By no means an expert, just asking..
Good, valid question. Oil temps will rise if you idle for several minutes, especially in hot ambient climates. Which is why it's probably best to take it easy the last 5 minutes or so before reaching the destination. This, as mentioned above, lets the turbo cool down from the airflow around it whilst the car is mobile. If you do this, then you really just need to let it idle for a minute before shutting off. That's what I do.
I do notice in the hotter climates, if I sit stationary in traffic, the oil temps rise quickly and the intercooler begins to heat-soak, greatly impacting on power and response
