Twin-turbochargers - do I have to worry about overheating?

I have just bought a new Honda CR-V. The vehicle has two turbo-chargers giving the 1.6 diesel engine the same power as the diesel 2.2. I have read in your column that it is essential to allow the turbo-chargers to cool down before switching off the engine.

The engine cuts out automatically if I stop at traffic lights, then starts when I depress the clutch to start again. Will this cause the oil to dry out and damage the turbochargers? How long will I have to wait for them to cool down after driving in town?

The engine will have stop/start and that will not switch off if the turbos are too hot. Generally the only time you need worry is after a long ascent or after towing when the turbos will be at their hottest. At low town speeds the turbos will never get hot enough to have to worry.
