Shut Down Noises

Had the hood up on my son's 11 duramax when he shut the motor off. I could not believe the little noises coming from the engine after it was shut down. Sounded like some small motors or solenoids going thru their paces. Went on for about half a minute. I'm sure it was all normal just weird. Someone with a '11 6.7 do a listen and post if their are any little noises going on after shut down. I'm curious.

Also hear the DEF being sucked back into the tank, at least I think that is what the noise is.

Didn't catch that one on the chebby, will have to listen more carefully. I figured most noises were due to emissions controls.
