    Can all data/setting be saved by service during MCU replacement?

    A technical question for you technical geeks: To fix my ongoing CPU1 issues, local Tesla service just replaced my existing MCU1 with a new (i.e. recon) MCU1.

I obviously need to get the screen replaced and in reading through the threads on here it appears Tesla is now just swapping screens when possible and not touching the MCU. Since these two are so closely married and I have...
