I'll check it out when I get back home tonight.

Do the fans cycle when the engine is first started?

On my old A4 I got a funky noise at startup for a while. The noise only
lasted a few seconds tho - I'd say less than 5.  Waited long enough and it
turned out to be low power steering fluid.  I'm guessing the pump was
churning air and fluid but ???  Worth a look....

When I start my car after it's been sitting for a while (morning or after
work) it makes a high pitched whirring/grinding sound from the left side of
the engine for about a minute, after that it stops. It runs and drives fine.
If I rev the motor while it's making this sound, the tone does not change at
all, it stays constant. Because it stays constant I don't think it's turbo
related. 

Any ideas what this may be?
