High speed noise

[Albion]

Hi everyone,
I wanted to discuss a problem that i think its not good about my BMW 730d xdrive (G11) the year of the car is 2021.
My issue is that one day i drove it at the high speed and when it reached the 250kmh an unusually sound started at the passenger side it looked that it came from the klime but I tried even turning the climet control off i heard the same noises did anyone has the same problem and what was the solution for it.
Thank you!!

Got to wonder how many owners have even taken their car all the way up to 250km/h.

I’ve done that and beyond, but no funny noises on mine.

Mine has had to have door seal replaced on body side. Also the rain strip/gutter on passenger side came loose near rear windshield. Both caused a whistle type noise. Good luck. A frequency measurement app can help find the noise.

Is it just occurring at or near 250kph?

The only funny noise I hear is the passengers yelling at me, telling me to slow down.

Check nearside low door seals. Or if air gets under the bonnet into the airbox (poller filter area).
One of my friends had this on his 730. He found leaves and dirt in the area , guess they fly around.
