Preventive eMMC replacement on MCU1

[TonyT]

You can probably count on 1-2 hands... I know 1 in Quebec, 1 in Netherlands, 1 socal, 1 norcal (might have stopped), and 1 with videos floating around the web. The web one I don't know much about, but their video does show that what that do should work. So the appear like they are offering real service.

I just heard wk057 does this on the east coast.

OK, enough memory to last your car another 100 years.
No problems reading the old eMMC?

A word of warning.. Time is not on your side if your eMMC is failing. We just tried recovering files from emmc that has been driving around dead for 6 months. It was not good.... So best to do this when your eMMC is healthy. Once you start seeing symptoms, get it changed ASAP.

This is your PSA.

 

[TonyT]

Well Looks like my testing of pushing my original emmc may be coming to a end...

This afternoon my mcu may have went black and not come back... Good thing I know someone who can fix this. 149,1xx miles and about 6 years. Will update status later.

Again I was testing to see how long my emmc can last. I don't recommend other do this. I have verified my backups and ready to rebuild it.

Turns out my eMMC is not dead. And it's healthy enough to keep running. Was not booting up due to 12V battery not being charged since I have a HV Isolation issue. Car is headed to Tesla for repair, eMMC will keep on running!

Looks like the eMMC in pre-AP cars lasts much longer? My 2013 is also still on the original MCU and I haven't noticed any symptoms of it going bad.

Maybe the size of the firmware build for non-AP cars is smaller. My understanding is that the eMMC failure is caused by a combination of excessive logging and ever larger firmware builds, which fill up the stock eMMC, leaving less empty space for wear levelling.

And Internet streaming audio. So maybe people that only use USB media have a longer lasting MCU?

any idea if streaming audio via Bluetooth causes excessive logging?

I wouldn't think so, and @verygreen didn't mention that...

I do some streaming but not much. Maybe that's a part of why mine has survived also.

I streamed constantly on my original MCU1. It lasted 18 months and about 35,000 miles. Sample of one.

06-2017 X 100D (purchased 12-2017: service loaner)
I use Tesla AT&T internet Slacker streaming constantly on my original MCU1. I am not experiencing any problems that I know of.
23 months and 45,600 miles (but purchased with 4,000 on it). Sample one of two.

Feb 2013 Tesla S. 140000 km. Constant use of streaming music. No MCU issue. Slacker streaming music is all we listen to.

Had a 3rd party app installed on Linux constantly polling Tesla API for about 6 months a few years ago which kept MCU active.
Replaced my need for data with 3g cell network OBDII dongle from FleetCarma to monitor car, which doesn't keep the Tesla MCU active.

Firmware sizes for AP and non AP are the same. Generally 1 gig. I don't know that original ones last longer... Possibly but I don't think so.

 

[TonyT]

I stream all the time. But the logging is much worse.

Probably longer then that but I know I'll never need to fix it again

As for reading the emmc...Not really. Some settings were corrupt but caught it in time

Thanks to all for wealth of information in this thread, I've been following it since the beginning for informational purposes. My question is not completely related to eMMC replacement but in the same realm and because there are so many knowledgeable minds in this thread, I hope it fits:

Is there a possibility to upgrade MCU1 CPU? I mean, on a PC you can swap a CPU to a faster one with the same socket. Is there a faster compatible CPU for MCU1? If yes, is it possible to swap them?

 

[Krash]

...Is there a possibility to upgrade MCU1 CPU?...

This would be an extraordinary undertaking for very little benefit. There is a newer Tegra module card but Tesla has non standard pins. The processor itself is soldered, not socketed and if you replaced it directly it appearantly requires different supporting chips, hence the different sub board. Also there is some debate as to whether that chip would run Tesla compiled software properly: probably not.
