Hey,

Just wanted to ask if anyone knew why my car is idling very weird whenever I turn on the fans inside the cabin. I would understand if the rpm’s went up when I turn the a/c on but the idle just keeps fluctuating. I have a 2017 bmw 440i and it’s also around 92k miles if that matters. I provided a video below so that you can hear what I am experiencing. Any suggestions would be much appreciated.

If nothing looks obvious, I would try pulling codes. If you don't have a method to check, you should. Some inexpensive options are the BimmerLink app with a OBD scan tool like Veepeak or an inexpensive scanner from the Creator line that will work with your car. Available on Amazon.
