My guess is that you didn't remove the lower bolt, to flush the engine from the coolant, and the crap was there too....

Remove the bolt (as discribed in the website) and flush again. Run water until it runs clear. Then put the bolt back, run water until it runs clear out of the radiator. Remove the bolt, drain everything. Put the 2 bolts back the fill it up with BMW coolant and distilled water (50%-50%).
Bleed, bleed, bleed.

And voila!
