Engine Whine Noise?

Hi guys, recently i've noticed an intermittent kind of whine noise coming out of my engine. It's the 2.0 TSI, my car is a 2010. There isn't a lack of power when it happens, it just bothers me that there's a noise coming out of the car that I don't know about. I took a video, you can hear it next to the ticking, and a little more distinct when i turn the car off.


Listen, and let me know what it is if you have any idea! Thanks.

Sounds like darth vader..i would check for any codes and check for leaks if you have anything aftermarket.
