I've got good news and bad news...

I have the same whistle in my 1M at exactly 2K (and a bit higher). It goes away once the car is warmed up. I do like the sound -but agree, it would be bad in the X5/X6. 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?
