Why does the Volkswagen Tiguan hood open by itself?

[MacKylie]

The front cable is pulled too tight, causing it to pop open automatically. Here are the specific details: 1. Cable issue: The hood is opened purely by a physical mechanism without any electronic components, so there are no sensor malfunctions involved. After ruling out and replacing the latch, it can be basically confirmed as a cable issue. The solution is simple: replace the hood cable. If the replacement isn't done properly outside, it's best to have it repaired at a 4S shop. 2. Function of the car hood: Airflow guidance: For objects moving at high speeds through air, the aerodynamic drag and turbulence generated around the moving object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resulting resistance, reducing the impact of airflow on the vehicle. Protection for the engine and surrounding pipeline components: Under the hood lie crucial components of the car, including the engine, electrical circuits, fuel lines, braking system, and transmission system, among others.
