Does anyone have any idea what this noise could be?
The whistling noise apear when i drive and i press the gass peddal over 1500-1800r/min. If I park and the car is not in drive, the noise does not appear even if I press the gas pedal, the noise only appears while driving. Bmw X1 F48 Xdrive 2.0D 2017.

It could be a boost leak or a problem with the turbo.

Make sure the rubber gasket in the engine bay is installed on the partition that divides the engine bay from the cowl/windscreen. I left this out one time and it made the turbo whine very audible in the cabin.

Do you have a roof rack? BMW roof racks that have air deflector pieces can make the most annoying whistling sounds. Happened on my e90 before.
