When my car starts, my shutters make some noise and open a little, but definitely nowhere near a 90 degree pivot. More like "cracking the window," just barely angled from flat. After a few seconds they go back to fully closed. They don't seem to open after driving either. I'm trying to figure out if this is normal behavior or if I should take it to the dealer. When others' shutters actuate on engine start, do they fully open or just crack themselves? I should note that I'm in about 40 degree weather right now, which may be contributing.
Thanks in advance.

Doesn't sound like your description is out of keeping with the functional objectives of the active grille - ie temperature mx and aerody optimisation
Excerpt: yes it's from the 7 but the concept surely isn't that diff
