SEAT Leon - belt or chain

Read with interest your car review on the new Leon. See that you are still attributing the car with the 1.4TSI 122bhp engine and not the 140 bhp COD. Assuming that it is getting the latter engine I see...

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?
