I fixed my BMW i3 High Voltage Problem for FREE

My BMW i3 came from the auction with some major issues. First, it didn't even power on and there was no life from the car at all. After getting the 12 volt battery jump started from another battery and charging it for some time, I was able to get the BMW i3 to actually turn on and show some sign of life! This was very exciting, but what came next had me scared. I had multiple high voltage battery errors and BMW's Drivetrain Malfunction error messages (Drivetrain: Stop Carefully) that just wouldn't go away. I was afraid I would have to drop the battery to fix the pyro fuse to fix the Terminal 30c code (21F0CB) that indicated that there was a serious crash detected and the battery cannot be switched on (High-Voltage Battery Unit: Crash Massage, Serious Crash Detected). This meant the battery would not charge and the car cannot be driven. Luckily I found some diagrams that showed me where the sensor for the battery went and I started looking around at the wiring.
This was a big moment for me. I found a wire that was not plugged in and actually cut in one spot. After repairing this sensor wire, I was able to start, charge and drive the car!
