I did the CCS retrofit on my 2019 Model 3 today (with the bundle of wires and new ECU).
Sometime recently Tesla added a "CCS Retrofit" button in service mode. I was expecting to be able to use that to clear all the usual errors that occur after, instead of going through the software reinstall process.
But it doesn't seem to do anything. I did it twice and each time the car rebooted and nothing changed. The faults remained. My car is running 2023.27.7.
I then did the reinstall and that was successful. Tested L2 and Supercharging and both worked. And the car shows CCS Adapter Enabled. Just sharing here in case anyone else is wondering about that button in service mode!
I'm kind of curious if it's just a broken feature in service mode, or if it's meant to do something else.
