If its a ball bearing turbo you will hear a noise once the car is off, normally it's the turbine wheel slowly spinning to a stop. You should be able to hear the noise slowly going away as the impeller stops spinning

Yep that's what I'm
Doing tonight

The sound of the bearing is amplified if you have an aftermarket intake eg pod filter, metal intake pipe or a high mounted turbo.

Cheers mate

if per4manz did it, then something has probably come loose, like the nut holding the compressor wheel on or even the bolts holding the housings to the core.

sadly I have heard of turbos from there coming loose lately.
