That's not a maf. Thats a manifold pressure sensor and if you have an N54 then there isn't a Maf on the car. Plus oil in the intake is completely normal on all BMW engines. I've never seen a single one that wasn't at least coated in a thin coat. It's how the crankcase ventilation on these cars is. Totally normal.
