Hello there, my shop is currently working on a 2020 Tesla Model 3 with MCU version 2. The date of manufacture is 12/2019.
We are having an issue where the A2B bus is being shorted to ground. Resulting in the overhead microphone and rear amplifier not working.
We have purchased an identical used MCU, we are planning to swap the mainboards and reuse the existing modem.
I read in another forum that @McDangle was able to swap the MCU but the car had issues.
Does anyone have any suggestions/manuals/info?
