Whining/buzzing when turning steering wheel
I have a 2003 C32 and when I start the car in the morning when it is cold and then start driving, when I turn the steering wheel left or right there is an unusually loud whining/buzzing noise. The noise usually goes away after the car warms up. Anybody experience this? I am thinking there is something wrong with the power steering? I have had this car for only a couple weeks, so not sure what is normal with these cars....

i had the exact same problem. loud whining/buzzing from front when cold start. after starting the car when it's warm, or in warm weather, it was gone. the power steering fluid needed to be topped off in my case, it was too low.

My steering wheel does the same thing. I was doing doughnuts and my power steering died on me. The dealer replaced the power steering pump and rack & pinion. I got the power steering back, but when driving at slow speeds (5mph and under) the wheel makes this annoying grinding noise and the steering feels very heavy. I took it back to another dealer and they made it better, but its still there.
