Whining/moaning noise after sharp turning

I have a 2010 e92 with 80k miles and last week when driving aggressively the car would make a high pitch moaning/whining noise.

Now this noise happens all the time if I make a sharp turn. It's a moaning and humming noise and if you leave the car off for a few minutes it goes away but comes right back after a sharp turn or curve.

Any ideas

Immediate thought is power steering pump issues. It could be as simple as the fluid being low, or incorrect/contaminated fluid causing foaming.

I appreciate the reply now that I think about it the sound is nearly identical to when my 335 was low on PS fluid.

I will top that off later this afternoon and report back

I remember this being my differential fluid.... once they changed it my car was perfect again...
