Oh.. I guess you dont know how turbos and the oil that cools them down work.

The oil that sits in the turbos when you immediately shut down the car is very hot. By the oil circulating in the turbos at a lower temp, this prevents cracks in the turbines. Which keep your turbo alive longer. Thus why people get turbo timers, or sit by their car while its stationary after a spirited drive.

Now my question is that I heard the 335i has a built in turbo timer or circulates cool oil through the turbos when the car is shut down. Wanted to know if that was true or not. So I dont have to get a turbo timer.
