My current car is a pre-LCI June 2005 218ps 3.0d auto. I just had a new Turbo fitted by BMW (- don't ask!) and I can clearly hear it whistle under both gentle and hard acceleration. To be honest, its louder than I would expect from the car, but its a new turbo so I assume its working as designed.

EDIT: My current car is remapped, not sure if that changes anything?


My previous car was an LCI 2008 525dA with the 197ps 3.0d auto, and I could only slightly hear the turbo under acceleration.
Same here. Actually I hear a soft whistle more often on gentle acceleration. On hard on accelerations, I seldom hear it because I tend to concentrate more on controlling the car as opposed to picking out turbo whistle.

cheers

thanks for your replies people - that puts my mind at rest quite a bit

I also spoke to some specialists today and they said most turbos whistle and the noise level also varies from car to car.

My turbo does actually get louder as I go from 2k RPM upto 4k RPM (even before the remap)

Should I just leave it and see how it goes or er... do something

I wouldnt worry too much about it unless you get a grinding sound rather than a soft whistle.
