This thread is really motivating me to pre-emptively swap out my EMMC. On one hand, I don't really want to mess with my car which is mostly working now, but on the other hand I am starting to feel like I'm driving a ticking time-bomb, it could fail me at any time, most likely at the most inconvenient time.
I know my friend with toolbox access was able to remotely identify my eMMC was bad. In fact I saw with my own eyes my VIN was flagged as having a bad eMMC.
If it was just the $400 it would be a much easier decision. A much bigger concern is getting stuck with a dead car when I need it. I think it's fair to say any out of warranty Model S with original MCU1 should not be treated as a reliable car, which can die at any time.

Where are you located? I would probably pay you to do this once my car is out of warranty
So, I ordered myself a new emmc, 64GB industrial spec, plan to clone my 8GB and TRIM the rest of the chip so the remaining 56GB will be used for wear leveling. If the swap works, it should outlast the car even if Tesla doesn't curb their logging.
Normally I have scheduled charging enabled for 2:00 AM. Given this information, I am going to keep it disabled until I actually need to plug in and charge.

This is excellent info. Do you have a link to reference this so I can keep it in my notes upon secondary failure of my mcu.
I'd read this... Any Parts repaired or replaced under the Tesla New Vehicle Limited Warranty, Tesla Used Vehicle Limited Warranty, or an active Tesla Service Plan is covered for the duration of that applicable warranty or plan, and does not extend beyond that duration.
When my eMMC failed, I was able to drive, despite not being able to enter a PIN (and P2D being set).
Are you doing all of the work yourself or is there a local third party mechanic that can help with this? I'll be following this closely since I may need to do the same thing in about a year. I don't plan on getting the extended warranty at this point.If it was just the $400 it would be a much easier decision. A much bigger concern is getting stuck with a dead car when I need it.

Do you know if this is more a function of time or mileage? Put another way, does the car log substantially more when driving vs. just sitting there? I’d assume yes, but don’t really know...
Plan to do it myself, probably in the next month or so. Don't like the feeling of knowing that one of times I'll get into the car it just won't start. The car is 4.5 years old, and already running slow (though this could be just v10 in action), so it could fail any time now, and once it fails the EMMC cloning is likely to get much harder (depending on how much of it becomes unreadable). Also thinking of enhancing the Tegra cooler with a peltier module, but that might not happen (not sure how much space there is inside).
