Should I allow the turbo in my SEAT Leon to cool before switching off the engine?

Should I let my turbocharged SEAT Leon 1.2TSi's engine idle for a minute or so to allow it to cool so the oil doesn't carbonise due to the heat?

It has a water cooled turbo as well as oil cooling the bearing, but the answer is yes. After a long ascent, after towing and after a long run on the motorway, either idle it for 30-90 seconds or drive it at low revs through a town.
