You are wrong, he is right. It is due recent sw update. Error is readonly, you cant erase it without Tesla Service Center. Check my previus video.It’s not due to recent software updates. I got the same errors last year and they’re too generic to always map to a specific issue. Remote diags pointed to failing battery coolant heater as well so it was replaced under warranty. If you’re up for a DIY replacement, the HV piece shouldn’t scare you away. Just disconnect the fireman’s loop and shut the car down ahead of time. It’s the coolant mess that would deter me.
