Likely MCU Failure (MCU1 eMMC)

[David99]

how hard was the process of removing everything

With the right tools and some experience working on cars its not too crazy. If you have never taken apart the dashboard of a car it would be intimidating. I do a lot of work on my car and have helped other Tesla owners with repairs so it's straight forward to me.

Is @TonyT or you willing to state the price of the Swissbit chip and the LTE upgrade? I am still on 3G as well. Pm me if you prefer Tony; I am seriously considering making a big drive down there one of these days. (Yes I know I could mail it)

Your welcome to come down. We would really need to work out timing. Hopefully you can stay a bit and enjoy some vacation here. I'll send you pricing details and options.

And mail works too. I would only do the LTE if your here, if you don't come, you can easily do the LTE when you have it apart.

It's doable. I've had several people send me their Terga boards. I've also had someone send me their car since they preferred I do the whole process. He will probably chime in at some point.

I can offer full removal service, or just send. Either way works. I try to keep a process that works for everyone's time, skills, and budget.

Tony email me the pricing please

Just fallen victim to the same thing, dead MCU 5 weeks out of warranty. Service centre comms truly terrible (Brooklands, UK). It is likely that the eMMC chip was failing while still in warranty as firmware was six versions out of date. Requested goodwill contribution, but told that is not likely. Was about to buy a model 3 as a second car, but my faith in Tesla is seriously shaken, so reconsidering my options.

contact @LuckyLuke He can help you.

My MCU1 started doing random reboots recently. Last night on the drive home it rebooted 3 times in 20 minutes. I turned the car off via the display and let it sit for a few hours, so far it's good but hopefully not a sign of failure. Still under warranty at least.

Since getting a "new" MCU -- mine no longer does this... It took about 3/4 a year for it to die once it started doing that for me.

@NoMoGas Chime in already!

Yep, sounds like your probably getting a new one soon. This is a likely failure sign.

Actually he did, I didn't put 1 and 1 together until your post! lol

The same one I mentioned in Post 225.

Gents—

almost done yanking this thing out.

seems my fuse box is the long—slender type with id’s in the 100’s.

I’ve searched google and couldn’t find the touch screen/MCU fuse ID No—any idea which it is…?

 

[BlueOvalFan]

Ok...found the updated wiring diagram, but not the fuse description for the MCU / touch screen seems to have changed. Im about to just disconnect power old school, via the 12V battery post

edit:
Did it move yo the passenger fuse box; F235. Center display...?

Last night I got the new eMMC from Tony and my car is all put together again. I'm so glad I did it before it failed entirely. Tony was very helpful. He also upgraded my car to LTE which makes a big difference.
No more glitches, no more frozen screen, no more bluetooth and internet loosing connection. Most importantly I don't get stranded with a dead MCU which is inevitable with the chip failing. I should be safe now for the next 20 years.

I did most of the mechanical part of taking the dash apart myself.

Are we assuming the Swissbit will last much longer than the one it is replacing?

If you're going to disconnect the 12V, don't forget to disconnect the HV via the emergency responder loop, or the main battery can supply 12V.

The Swissbit is better quality that can handle more writes. It's also 4x bigger giving much more room to wear since the whole chip is used for wear.

Tesla is reducing logging, and seem to be working on the problem.

Lots of factors that should help.

Which will help future cars, not the current ones already damaged by logging.

Correct, the response was to the question if the Swissbit will last longer. And the updates will help and can continue to help more if Tesla continues to work on the issue. I forgot to quote since I posted right after the question.

I am planning to put in the 64GB Swissbit part in my 4.5 year old MCU1, but don't plan to expand any partitions (though TRIM the entire part before cloning partitions onto it). Given 8x the memory and higher durability part, it should outlast the car assuming Tesla doesn't make it worse (not always the case with Tesla software).
