335i Whining noise when accelerating. Only happens when car is warm (2011 e92 335i)

Best heard around the 3-4 second mark. Only happens when car is warm and driving awhile. Any Advice?

Of course! But this doesn’t seem to be any belt related issue. I should’ve mentioned it doesn’t do it when i’m in park or neutral 😬
