The turbo is unbalanced ....
My advice is take it out and have it fixed while you can or else it will break :p

That whistle is produce by the the unbalance that occurs with natural worn of the repair kit inside the turbo...

Its pretty natural to happen

i wouldn't worry about it, if the power is still there and its boosts fine then the turbo is fine, mines whistle quite loud when its cold as do many of the others on here, a alot of the newer common rail diesels have the turbo whistle just to do with the high turbo pressures that they run, but once warmed up you can't hear it at all, and only if you put the windows down will you hear the induction whoosh of the turbo sucking in the ait through the intake, some like the sound some hate, me personally i love it.

Mine whistles quite loudly, and VXR Mike's old 1.9 had the same whistle at about the same volume. It's always done it and when it was standard, it still ran 155BHP on the rollers.

I'd say it's fine, but might be worth doing a sound recording and seeing if we're thinking of the same noise? :)

oh yeah should have added mines has done it since i bought it and has covered 16k miles since then and hasn't blown up yet, just a natural thing, but as mike's said get a vid up, we may be confusing the whistle with something else :)

Can you take out the inducer pipe that goes from the maf to the compressor housing ?
And check out the turbo is ??
You have to balance it up and down and front and back.

Lol well I ment I don't have this sound on mine 1.9, sounds nice, like the wistle, but I prefer to not have this sound on my car. Maybe my car is a low miliage car, but yes a whistle doesn't mean anything.

Well it does get you noticed going passed the cars cruising around town but it can get annoying over time so the speakers then get tested out to drown it out abit. I think it would be one of them things you missed if it disappeared tho.
