I dont think the E91 got the N52B30 engine. It will either be N52B25 or N53B30.

The diagrams visually look identical. Is there a way to find out which do I have?
I have been drilling inlet manifold swap forums for past 3 hours and thought that visually they 3 stage is different to 1 stage but now I am getting confused.
