2008 E92 M3 Whining noise (Idler Pulley)

Hello all, I recently experienced a very high pitched and loud whining noise on my 08 M3. A lot of people were telling me it sounded like power steering but it ended up being the idler pulley. Just posting in case this will be of any help to anyone in the future.

( Just uploaded because it sounds sick)

And if anyone has a used SC kit let me know lol

I would do pulley first and see if that fixes it. It's a $60 part.

Belt whining/squeaking are also common but gotta change the belt soon. I broke mine thinking it's common thing. Mine also was stopped after a weak or so and got broken after couple months without any noise making.
