Buzzing whining sound when engine shuts off

I have a 2009 R56 that makes a buzzing/ whining sound (like something is spinning is winding down). It’s very loud and noticeable in the cabin and outside the vehicle.

I found this YouTube video
with the sound captured perfectly but the solution provided doesn’t solve the problem. I replaced the turbo wastegate solenoid and it didn’t fix the problem at all.

Anyone our there have any other suggestions?

Thanks.
