Why does the fan keep running after the Tiguan is turned off?
1 Answers
Tiguan's fan continues to run for a long time after the engine is turned off because the turbo fan is cooling down the turbo. When driving, it's important to note that you should not turn off the engine immediately after reaching your destination. Since the turbo operates at high speeds during operation, the temperature of the turbocharger in turbocharged models becomes very high after working. Avoid turning off the engine immediately to prevent damage to the turbo and shorten its lifespan. Here are the specific details: 1. Normal phenomenon: During operation, the temperature distribution in the entire water circuit is not uniform, with localized high-temperature points. When the water pump stops working, these heat spots cannot be dissipated, so the fan delays shutting off to facilitate cooling. This is a normal phenomenon and not a malfunction. 2. Automatic shut-off: Even though the car is turned off, the temperature hasn't dropped yet. The electric fan is controlled by sensors. Sometimes, during summer, if the car is parked under the sun, the electric fan may run even without driving, as long as the temperature reaches a certain level. This situation is entirely normal. If you don't want the fan to run, you can turn the ignition switch back on after turning off the engine, but do not start the car—just power on the system. At this point, the electric fan will automatically shut off.
