When just sitting in the car, not running, I also hear what sounds like some kind of actuator or servo, maybe even a drive spinning up / down (MyGig, etc), somewhere behind the dash.

It's periodic, both in Off and Acc, I'm assuming it's just the Wizard behind the curtain,
I'm assuming the logic state of the CAN bus changes with me opening door, closing door, turning radio on for a moment, pretty much anything, times out then normalizes back to whatever key state, etc.
:smoker:

It's normal. You'll also hear the thump of the sub as well. This is activated when you open the doors and it detects the key FOB I believe.
