Help - WHINING Noise at start up (COLD) - The Unofficial BMW M5 Messageboard (m5board.com)

Hey Everyone,
HOPE SOMEONE can help!!
At start up in the morning, I have a loud WHINING noise in the engine.
Can also feel the whine through vibration in the steering wheel.
After about 10 - 15 minutes of slow driving, it seems to subside and go away.
NO dashboard errors - has the usual rough noises (cold or warm from new) but this is supposed to be normal.
THIS HIGH PITCHED WHINE is obviously NOT!!
Can anyone HELP???
Do not want to take to the dealer quite yet, as when I do, it will be time to put the beast to bed for the winter!!!

Want to get at least a week or two more - is this something that I should be worrying about?

(ONLY 32,012 KM.) - 2006

Thanks in advance for everyone that can help me out!!

Could possibly be a loud Vanos or your High Pressure Oil Pump.

maybe a belt is overworn?

My 2008 M5 has done the same thing. Its your power steering pump binding / freezing up. It's a known issue and covered under the 50k warranty. My pump and serpetine belt has been repalced twice within the 35k miles. I'm the original owner. Dealer can complete the work in a day.

Is the whining rhythmic almost like breathing ? I have something like this and it subsides as well. I am not sure what it is.
