Hey guys, wondering if i could get some help diagnosing a problem with my ML320 2002 (if there is any).

Here's a recording i took with my phone, the sound gets relatively loud halfway through the video. Sound is very evident at 0:40-0:46 :

(You'll be able to hear a whining in the background that gets louder the more you drive - loud at the end)

I've noticed there's quite a loud whiney noise after driving for roughly 5 minutes. This noise is very loud when stepping on the gas pedal as well driving around roundabouts.

I've also had a look at the engine belt and power steering fluid but they both seemed to be fine.

Am i being a bit paranoid? Or is there something potentially wrong?

Thanks!
