Squealing noise but unable to identify!

Okay, so I have this weird, intermittent squealing noise coming from the front passenger side of the car. It is mostly evident when car is cold and either standing still or at low speeds. It is more evident when turning the steering wheel to the right slightly and quietens when straightening up or turning left.
It disappears after a few miles when the car is warm.

I personally think it could be a wheel bearing but have my doubts as shouldn't it be evident constantly for it to be a bearing? I initially thought it sounded like it was coming through the glovebox but I can't seem to find anything there.

Any ideas?

EDIT: I have now made a video of it. Once I'm on a PC I will upload.

If the car is standing still it won't be a wheel bearing.

At first I thought the power steering motor if you have EPS

Ahh okay fair enough. Think it is hydraulic power steering? Do you think it could just be the fluid needing changing or maybe the pump?

Link to video which highlights the noise:

sounds like your blower. http://www.e90post.com/forums/showthread.php?t=542618

I did mine a few years ago now and not heard a thing since.

Wow seems easy! Will give it a go! But what is the explanation for the sound changing with the steering?

I don't know why the noise changes but mine would only make the noise whilst braking. Worth a shot
