A charge pressure test will confirm, your local indie or dealer should be able to do this and tell you the result inside 1/2 hour

My Turbo whistled had a bit/lot of black smoke the fix was a £3.20 O-ring from MB on the inlet side of my Turbo.

It is quite common for turbos to whistle when cold. Usually goes away when hot. I found that using heavier engine oil (15/40) made the whistling worse. Mine has been doing it for years with no issues.
