Just FYI: The N57 is a bi-turbo. One small turbo for low revs (no lag), one big for high revs (less power dropoff).
And no, there isn't really any special treatment required like a turbo cool down or whatnot. Just follow what the owner's manual says. You shouldn't be idling any engine for long periods anyway. Waste of fuel and bad for the environment. |

After highway driving, I still like to follow the habit of idling my 3.0d for about 3 -5 min.
Regular oil changes will also help. I also could not believe how dirty my air filter was when I replaced it two nights ago. It was a miracle that the engine was still running. There were all kinds of debris clinging to the outside of the filter. I truly do no believe bmw's policy of changing the air filter after every 100 000km, can be good for the engine. just my 2c |

Diesels flow a lot more air than a comparable gasoline engine, and are a lot harder on air filters as a result.

Not necessarily turbo specific but more regular oil changes than BMW recommends especially with one after the first few thousand miles. I'd also say that if the car has been driven hard easing off for the last few miles is sensible....also letting the car warm up properly before maximum revs etc.
