Bimmer876 is on a distinguished road
I have a 2007 X3 and I had a similar noise like that, I changed all my belt pulleys, oil filters and still the same. Until about a week ago I decided to do a transmission fluid change. Noise is all gone and she's BMW quiet. I believe the fluid level was incorrect as it passes through the transmission oil cooler.
