After a bunch of reading (and frustration) with the lap timer/battery gauge VAG_COM changes, I discovered the lap timer has moved to the instrument cluster display and is accessible from the steering wheel controls. It's pretty nice! Hopefully, I can save someone some aggravation looking for it.
I gave up on finding the battery gauge...I don't know if it was pulled for the C7, but it seems nobody has been able to find it. Since I have stop/start, it seemed like a good 'geeky' thing to enable, especially since my last car suffered from persistent charging issues.
