I made this post on the tesla.com forum yesterday:
MCU1-MCU1 replacement. Ratings - Local 8/10, corporate 1/10
My MCU1 died on Mar 4. Scheduled service the only way possible - via app. Was texted a mobile service appt from 515-519-7274 for Mar 16.
Mar 4 - Got another text a little while later asking me a few questions and suggesting I do a reboot (already done).
Mar 4 - Responded to that text, stating I'd already tried a reboot several times, and with some questions (including "are sure this can be handled by a mobile tech?") and never got a response.
Mar 11 - Text received "your concern is not mobile capable. Please use the mobile app to make a time/date work for you." First available at my usual SvC was Mar 23. Texted asking if anything was available sooner and received no response. Looked in the app at another nearby SvC and found an appt for Mar 17, and scheduled it.
Mar 17 - car dropped off at SvC. Offered a pre-AP MS loaner. Outside was immaculate. Inside was dirty. Asked if that text number is one way or interactive. Service rep said they have a team that should be responding to questions via text. They weren't. I expressed my dissatisfaction with the way service is scheduled and that there's no way to talk with anyone. Service rep commiserated with me and said most customers feel the same way. I was given the "secret menu" how to contact them via telephone. They also said they would contact me via telephone if I preferred.
Mar 19 - car sat for 2 days with nothing being done. Got a call saying they were able to reboot the car, but the memory chip was 80% "used up" and it would be prudent to replace the MCU. I asked about MCU2 replacement instead and was told it couldn't be done on my car. Asked to speak to the service manager. He (Ryan) was very pleasant and said if I could find a VIN of an AP1 car that had an MCU2, he'd look into it. He gave me his personal phone number to call back. Apparently the one poster on TMC who said he got a MCU2 was mistaken. Contacted Ryan directly via voice/phone and said go ahead with MCU1 replacement.
Mar 20 - Texted that car was ready. Total price was $1627.40 which included $1300 for MCU1, $8.80 for rear view camera HSD jumper, $7.70 for bluetooth antenna, $201.50 for labor, plus tax.
I asked them if they could rotate the tires as long as the car was in. Price for rotation was $133, so I said "never mind!"
On the invoice, it included courtesy checks including topped off wiper fluid (tank was already full) and tire tread readings of 0 (zero) across the board. I called them up (and they answered!) to ask if they forgot to record them on the invoice and they said it must not have been done. My tires have about 5K miles on them (and I have eyes), so I knew 0 was impossible
When MCU1 is replaced, all your settings are lost, including lifetime wh/mi :-( There should be a way for Service to save them, then transfer them. But no... Ironically, all their logging is the root of this MCU problem. Oddly, a few of my Slacker favorites were still there, but everything else from top to bottom, needed to be reset. I had forgotten what a few of the settings were, so had to look it up (the on-screen manual should have a search feature!) They forgot to turn mobile access back on, so I went into Safety and Security tab and scratched my head when I couldn't find the Mobile Access setting. Then the light bulb went off and I scrolled down and found it.
In summary, I was overall pleased with the local SvC. Service access and scheduling, from the corporate level, is horrendous. Grown-ups shouldn't be forced to communicate via app and text, especially for a luxury-priced car. This isn't an Xbox or Gameboy.

I find it disappointing that going through the official repair channels are a worse experience than going 3rd party.
My fix was cheaper, I got to keep all my settings and info, and I have systems access so I can perform diagnostics myself.
Tesla won't even pull their own data off their own products to provide a better experience.
hi-
I’m updating with a happy ending basically. Tesla got the part two days after they took my car in. Then it took maybe three business days to get the part in and functioning. My only hassle was getting back home and then back to Chicago to get the car. I had three different flights get cancelled... Not Tesla’s fault.
No surprises with the car. I’m finally driving home with my car today, two weeks later all said. No charge under warranty. No option to update to mcu2 at this time.

It would be great if the Electrified Garage could use the video to remove MCU and add how to remove and replace the digital FM radio. Many of us planning on doing the Infotainment upgrade and would like to install the digital FM radio since Tesla will not do it for us. I know that the configuration has to be change. I assume you need root access to do this.

As of this date, we've only heard of one person that has completed the digital radio swap. And no explanation how they got the car's configuration changed to allow the newer radio. And I don't think it was EG that did it or has done one. Maybe they will.

My guess is there will be a few
... But none of them will ever be service center performed, and like would not be any cars under warranty, and likely service center would not ever service them again.

Any done will be serviced under warranty. Likely not for a radio issue, but certainly for other things. I suspect that's what you meant. No radio warranty, but it wound not void the rest of the warranty.
If there's enough response from the existing owners that want the radio after the MCU2 upgrade, I believe Tesla will offer it. But I don't think it will come cheap. Radio at about $280, and two three hours of labor will be $400-$500. So for those that reallllllllly want it, they will do it. That's my guess. And it is just my guess.

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?

Correct, not yet. I figure someone would have detailed directions by the time more MCU2 upgrades are done. I've already read that 1 or 2 people have done it already as part of their own MCU2 upgrade projects before Tesla made the official upgrade announcement, so it is definitely possible.
So that will be 16-40 years on the early side. Hopefully there will still be people doing the repair then.

No longer recommending people drive while Tegra is out of the car since turn signals do not light on the exterior. updated on first post.
Wow really? Do the signals still work with a dead MCU but stop once the tegra is removed and MCU reinstalled? Or just stop all together when it does?
You would think that should be some kind of safety recall now
