2021 M3 battery shot at 77K miles? Or my own fault?
I installed a Govee Underglow kit on R2 today. Shortly after I started getting warnings that the max charge was limited due to an HV error.
This is what’s on the service screen.
Is it likely this is related?
I have the Govee going straight to the LV battery, currently in-switched and “off” via the app. I will add a switch tomorrow.
I used the included small screws into plastic under the car. I don’t think I pierced the metal protecting the battery pack.
I also stuck the Govee controller to the metal brick next the to the LV battery. Perhaps I’m causing a heat issue?
Suggestions are appreciated!
