Volkswagen Beetle cooling fan stays on after engine shut off requiring battery disconnection on Volkswagen Beetle

Some Volkswagen Beetle owners report experiencing issues with the cooling fan continuing to run after the engine is shut off, indicating potential problems within the vehicle's system. This persistent fan operation may be caused by a dirty radiator, which can impede proper cooling. Additionally, a faulty electronic control unit (ECU) or defective temperature sensors could lead to the fan running continuously. Some owners have also identified a bad fan relay as a possible culprit for this issue. Electrical wiring problems, such as a short circuit to mass wires, may further exacerbate the situation, while faulty freon pressure can also contribute to the fan's abnormal behavior. It is crucial for owners experiencing this issue to address it promptly to prevent potential damage to the vehicle.
