Power Steering Whining with video! HELP

I have a 2006 cls500, lately my car is making a whining noise and its getting louder. I have read about changing the reservoir and the power steering pump, the noise is still there. The car still drives the same, noise does not change when I turn the wheel. Only gets louder when the rpm goes up. Has anybody had this problem.

Here is the sound, I uploaded it to you tube.

Are you sure the noise is from the steering?? They also have a problem with the idler pulley and also the a/c clutch on the a/c compressor. Locate the idler pulley and hold a screwdriver in the back of it (be careful of the belt)---you can hear locate it that way or a better way is the install a bypass belt that bypasses the a/c compressor. if the noise goes away obviously its the a/c clutch. if its still there its the idler pulley**idler pullies very common*************
