Need help identifying noise please

Hi all

I hope someone can help with a noise I’m getting I’ve attached a link below with the video.

The noise is more of a whine if that makes sense, the whine isn’t constant just when accelerating. More so at slower speeds…

It seems to happen when accelerating/ changing gear it’s a 2013 SD4 Auto, it also sounds like it’s comming front the front of the car / back of the engine ? drives fine and no error codes.

I’ve been told it could be the AC although the noise still happens but not as bad when it’s off, I’ve also been suggested it could be the power steering Resivour blocked ?

Thx in advance for any suggestions

It won’t seem to allot me to upload the video

You have to link to a video on YouTube.

I'm presuming it's a Freelander SD4?

Noise under boost is often a leak in a boost hose, or the turbo itself.

If it was the AC compressor, the noise would normally be there all the time, not just under acceleration.
Same for the PS, where the noise would be there all the time, and often getting worse when the steering is moved.
However it's important to replace the PS reservoir every 5 or so years, and do a fluid change with the correct green PS fluid.
