Good 'ol vagcom. Did a lot of tweaks to my old Audi A3: No more seatbelt chime when in park, enabled running lights, tweaked steering weight and added remote window up/down.
I'd *really* like to shut up the non-stop engine on chimes on my 2017 volt. Even the quietest volume level is super loud.
Anyways, rant aside: There's an android app called MyGreenVolt which connects to a cheap bluetooth ODBII adapter. Gives you a ton of info and is all-around stat nerd candy. No way to change settings though.
