Tesla infotainment system upgradeable from MCU1 to MCU2

[zanary]

I'm interested if Krash's information on their MCU1->2 efforts is different than the initial proof of concept that already happened in the past.

We already know they've done it internally per Elon's remarks, but the question is are the revisiting it for a full retrofit to all vehicles (including AP0 and AP1 with the old wiring harness), just for AP2 -> FSD, or some other permutation.

we don’t know for sure but I’m speculating only AP2.0 and 2.5 Model S only.

I'm at almost 50K miles on my Dec 2016 car with MCU1.

This thread has me pretty paranoid.

If we don't get a MCU2 upgrade path, I'll be shipping my MCU off for the emmc upgrade this summer.

I'm not going to do anything until something actually breaks.

I pulled up the PDF warranty document and showed them their policy in writing. They politely admitted they had never heard of this warranty before and waived the charge.

It's shocking that they don't know their own warranty polices.

Thanks for educating another service center.

I wonder where the relay is... It doesn't sound like it was in the MCU itself, so maybe it shouldn't have been covered. But it is also weird that they wouldn't have billed for the replacement relay. (I don't think I have seen anyone report this particular failure before, we always assume the MCU/eMMC when a MCU goes black.)

He specifically mentioned pre AP.

He mentioned that they are currentlytesting it. That sounds newer than something that they have done in the past... It also sounds like we might get more information in a few weeks. (Or longer if they wait for the necessary parts to be produced before announcing the upgrade option.)

An MCU2 replacement for MCU1 cars is currently in testing at Tesla and still will be for the next few weeks. After it passes, Tesla may start production before announcing it. They may also release the upgrade for some configurations before others (for example HW 2.5 vs HW 2.0 or pre AP). Don’t bother your service center about it. They won’t know until it gets released.

Its now just a two weeks short of one year since Elon tweeted that they were working on a MCU1 to MCU2 upgrade path.

You mean just short of 4 weeks of 2 years since he originally mentioned it.

Yes, I guess I did. Thanks zanary. Good catch.

Aw crap. If that’s true, what are we going to carp about now?

How about Model S75 RWD produced before July 2017 getting performance uncorked?

You've been around long enough to know he lies a lot.

I’m thinking the “relay” was actually the fuse I pulled myself because the heat wouldn’t stop running when the MCU died. I left the fuse marked in a ziplock for the technician but perhaps they just discovered it was missing and replaced it? A fuse is not the same as a relay but who knows.

I really don’t like this whole only communicate through the app business. I miss the days of speaking to a knowledgeable Tesla service technician who actually took the time to explain what was going on. I think you get this more with the ranger service since they interact with you directly.

Thanks for the tip, you saved me $195 bucks!
I got very few details from service on the MCU failure, no actual communication with a technician and the invoice simply says "Replaced a relay within the wiring". I guess this somehow resurrected the MCU. They attempted to charge a $195 "diagnostic fee", no itemized parts or labor on the invoice which is a first for me. The $195 is pretty reasonable given the amount of troubleshooting and work I would imagine they did. When I pointed out to the service rep that the repair should potentially be covered under the 4 year "Touchscreen and Microcontroller" warranty since I had previously paid to have the MCU replaced, they questioned the existence of this specific warranty. I pulled up the PDF warranty document and showed them their policy in writing. They politely admitted they had never heard of this warranty before and waived the charge.

Thanks for sharing your experience... hard to believe that Tesla is not familiar with their own warranty coverage!

I'm actually not surprised. Some service center employees have only a little over zero knowledge about what they do.

I used to work for some Product Managers that provided specific items on a definitive timeline. They used to have a saying.
"PM's don't tell untruths, the true simply changes."

I was at the service center today (for FSD computer upgrade) and someone was claiming bumper to bumper including brakes for 8 years unlimited. Per sales person 5 years ago.

Did @Krash just remove a post?

 

[MikeBur]

Well at least the MCU you paid for out of warranty came with a 4-year unlimited mileage warranty, so they should replace it for you free of charge. (Actually I don't know if it would be free, the part should be free but the warranty on it might not cover labor. You'll have to let us know how it works out.)

I’m hoping there’s a written record of that 4 year warranty on replacement as I can no longer find it...

Then you aren't looking very hard. It is right on the Tesla warranty page: Vehicle Warranty

And contained in the warranty document: https://www.tesla.com/sites/default...sories-body-repair-limited-warranty-en-us.pdf

Of course it only applies to out-of-warranty repairs you have paid for, it doesn't extend the warranty on a warranty replacement/repair.

Okey, is @Krash with Morten Harket picture having a beef with moderator or something?

Got a notification that he quoted my post, but seems removed.
Earlier got a notification about a new post, but only to find out that it was removed also.

Bugs the hell of me...

No, I think it's all good. He replied to you a bit earlier saying he removed a post and also said he'd remove that post too.
