On the second charging attempt, my car threw a bunch of warning/error messages. On the day I was to bring it in, I had some very serious sounding messages, but the car came alive and let me drive it. For a bit. I'm up at over 2,000 feet so the first few miles of driving is downhill with regen. The car did not like that. At the bottom, the car gave me a "Pull over immediately, I'm going to shutdown real soon now" message - which I did and it did.
But, the car did "start up" again, so I continued to drive it into the SC. Made it.
I picked my car up earlier today. They said that a connector/connection inside the battery/sheets was loose. They speculated that it may have come loose on my drive home when I went over bumps. One service advisor said that they had to call into Tesla Engineering for help and that they pointed them at a loose connection. Another service advisor speculated this wasn't the first time this had happened. They did open my battery up, btw, so my "warranty void if broken" sticker is essentially broken (unstuck and restuck, I'll have to talk with them about that).
They did a RANGE charge, but didn't take it all the way (something close to 300 miles). I drove it home with no issues. OVMS did a Cooldown with no issues. Set for a STANDARD charge tonight.
The should not be a need to draw down the battery to "reset" the range. The range will update as the CAC gets recalculated over time, but it's not going to be way off. At this point don't believe anything Tesla service advisors say about the car. Maybe believe the technician, but my group struggled with understanding how the cluster could say one range while the VDS said another. It was, obviously, because I have the cluster showing projected range from my last N miles of driving while VDS always shows Ideal.
I'm going to pull a log file now so the next one is all new battery.
