I picked up my S40 T5 AWD the other day. This is my first turbo and I know reliability has improved with the later model turbos. Do the new turbos need to cooldown before switching them off? What kind of driving / length of trip / other factors would bring the turbo to the point that a cooldown is necessary? If I drive under those conditions, but the last few miles of the trip the car is driven a little less hard, does that contribute to a good cooldown?
Maybe turbo manufacturers could learn a thing from Microsoft, and have a message like, "It is now safe to turn off your car"
