Why does my car make a fan noise when I turn it off?
Engine cooling fans and other systems are programmed to keep running in some cars even when the engine is off. And many other sounds from under the hood of a car that has been shut off are also normal.
Why is my engine making noise after I turn it off?
The “pinging” noise you hear is coming from the hot metal cooling under your car. As you drive, the engine and all the parts around it start to heat up and expand. Once you turn the car off, those metals will cool and contract. These tiny bumps produce the “pang” or “ping” you hear coming from your turned-off car.
Why does my VW make a loud fan noise?
Could just be the radiator fans running if you have been in slow traffic and the engine is really hot. 40 mins possibly but wouldn’t have thought it would need cooling after only ten minutes driving. Have a look at the oil temperature which is a better indication of engine temperature. It’s the DPF regeneration.
What makes a loud fan noise after switching off?
It’s not just after switching off – you’ll notice it sometimes happens when driving as the idle revs are at about 1100rpm. (Definitely not 3 zone a/c related as I don’t have that).
Is it OK to leave the cooling fan on when the engine is turned off?
Car Fan Still On When Engine is Turned Off You park your car, turn off the ignition and start walking away. Then you notice the engine cooling fan is still running even though the car is turned off. It is ok for the engine cooling fan to keep running for a few minutes after turning off the car.
What should I do if my car fan makes a loud noise?
It should be noted that the amount of soot allowed in the canister is carefully monitored, and if multiple regens fail, a warning light may come on the dash, and in severe cases a workshop visit may be required so that they can instigate an active regen using their workshop diagnostic equipment (which is chargeable BTW – not under warranty).
