Hello everyone , new here

My m3 makes a weird noise , I'm thinking it's the P/S pump going.
The sound is pretty much exact to this video :

If there is a previous thread to this issue - please send a link.
I know that I should probably take off the serpentine belt and start touching things and etc.
I do have some mechanical experience , I replaced timing chain guides on 03' 540i.

Any input will be greatly appreciated
