2018 E63s
This is comical. I dropped my car off this morning for this exact issue...it's a 2019! It's definitively valve related with sound emitting from the middle of the car and is not present when valves are closed. I made a video and sent it to my SA who wasn't able to discern the noise I described. I later got a call from the tech who had taken the car out for a drive and wasn't able to replicate the noise. I told him to take it out again, put it in S+ (valves open) and manual mode and to roll down the driver side window. Keep the car in 2nd or 3rd gears with hard revs to 5k and let the car decelerate to 2-3k and he'd hear it. I haven't heard back. Apparently he didn't roll the windows down (his words) on first drive. Seriously?

Scroll up and you should be able to see the video I uploaded and check if you have the same issue.
