Has anyone had these two BMS errors before? I've been getting them intermittently ever since my MCU2 upgrade. The first time Tesla said it was an incorrect HVL node configuration in the MCU. They charged me for that without realizing they'd just upgraded my MCU the week before.
But the errors persisted. When they happen they happen for hours and power is reduced to something barely faster than my prius and regen is disabled.
It's at Tesla now. They say they can't figure it out and want me to authorize two more hours of labor to try and find the issue. I've read in the past these errors related to the contactors but now can't find those posts.
I'm tempted just to take the car back until it either fails and leaves me needing a tow or the errors come back without ever going away before I bring it back to Tesla to diagnose.
