Problem with the 2007 Mercedes-Benz Mercedes Benz Gl 450

My 2007 Gl450 ...when it is cold weather and i start it, it sounds really loud, kind of whining in the engine. It takes until it is really warmed up to stop. It is loud enough that you can hear it from inside too, but super loud from the outside. What could it be?

Not uncommon...... my 07 and other vehicles I have owned , have done that in really colld temperatures. Usually it is the power steering pump that causes that sound..... any kind of hydraulic pump will most likely sound like that when temps are well below freezing.

You could be a little low on power steering fluid. Mine really howls in cold weather if it is low.
