i see. I ask this because so many people said that it is better to let the turbo to cool down before shutting the car off.
Btw, how long should I idle to warm up the car when staring a car in a very cold weather like -20 to -30 degree C?
holy crap thats cold....I'd recommend at least 10-15 or so min a good indicator is the heater producing heat.... and on the hot side its best to give the turbo 1 min or so before shut down after very spirited driving or cycles of high RPMs it allows the oil to cycle past the cooler and through the turbo again to cool it off.

I warm my car up until I see blue on the dash temp. and i always let it cool for a minute after normal driving and 5 minutes after spirited driving. Or you can pop your hood and look behind the manifold shield through the 2 holes, when it stops glowing red you can turn the car off. Ignore all of the misinformation thats been going around, the fans that turn on do close to nothing. Anyone that has had a car before their ralliart will tell you that the fans would turn on on n/a cars too. Yeah our cars are oil and water cooled which works to keep them pretty cool but when the engine stops running so does the oil and water and then the turbo starts to cook and cook the oil along with it.
