'00 9-3 base model, 125,000 miles
That's funny... I posted here a few times trying to explain the noise, but nobody could help. I feel validated that you had it too.
Unfortunately, I don't know the problem.
Here's what I know... I had the startup whoooo noise just like you describe. I replaced the vacuum hoses... no help. I replaced the turbo bypass valve... no help. I cleaned the metal pipe connected to the banjo bolt on the turbo inlet.. no help.
All this time, you should note, that I had a turbo that was smoking on startup.
I finally took it in to get a new OEM turbo and they noticed that I had high crankcase pressure. They replaced the PCV kit with #6 (I already had #6 that I installed in 2008, so wow those things go quick). And they put in a new turbo.
The noise was immediately and totally gone. I just don't know which one did it.
Were I you, I'd replace the PCV kit with #6 because that's relatively inexpensive (remember the check valve too).
If that's not it, then based on my experience I'd say it's the turbo, but I just don't know where. My turbo shaft and bearings were fine, but the seals were gone. I don't know if that's relevant.
Best of luck.
