I think it's egr valve open when cold and then it closes you are hearing that threw the intake normal.

If it is a 2023 it should still be under warranty. So I would have it checked by BMW. No reason not to take it in.

My car has the exact same noise on cold start up 8,000 miles I will do alitte more digging but really not concerned. Sounds like a pump of some sort is just priming if it's not egr valve.
