation based on air quality. External circulation uses a fan to draw outside air into the car, with the air passage between the outside and inside being open. The air blown by the fan comes from outside, and even if the fan is off, airflow is still drawn into the car while driving to replenish fresh air. The 2020 Passat features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 1.4L turbocharged engine, delivering a maximum horsepower of 150 PS, a maximum power of 110 kW, and a maximum torque of 250 Nm, paired with a 7-speed dual-clutch transmission.

What are the consequences of a broken car timing belt?

Here are the impacts of a broken car timing belt: 1. A broken timing belt will cause loss of power in the car. 2. Weak acceleration and unstable idle speed. 3. Abnormal noises from the engine. When the timing belt breaks, due to inertia, the crankshaft continues to drive the pistons up and down, while the valves remain stationary as the camshaft stops rotating. This results in bent valve stems and dented piston tops. In severe cases, the engine may require major repairs or even be completely scrapped. Additional information: Generally, vehicles need to replace the timing belt after driving 30,000 to 80,000 kilometers. If the timing belt shows signs of hardening, wear, fiber breakage, cracks, or fissures, it indicates that the belt is damaged and should no longer be used.
