Why does the Volkswagen Tiguan's fan keep running after the engine is turned off?
2 Answers
The fan continues to run for a long time after the engine is turned off because the turbo fan is cooling down the turbo. Here is some information about Volkswagen: 1. Introduction: Volkswagen AG is an automobile manufacturing company headquartered in Wolfsburg, Germany, founded by Ferdinand Porsche on March 28, 1937. 2. Brands: The company owns brands such as Audi and Volkswagen. In May 2021, Volkswagen Group ranked 17th in the "2021 Forbes Global 2000" list. 3. Development: On March 28, 2018, Volkswagen officially released the official images of the Atlas Cross Sport concept car, which made its global debut at the 2018 New York Auto Show. The car was also planned for mass production in the United States.
This is quite normal in the Volkswagen Tiguan, especially if you've just driven at high speeds or shut down the engine in hot weather. The fan will continue to run for a few minutes to cool the engine and prevent heat damage to components. However, if the fan runs for too long—more than 10 minutes without stopping—there might be an issue, such as a faulty coolant temperature sensor or insufficient coolant, causing the system to misjudge the temperature. Once, while helping a friend inspect their car, I found that the fan relay was stuck, and replacing it fixed the problem. I recommend observing the duration after shutdown next time. If it's abnormal, check the battery to avoid draining it completely or visit a repair shop to read the fault codes with a diagnostic tool. Regular maintenance of the cooling system is also crucial—replacing the coolant can prevent many unexpected issues. In short, don’t take it lightly—safety first. If the fan keeps running, it might affect the next startup.
