2007 audi a4 2.0t cvt. do i need to idle the engine to cool down the turbo?

Hi, i purchased the car mentioned above and i was wondering whether i need to idle the engine for about 30 seconds after driving the car in order to cool down the turbo. thanks.
Answer
Heat is the enemy of all turbos. if you have been horsing the engine then it is a nice idea. under normal driving conditions the turbo is continuously cooled by your coolant system. older turbos were not liquid cooled and so they cracked from heat more quickly. enjoy your new car.
