I was at the dealership with this "leaking" air rattle problem while under throttle, it's best heard in 3rd and 4th gear at low RPMs. I wanted them to check the solution that user "burns all" suggested on another board, asked them to check "Loose pipe clip on induction system". They checked and said there was nothing wrong with it, but...
They said that there's a new campaign that popped up in their system and it's exactly about the induction system. He said that BMW admitted some unintended, factory-made holes in the air induction system which they recommend now to be closed with a special tool which they ordered.
BMW also mentioned that this defect not only can cause the rattle air sound that I noticed long ago, but can also cause a negative impact on car's air induction. Check your dealerships about this guys.
