2011 C300 Low Rpm whining noise

Hello everyone

Recently I've noticed in parking lots and going no more than 10 mph a whining noise coming from my car when I accelerate slowly. I also hear it whine when I get up to around 1,500 rpm it comes back but goes away when I let off the accelerator Also having problems with my power steering its making weird noises when I turn my steering wheel i dont know if its the same problem possibly
Would anyone happen to know what this might be would appreciate the help or some comments
thanks

I have the same experience and also am curious if anyone knows. I thought it might be the turbo but under such low throttle, I doubt it. I have no power steering issues.
