There is no "cooling system" for a turbo. Turbos cool down during idle. Doing this prevent the oil in the turbo from overheating and caking.
Quick starts and stops are what kills turbo bearings.

I do it to keep the interior cool during the summer and warm during the winter. I’d do it if it was gas too

Personally, I do it because I hate the planet.

I’ve had diesel trucks for 20 years and I don’t really know anything about the engines. I’ve been told, though, that they last longer because diesel doesn’t burn as hot as gasoline. This is true when lighting a brush pile on fire, so I tend to believe it. I always leave it idling if I know I’m going to start it back up within half an hour or so because I’ve been told they are better off running than being cranked repeatedly. And the sound of the motor is a redneck mating call.

What really grinds my gears is when I see a cop car just idling in a parking spot outside a business. I'm paying for that shite and I'd appreciate if you try and conserve a little bit.
Equipment has to remain on and plays hell on batteries if you dont leave them on.....no cop wants to ask someone to jump them off so he can respond to a call.
Also some gear can't be left in a hot car.

just because you are that big of a retard....
Explain to me how oil on the bearing of my turbo can continue to circulate.
How will my LPOP work with the truck off?

Yes. I get asked repeatedly by my redneck friends why I didn't get a diesel truck.

Welp, I can tell you haven't rented a car in the last five years. All those cars shut down when you stop.

While Texas Transportation Code Section 545.404 prohibits drivers from leaving their car unattended without stopping the engine, locking the ignition, and removing the key from the ignition, at least one Texas court has held that this section of law only applies to vehicles parked on public highways and streets. The Cities of Dallas, Austin and Arlington have also interpreted Texas Transportation Code Section 545.404 in a similar manner.
And the provision in the law that defines the applicability of the law you linked:

I don't know if that's true or not, but one time I had security call the police at a hotel restaurant because I had the car running unoccupied.
Police showed up and I explained I remote started the car from inside I had the officer press the brake pedal and the car shut off.
None of them had seen it before.
Still wasted a half hour of my night.
It was in 1997 w a 94 Impala, remote start was rare.

In modern diesels there are mainly two times that idling is beneficial.
After towing or running up highway mountain passes where the transmission is kicking down a lot.
The reason for this is as others have mentioned the potential to coke the bearings as a result of overheating the oil in the turbo bearings. Most modern light vehicle engines have active means of combatting this either via a supplementary pump or thermal siphoning which covers you without idling except in the extreme cases I mentioned.
Warming up shouldn't be much of an issue in LA but in cold climates 3-4 minutes can be helpful but much more and you run the risk of clogging the particulate filter and EGR coolers quickly, both are expensive.
Outside these two times idling increases the frequency of particulate filter and EGR issues and also runs the risk of cylinder wear as a result of wet stacking/washdown.

Learn about Diesel engines, baw.

There is not yet enough data on what that energy saving design will do to the life of a engine over the long term. The manufacturers say it is not harmful, but that probably means for the majority of drivers that will only dive a car for 60K miles, and trade for a new vehicle, it will be interesting to see if any of those cars make it to 150L-200K miles.
