I remember when they said revision C of the drive units wouldn't break...... They are up to revision Q now.
Actually.... T on one of our cars...

Hi there knight owl! I see you're in colorado springs as well.... have you found anyone to do an eMMC repair in colorado besides tesla service center? I think mine is going bad :-(
Yes it does. That's heaping a lot of information into one word though. The MCU1 eMMC is an 8 GB chip. The MCU2 eMMC is a 32 GB chip. So, while it will eventually - as you said, fail, its expected to last 4-10 times longer before that fails.
Curious. Do you have a plan or idea on how to go about getting the digital FM radio to work?
There is no hardware 3 version of the MCU.We have a Sept 2017, model X. In early 2020, the MCU was retrofitted with the Hardware 3 version. Is the eMMC also upgraded and to what level if so. Originally the car had Hardware 2.5. Were Hardware 2,5s using 32 GB chips.
I have been skimming through the thread and not noticed if this is an old question. Thank you

you can find your mcu version -
settings -> software -> additional vehicle info
(just under the vin)
infotainment processor will tell you what you have. NVIDIA is MCU1.
It's a Nvida Tegra. Also noted 'Full Self-driving computer"
What eMMC goes with this package? Thanks,
Thanks for the clarification.eMMC is part of the MCU. (Unrelated to AP2/AP2.5/AP3(FSD) hardware.)
There is no way to see what eMMC you have, but unless the MCU was replaced recently it is likely the standard 8GB one. (I'm not sure if the "bad" batch of chips extends as far as 2017 or not, it seems for sure it is most of 2015 and 2016.)
Is this a sign of EMMC failure? I've already had one incident of a black screen/non-responsive touchscreen described earlier here about a month ago. It's been fine since.
But I just took a 300 mile trip yesterday, and I noticed two things. On the "consumption" graph on the MCU, the estimated remaining range, if over 100 miles read: 10— but when it dropped below 100, it read correctly. Also, last night on the main UI screen, a couple of the buttons (the pop the frunk and one or two others) looked like chinese characters. But when I got in the car today, they were fine.
I guess what I'm asking is, what is the criteria the SCs use to trigger an MCU replacement under warranty? How bad does it have to get? I'd hate to get stranded somewhere.
Pretty sure my eMMC is bad. Just wanted to post this for anyone else that might be seeing these symptoms that led up to it. This is a 2015 Model S 85D with ~55k miles.
For the most part, everything has been working as expected. I did get the occasional garbled text issue that was fixed with a reboot, but I haven't seen that issue in a while after one of the updates. Starting about two weeks ago, I was unable to connect using the mobile app. Didn't think much of it as I don't use the app that often, but yesterday I noticed it still wasn't connecting so when I got home, I decided to troubleshoot. The first thing I tried was turning mobile data off but it kept saying my username and password were incorrect even though I'm 100% certain it was the correct username and password. I also tried signing out of the mobile app and back in, but I was still unable to connect to the car. I then tried an MCU reboot, which took a while but seemed to reboot just fine. Still unable to connect via the Tesla app and I was still getting the invalid username/password error when trying to turn off the mobile data option in the car. I then attempted a "deep reset" (pressing the buttons above the scroll wheel and pressing the scroll wheel). The instrument display rebooted just fine but the main display went blank and never restarted. It was getting late so I just left it as is, thinking maybe it's just taking a while to restart. I woke up this morning and tried leaving for work, but the main display is still blank. Tried rebooting the MCU again but nothing. When I press the brake, I can hear the speakers make a faint popping sound, the lights on the steering wheel controls light up for just a second and turn off. It's like the car is trying to boot up but immediately fails.
Unfortunately the car is not drivable. I can't connect via the mobile app to schedule an appointment. Tried calling the local service center but no one is answering so I left a message. Also tried calling roadside assistance but after waiting for 15+ minutes, I hung up since I'm sure there's someone else that's actually stranded on the side of the road that probably needs more help. I'm still under a warranty (I purchased the car used through Tesla with the 4 year/50k warranty), but it seems trying to get a hold of someone is near impossible at Tesla. Pretty frustrating experience even though I knew it would happen eventually.
For the past month, about once every two days, my screen is freezing, requiring me to reboot, after which my screen works fine for another day or two, then it freezes again. Is this a sign that my MCU is about to fail? If so, does anyone have any idea how long until that failure occurs? I'm looking to trade my car in but want to wait until after battery day but I'm afraid my MCU will fail in the meantime.
Exact same thing my SC told me.Add me on the list. Dropped off my board to Tony yesterday.
Also anyone has a LTE upgrade board to sell or know a SC that will sell you one. Checked one local SC who said it was a restricted part and that they had to install it for a total of $500+ because it needs to be configured after installation. Told them my MCU was out but they didn't care, $500 please.
