Just doing mine on my '11 535xi @ 2,100km (around 1,200 miles). There is no cover underneath for the drain bolt, and the shroud under the drain pan is silver aluminum compared to yours which is black plastic.
I guess this is some kind of skid plate?
I also noticed that the filter is tiny. It must be 1/3 the size of my previous 330ci.
Filling with 7 qts of German Castrol 0w-30.
