Thinking low power steering fluid? Nah, I don't think so, in fact,
I know it's not that. Turning the wheel doesn't make any difference.
I think this sound may be related to a similar, but slightly different
sound I get on cold mornings when I'm driving down the road
before the car warms up.
If it's actually a bearing, it will usually be worse if the wheel is
turned to the side, as it will put more lateral force on the bearing.
Also, it could be something loose scraping against the tire slightly,
but that again would change depending on the position of the wheel.
Could even be control arm bushings. But you'll know if you put it up
and turn the wheel by hand.

I've the same problem on my 01 e39. It's there when you only pull off and
dissappears after 50 yards.
Does yours only happen then the car is moving in gear? If you depress the
clutch is it still there? My thinking was perhaps the cluth bearing, car is
in next week so will know more then.
I've changed my front upper/lower arms but hadn't thought about a sticking
caliper - could be.
let us know how you get on.
