so i am a bit confused here. Never have i ever recoded anything after replacing the battery. Granted it was never on a Q7, but cars like A8, A6 (2006-2010)
What would happen if one replaced the battery but did not recode with VAGcom ?

Coding resets the battery management system, as the batteries age it lowers the charge voltage so the old battery is not overcharged as it looses capacity through normal wear/tear.. When you install a new battery without resetting the BMS it'll likely be undercharging your new battery.
