Mein Auto: BMW X3 3.0D 1997
Question X3 3.0d rattle/whirring noise on cold start up

I have a3.0d 97 x3 and when cold near freezing or below a noise sounding like a whirring/rubbing noise can be heard coming in the general area of the alternator. After a few minutes and for the rest of the day the noise disappears! Has anyone any ideas as to what it maybe. Curious that once the engine is warm it cannot be reproduced.
