Question about 2004 Audi A6
Today it was -10 and its the first time the power stearing has made so much noise.
Check for leak in power steering hose by taking cap off the power steering resevoir and than starting car, wait 1 min, turn wheel all the way left and than all the way right. do this about 5-8 times slowly over 3 min or so. turn car off, than observe fluid in resevoir. if you see lots of bubbles after 30 seconds or so, you have a leaky hose. air in the system makes the steering pump groan and moan and vibrate. if the pump is not bad, than change the hose and clamp. just fixed mine yesterday. also buy a quart of 11s pentosin power steering fluid (green)...

Could be you need to flush the power steering unit if it hasn't been done for a while. Acting up when the cold hits is one of the symptoms.
