Really I don't think that'll be necessary. The 35i does it and so do the 35d and 30d. I've had other BMW turbos that do this as well. It's not a problem with YOUR X3 or any X3 at all. It's really just the turbo spooling under hard acceleration.

If it is that's sort of ok. It's not a pleasant sound though. My 335i certainly did not do it, nor did other petrol turbos from 80 and 90's which are older tech. My 335i must have been similar to the X3 35i - no unpleasant sounds, apart from at idle. With a passenger in the car it's kind of embarrassing, ie what sort of crap is this?

Mine does NOT make noises full stop. I had the X6 35D and the 635D Sport, they made no noises either, thats 3 new BMW Diesels. None of which made undue hissing or turbo wining ever.

BTW, the noise now seems to have gone. It only happened the first few times I totally floored it, maybe it was transmission related but whatever, it's now gone as far as I can tell. Trying to make it happen has left me with a consumption reading on 23 mpg.

I've only been doing short trips on this tank, so with my booting it and the engine not being warm for long, economy has suffered. Have no concern, I didn't boot it with a cold engine.

Noise canceling technologies and innovations are included in higher-market cars along the lineup. An X6 and 6-series are on the upper end of the premium spectrum, and the engines are designed and fitted with greater refinement. For example, the 535i spools much more quietly than the X3 35i. Exhaust note and engine note are more refined on the 5 than on the X3. Same with the X5. The X5 35i is a tad quieter when spooling up than the X3 35i.
