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

Simply double check your PS fluid----sounds like you have a leaky system!!

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.

If it's not the PS then the next check is the transmission fluid level, if that is not low than your torque converter is suspect---then it's big bucks!!
