If you have a BMW that is making an engine noise that you haven't ever heard, there is a good chance the valve cover (cylinder head cover) needs to be replaced. There is an issue where the crankcase ventilation reservoir integral to the valve cover fails and the sound is beyond belief.
Listen to the video. If you hear something similar, check if the sound is coming from the valve cover area.
