Should a turbo diesel vehicle idle before been switched off?

Turbo charged engines must be idled down to allow the turbo to spool down and even out the temperature in the turbo this is done either by using oil cooling or the engine coolant or both in combination.The engine needs to be running to circulate the oil and coolant if you shut the engine down without idling the engine down it can burn the oil or coolant and in many cases both which will cause carbon blockages in the oil feed and coolant feed and hamper lubrication leading to catastrophic turbo failure (fires and explosions)
