Clicking Noise After Shutting Engine Off?

What is that clicking noise after I turn the engine off? I have had a 2014 CTD and I don't recall hearing that noise. Sounds like something is clocking back and forth a few times after shut down.

It's the shutters in the front grill closing. 19-22s have an active shutter system.
