hi... i heard that on the first gen s4 it was recommended that u keep ur car in park and keep the car on at the end of ur drive for about 5 minutes to let the engine cool down, since the car has twin turbos. i find this hard to believe, but is it true?

Otherwise, with time the turbos will weaken. Just use a Turbo Timer.

Then let it run for 2 or 3 before shut down.

until the oil temperature needle moves off it's leftmost resting position.

At the end of any spirited driving, recommendations vary. Some say to get a turbo timer and forget about it. Others say to sit there with the car running for a few minutes. Still others (I'm in this group) suggest simply driving gently for the last few minutes before parking. In any of the three methods, the oil has a chance to cool down slightly, as shutting off the car and leaving very hot oil in the turbos is bad for them (for reasons I don't quite understand). Driving gently is pretty easy, as I'm usually driving through a parking lot or on city streets prior to getting out of the car.

The force is strong in this one, listen to him.

I wait until the oil temp is at 200, but that is probably overkill.

Not just on the first gen. - these cars are great but high maintenance.
