High pitch noise *VIDEO*

My 2015 X5 XDRIVE50I with 45k miles is making this high pitch noise. Does anyone know what this is?

The noise starts at the 0:20 mark.

Sounds like a worn belt.

Belt or pulley.

Agree with others as it sounds like it’s in time with the idle. Would like to know more detail like does the noise respond to throttle input, is it persistent after warm up cycle, does it stop at any point and only return when cold.

Most likely pully or belt tensioner
