2016 C300 Check Engine Light After Disconnecting Battery?

Hey everyone!

I recently popped the bumper off my C300 to install the diamond grille. As a precaution, I disconnected the battery during the installation. After I put everything back together and reconnected the battery, I now have a check engine light.

I tried resetting the old fashioned way -- disconnecting the battery and leaving it disconnected for an hour or so. No luck.

Any other thoughts on what might be causing it? Thanks!

Looks like the light went off by itself after driving for a bit!
