I believe our turbos are water cooled and there is no advantage to letting it cool down for extended periods. Back in the day you would need to put turbo timers on your car for this reason. Unnecessary now. If you were tracking it hard and suddenly shut it off coking may be an issue. Normal or spirited driving no problem.
Turbo gurus can chime in if my info is incorrect.
