Thanks,

I'm a bit surprised at the comment "improper rundown and shutdown of the turbocharger"

I would have thought that every pilot flying a turbocharged aircraft (or driving a turbocharged car) would be aware that the engine should be run for a period of time at tickover speed to enable the oil in the turbocharger bearings to cool before switching off. More turbo failures are caused by not following the above advice than by any other cause.
