Since we have a different turbo setup, I suspect that it is not the wastegates (plus I would expect that noise under load if it was them). So I suspect it is something with the air intake. Does your sound go away after it is warmed up?
Hello Doug, thanks for the advise.

The dealers had replaced the wastegate. They initially thought that was the problem too. That didn't fix the problem.

The sound occurs consistently, regardless of the engine temperature.
Even if I drive for over an hour, the whistle still occurs.

The noise is more noticeable when starting from a complete stop in D gear (or M2).

I do like the sound of turbo - but only like those constant air-sucking sound when sports car accelerates.
This one sounds broken to me..
