I’ve been hearing this rattle/knock noise as well. Only on a cold engine, and goes away completely once warmed. Some cold tolerances or something, who knows. BMW does like to plague their best engines with rod bearing issues though

My car is just over 1200 miles, and it’s been doing it since new, and even after the break in oil change.
