Need advice: How far do you go preserving originality on a driver?

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2024 Volkswagen Golf R charge sessions. Then you'll know the next fork. Was this after sitting overnight? A day of patience here is cheaper than a wrong part. No warning lights, which is why I'm documenting it.

I'd treat 12V warnings as a no-ignore. On the 2024 Volkswagen Golf R, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. Then you'll know the next fork. On “how far do you go preserving originality,” that was the fork that mattered for me. The universe charges extra for guessing. I'll poke at it this weekend.
