Low battery
Battery level is below 20%. Connect charger soon.
· this weekend i opened the mcu, and shipped the tegra board to laadkabel in eindhoven (neederlands). The stock 12v battery finally died in my 2019 m3, apparently suddenly because i got no warnings on the screen. I put back the mcu in place with the lcd disconnected on order to have the 12v charged, so i can drive the car (with no heating nor ventilation). · mine was a b part number which said no screen, but one of the other line items detailed an mcu upgrade with screen. ~2 hours, difficulty 2/5 (great help with this video ) click to expand. · it seems like mcu failure as quick search from this forum pointed towards that. It does get confusing. see the invoice i got (tesla confirms infotainment system upgradeability from mcu1 to mcu2 for $2500). The replacement from tesla service center is asking $2900 estimate. Is there any diy/instruction/guide available how to swap it? I had just installed the latest update (2024. 23, i believe), then two days later, the screen wouldnt come on at all. Cant afford that at this moment. · i am planning an aftermarket audio upgrade for my 2018 model x with mcu2 (base audio system) and was wondering if anyone has a wiring diagram that would. Searching on ebay shown some listings around $400. The strange thing is that i could open the doors just.
