This is all true but the BMW engineers created the LIMP MODE which will take care of most of these contingencies and more.
If you have a little too much fun at the track you will get LIMP or reduced power either way before you put the engine in harms way.

things to look out for :
- if your oil pump goes out while you're boosting, you stand a good chance of damaging the turbos. If you're not BB, then you're practically guaranteed some damage.
- if you drive super hard, and immediately turn the car off (without giving it at least a small cool down period), you can bake the turbos in their oil.
- if you ingest crap into your intake, it stands a good chance of not just 'blowing through' like it would in an NA engine. foreign object damage is a real deal.
