Have you checked the diverter valve for tears as this will do the same through the revs. Mine was like it for ages then changed the DV and all fine

I replaced my whining turbo at 55k thinking it was dying, seemed ok on removal.

Replacement (brand new at time) is doing the same after 16k. Even though I always let oil circulate before revving, engine get up to temp before driving full pelt, and let it idle for a good few seconds before switching off.

My wife's Altea also whistles faintly, as does the 6 month old A1 car I have at minute.

I know there are tonnes of bad stories but I'm starting to believe it's a trait of VAG turbo's.

If you're worried, keep on top of oil changes and have a good garage check out  the turbo and your hoses (for leaks).

Yea well I don't rev it when it's cold. And don't do much before its up to temp. When I turn on engine I let it turn over for min or so before I drive. And don't turn it straight off. I'll get it in have a good service see what comes I think. Thanks
