30D - "rotating" knock on switch off

When switching off the engine of my 30D I frequently hear a rotating knocking sound from the engine compartment, it's like a pump spinning down - surely not the turbo...it would be wrecked if it were doing this wouldn't it? The sound lasts about 3 secs.

I would check it out immediately. My 30d don't do this. Sounds bad...

I'm pretty sure you've fixed it already but just curious what was the issue on 3.0d?!

On my previous X3 F25 2.0d i use to hear it every time but that prove to be a normal ''reset to zero'' of actuators and some other things in engine bay...

It's not fixed and your explanation is in line with what I think I'd happening.
