From Tesa's service bulletin I found these parts; looks like 3, but I thought they were all Hynix parts?Yeah. The new software reports when the eMMC is failing for at least some of the chips Tesla used. I heard there were three chip types. The message appears on your display if you have the lucky version. For the rest though, you never get the message and just have to wait for MCU1 to die. I have had dozens of crashes (and did an FPGA reflash that I would not recommend) and now have removed my USB drive at their their request which stopped the crashes, but of course now I have no no USB music or sentry/dashcam recording.
This is very useful, but after the recall conditions have changed. It would be nice to know the criteria for reimbursement eligibility (if you changed eMMC vendor, are you eligible?).From Tesa's service bulletin I found these parts; looks like 3, but I thought they were all Hynix parts?

2. Log in to Garage, provide the VIN, click VITALS > UI, scroll down to eMMC Vitals, and record the values to the right of Name and Reserved Blocks. If the name is not “H8G2d”, “Hynix” or “S0J58x”, continue to “Vehicle Ineligible”. If the name is either “H8G2d”, “Hynix” or “S0J58x”, continue to the next step. SB-20-21-002 Page 2 of 3 _ 3. If the eMMC name is “H8G2d”, determine if the filesystem malfunctioned due to wear. TIP: Refer to Toolbox article #53486 for diagnostic assistance. If alerts “MCU_w088_eMMCNeedsReplacement” or “MCU_w086_eMMCEOL” are actively asserted, recently asserted, or present in vehicle logs, continue to “Provide Rectification”. If alert “MCU_w031_cidSquashfsError” is actively asserted, recently asserted, or present in vehicle logs, AND there are fewer than 65 reserve blocks remaining, continue to “Provide Rectification”. If neither of the above is true, the eMMC filesystem has not malfunctioned due to wear, continue to “Vehicle Ineligible”. 4. If the eMMC name is “Hynix”, determine if the filesystem malfunctioned. TIP: Refer to Toolbox article #53486 for diagnostic assistance. If alert “MCU_w031_cidSquashfsError” is actively asserted, recently asserted, or present in vehicle logs, continue to “Provide Rectification”. If alert “MCU_w031_cidSquashfsError” is not present, the eMMC filesystem has not malfunctioned, continue to “Vehicle Ineligible”. 5. If the eMMC name is “S0J58x”, determine if the filesystem malfunctioned due to wear. If alerts “MCU_w088_eMMCNeedsReplacement” or “MCU_w086_eMMCEOL” are actively asserted, recently asserted, or present in vehicle logs, continue to “Provide Rectification” If neither alert is present, the eMMC filesystem has not malfunctioned due to wear, continue to “Vehicle Ineligible”.

Has anyone received reimbursement yet? I’d like to get my $2800 back for their defect.
This notice is to inform you that, after reviewing your request for reimbursement under Tesla’s General Recall Reimbursement Plan for the 8GB embedded MultiMediaCard (eMMC) in the media control unit, Tesla has determined that your request is ineligible for reimbursement because repair was not for condition described in Recall.
Service can fix this over the air if I recall correctly. It’s some sort of security key they failed to update.I had my eMMC replaced on my 2013. Ever since, my car doesn’t totally respond to the app. I can change climate, media, and the sunroof via the app, but cannot unlock the doors or open either trunk.
The app will show it was done, but the car actually won’t do it. About 20 sec later, the app updates to show the doors are still locked or the frunk/trunk is still closed.
This behavior has persisted over multiple MCU and IC reboots. Anyone have any suggestions before I reach out to service?
Yes. Same thing happened to me with my first MCU1 replacement. OTA fix is possible. I tried checking everything before I left the service center but that one was missed by me. You’d think Tesla service would have a checklist to catch things like this ...Service can fix this over the air if I recall correctly. It’s some sort of security key they failed to update.

I am happy to report that the service center indeed fixed it over the air for me. Thank you everyone for your advice! That was far simpler than I thought it would be.Yes.

check this outok gonna ask the question again, because I saw one thread on facebook with people saying (and some even showing photo) of getting their reimbursement checks from tesla already starting last week. Is that legit? I haven't got anything yet.
I got denied a second time (this morning was the second one). Do you have the exact verbiage I should be using?Anyone who submitted our invoice and got denied. Appeal your denial, restate all the info from your invoice, and let them know we tested your chip for failure, Then repaired your board with a new chip. We are working with Tesla to help them approve all our eMMC repairs.
I wasn't under warranty in either situation, so no warranty to break. Sure I wanted to save money, but I didn't think it would make my car unrepairable. Im pretty sure that taking the offer will make any future attempts at my eMMC 3rd party reimbursement null and void, thats whats frustrating.Cmon. They are offering to restore you from ‘unwarranted’ to ‘warranted’ for $100? Get off the forum and just take it. You did aftermarket because it saved you $ but you knew it broke the warranty.
