Whirring noise

[LEGVR4]

Hi All,
I know its not much to go on but I have recently gotten a whirring noise from engine, whirring increases/decreases with revs.
Its easier to hear in the drivers seat rather than under the bonnet. Tried locating under bonnet and best I can narrow it down to is front of engine (pulleys/belts area).

Anyone had a similar noise. (see video).

Using my phone so hard to hear where i am... But

Louder when steering at full lock?

A/C on or off?

AC off, I tried steering a bit as well but not full lock.
Will give it a go, cheers

but good idea, i will take off Pow steer.AC belt and see if noise still there. Might help narrow it down a bit.

For those playing at home.. looks like its an idler pulley. Ordered a new one so hopefully will know for sure this weekend.
