@tedsk is in the USA and did mine, turned it around really quick
See: Preventive eMMC replacement on MCU1
There is no 100% guarantee it will work, but I know skilled people who could do this.
Has anyone tried to just replacing the EMMC chip, then taking it to service to reflash a new image? If they ask what happened, don't tell them you replaced the EMMC, just tell them one day this just happened. EMMC's do fail (erase themselves) when unpowered in high heat for a while.
This would be a $3,500 replacement cost if you were out of warranty. We have already paid a couple claims for MCU replacements.
If you're capable of replacing the chip, you're probably capable of copying the image over np
Not if the EMMC chip is dead. Also, I have a rework station at home and I can take a BGA off and put a new one on, but it would take me a bit to create a setup to read a chip once off the board (socket it somehow, buy a BGA to pin header board and solder onto it, or solder wires to individual balls - all to provide power and route out emmc to an emmc contoller connected to a PC).
Reprogramming the EMMC should be cheaper out of warranty than replacing the entire MCU.
Save the planet Elon says, yet Tesla creates E-waste by the truck load because of bad programming and poor design choices.
My MCU just failed on my 2013 MS (46K miles). The 12V battery was replaced in March 2019. In August 2019 I got the "...replace 12V battery soon" message again. The battery had a 1 year warranty so the mobile service came to replace the battery at no cost to me.
After replacing the dying 5 month old battery with a new one, the Mobile Tech could not get the center display screen working again and told me that the car needed to go to the Service Center. The nearest one from Bellingham WA is about 60 miles away in Vancouver BC. My wife took it there and they said the MCU needed to be replaced at a cost of $4075 CDN. Ouch!
To confirm another post on this thread, when I requested keeping the old MCU I was told that I would have to pay a $675 CDN "core" fee to keep my old part.
I always thought than when you have already own something, that you don't need to pay someone to keep it? If I was Tesla's attorney, I would advise them to add the "core" charge to the the MCU price and offer customers $675 CDN to buy back the old part.
Core charges are standard for "valuable" parts in the automotive world. Some places do like you say and include the core charge in the price of the unit and then give the customer a core-return credit. Others list the core charge as a separate line item. The end cost is the same so either seems fine to me.
Wow. I keep wondering if I should proactively replace my 12v because it's over 7 years old. But I keep thinking the older ones must have been better build than the newer ones. How much did it cost to get the 12v replaced? And did mobile replace your 1st one?
Btw, I just had my MCU on my 2013 also replaced. Fortunately, under the ESA though. Hoping it lasts another 7 years.
Battery replacement was $210 parts plus $30 labor + tax (Canadian). So about $185 US + tax. The first replacement was in the Vancouver BC service center as I needed other work done (tail light assembly replaced $525 CDN, tire pressure sensors replaced $734 CDN).
Mobile service can replace the 12V.
This is the syosset location. I had that exact car as a loaner quite a few times.. Actually named it "return of the green hornet" back in March and just got it back last week... name was still there
Off topic but I just had my main display replaced for bubbles in the screen and hoping that my mcu doesn't go bad after then next 3k miles when my warranty is up
Actual price came in lower at $3,494.50 CDN for parts and labor. that's about $2700 US + tax.
Don't need to go to all that trouble:
And not that expensive:
All Socket DS3000
Note that the original Hynix chips don't like the All Socket SD-slot based programmer...
Finally some movement.
Flash Memory on Some Tesla Cars Is Reportedly Burning Out, Causing Major Issues
There are companies out there that fix this problem. A lot cheaper than Tesla does if out of warranty.
UPDATE: Tesla Cars Have A Memory Problem That May Cost You A Lot To Repair
So, maybe we should initiate a class action for this to get fixed. I have no idea how to do that, but will help if it makes any difference.
I just saw this piece about the Model S having an issue with the flash memory after 4 years and pretty much shutting down completely. They paint it as a major, widespread issue. But I believe that if this was the case, we would have more people talking about it here, like with the yellow screen or faulty door handles.
Anybody experiencing this?
