Mercedes ML350 Power Steering

I recently purchase a used certified 2005 Mercedes ML350 and I started to notice that the power steering is making a whining sound every time I make a turn. I brought the car back to the dealer to have them check it out. The service advisor informed me that the whining is cause when your power steering fluid is low or leaking. After inspection, they stated that it was not leaking and they just added some fluids to the system. After two week, I still hear the whining sound. Any advice on what it could be?

FYI, Mercedes Dealer could not find the problem... so they replaced the rack & pinion and the Whining has stopped. Problem resolved. Thank god it was covered by my warranty!

Whining usually is power steering motor over work. Glad you got it sloved. My R350 has steering making click sound. Dealer also replaced some sort of steering parts, which I can't recall now. Problem solved.
