Is the exhaust pipe of Volkswagen Golf blowing normally?

Normal. There is a set of heat removal fans in front of the vehicle water tank. When the water temperature in the exhaust pipe of Volkswagen Golf Water Tank reaches a certain temperature, it will automatically rotate to help the water tank dissipate heat. Although the car is turned off, sometimes the water temperature in the water tank is still high, and the exhaust fan will naturally not stop. As long as the water temperature drops, the fan will naturally not blow.
