Default The arming mechanism for the explosives on your turbos. "Blowing your turbos" isn't just a figure of

speech.

I have always wanted a button that read:

"Push to test"

followed by

"Release to detonate"

Default Seems surprising no one has offered up a clue what the sounds are when you turn the key.

Yes, these are normal sounds we all get when we turn our cars on.

There are obviously many processes that initiate when you first turn on the ignition (including the throttle adaptation stuff), but I for one do not know the complete laundry list of what happens uner the hood.
