Find out under what circumstances the noise can definitely be provoked reliably. Maybe even put a video or at least a sound recording on Youtube and link it here. And share at least the most basic information about the car.

Is it a car with turbocharger?

If so, it could be that the charging circuit is leaky and thus the turbocharger causes a whistling noise under load.

It’s just a guess!

Well, then that’s cleared and cut off.

Open the hood and try to locate the pipe closer. Could also be the lighting machine

Maybe just wind sounds?

Remote diagnosis is not possible, let it be checked in the workshop.

Could come from the turbocharger if there is.

I used to slip the air intake hose off the engine. Also caused a whistle at higher speed.

Maybe the V-belt has to be stretched or replaced.The one could slip and cause the noise.

Clear air hose at the intake tract.
