Many stories out there tell that the flash storage (eMMC) on MCU1 will wear out sooner or later. This is known with flash memory and at that moment your Tesla will die. It won't charge and possibly only drive in limb-mode.
I have a 2013 S85 and a 2018 100D and the first one still has an MCU1 which has been running for 5,5 years now.
If the MCU dies Tesla will charge EUR 3000 (I'm in Europe) for a MCU replacement while only a small memory chip has failed.
I found this blog: Replacing eMMC in MCU
The same is shown in this video:
I've just ordered 64GB of eMMC storage for ~EUR 80 and a AllSocket eMMC programmer so that I can re-program the memory.
I'll go to a local electronics repair shop to help me with de-soldering and soldering the eMMC on the MCU. I'm thinking about doing this preventive to make sure the car doesn't die on me while driving. It's not a question of "if", but "when" it seems.
Has anybody replaced the eMMC memory on their MCU1 and can share some more experiences?
