How to Fix the Automatic Pop-up of the Tiguan Front Hood?

[DeJosephine]

The automatic pop-up of the Tiguan front hood is caused by engine overheating. The solutions are as follows: 1. Add coolant: Prolonged water circulation during engine operation can gradually deplete the coolant in the engine cooling system, leading to insufficient water in the radiator. If not checked and refilled in time, this can easily cause engine overheating, resulting in the hood automatically popping open. 2. Check if the cooling fan is faulty: Damage to the cooling fan or a short circuit in the wiring can cause the fan to malfunction or operate at a slow speed, preventing the engine's heat from dissipating. This will naturally raise the engine temperature, causing the hood to pop open automatically. 3. Check if the thermostat is faulty: The thermostat controls the flow path of the coolant. If it becomes stuck or fails, the engine's large and small circulation will inevitably be affected, preventing the engine's heat from being effectively dissipated.
