I have an OBD 2 adapter that allows you to use a bluetooth OBD3 reader that pulls data from the CAN buss when using the app Scan My Tesla. This allows you to view many data points about batteries, performance and so on. This is for the 2019 M3 or a 2020 newer Model Y. I used this in my model Y but since traded it in for a 2018 M3.
Now I'm on a quest to locate the adapter for the 2018.
