Keep in mind it's not that simple. Existing MCUv1 is a ticking time bomb, every single one. Imagine if your BMW radio or IC stopped working at the 4 year mark?

My Feb 28 2018 MS build is already at 1451 erases out of 3000 rated erases on my emmc. So I'm at least half way there to a dead emmc....on a 2018...that just turned 2.
it's a time bomb.

Do you do anything that prevents your car from sleeping? (Like third party apps that don't let it go to sleep.)

So the 3000 writes is probably a guaranteed number of write cycles when the part experiences the worst case conditions. Is that what that number is?
So we are truly exceeding by a lot the number of cycles that the part can count on. Yikes. Definitely living on borrowed time.

Right. "Pain and suffering" for not having "Premium Connectivity"?? #firstworldproblems.
Second, the only way you'd get court and legal cost is if you actually go to court and get a judgement, which is never going to happen over a $120/year fee. Third, just getting your "firm" to write that letter is going to cost you A LOT more than PC will cost. So stop the legal pomp and circumstance and just pay for PC if you have to. Taking a legal action for this just makes you look like a entitled, over-privileged, rich dude. Get over yourself.

How many times can you be wrong in this thread? You should just stop posting. First with the MCU2 retrofit, now this? PC is for the life of the car. If you get an MCU2 retrofit in an MCU1 car with PC, you're still going to have it. End of story.
PLENTY OF TIMES.. especially with BMW that provided THREE, count them THREE upgrades to their E39 in-dash navigation and entertainment systems (MK1 through MK4), as well upgrading the screen from 4:3 to 16:9.

I was told that Tesla actually uses the number 2800 internally as a threshhold for max write cycles.
Edit: And it looks like I'm wrong on that. The CID info posted is pretty clear.

I've heard 3000-5000 is what similar chip life is expected to be. Obviously an automotive application would be harder on a component.

Have you monitored it ongoing to understand the rate of change (approximate)?
Has it changed since the below situation happened? (elon's response)

It doesn't really matter if they curtailed logging (which they did as I understood). But the damage has already been done since you can't reverse the wear. I've heard that those who stream audio more, have higher write cycle numbers. Don't know if that's true, however, some of the owners I've spoken with have mentioned streaming habits and those who stream more have had failures sooner than those who use USB primarily. I will admit it's a small sample size, ~N=20.

I was talking about the *rate* (ie. speed of wearing). I said nothing about reversing anything. It could take 2 yrs to get 1/2 way (1451 vs 3000 in example above) but if they slowed it down then maybe it will last 4+ more years instead of 2 more years. Helps in long term planning.

I’m still on an earlier version from 2019, so I don’t know what effects the ‘upgraded’ firmwares have with regards to logging.
I exclusively stream audio.

The idea that a computer can be upgraded within a car by the manufacturer is *stunning* to most BMW owners.
Among E90 owners, the lack of upgrade ability of the E90 system is legendary. When I bought my 2011 E90, they offered “BMW apps” as an option so you could play music apps on your screen (I wanted Mog integration back when that was a streaming service and they had it). They required an iPhone specific cradle to work. I bought that garbage. I’m pretty sure it cost around $1,000. They came out with maybe one more iPhone cradle since, of course, each new phone required a new cradle before they abandoned the whole thing. We also have an E60, but just how anybody could ever upgrade that is beyond me.
I guess there was one more “upgrade.” Since 3G was discontinued a few years ago, they would either upgrade my service to 4G or offer me $100 or something, so I took the money and walked away. By then my hate for BMW was massive, but that has more to do with the shoddy build quality and evil service writers than anything else. I was even told, point blank, by a BMW sales rep that I should lease rather than buy because the cars don’t last past the end of the warranty.
I've confirmed that in 2020.8.x firmwares, there's a new car configuration line that enables/disables the new tuner for mcu2. That's how tesla is going to manage retrofits - so it won't be as easy as just wiring the new tuner and expecting it to work with mcu2 - you'll also need a way to change the car configuration on the gateway to change the configuration to enable tuner. BTW - it's counterintuitive, but, this is how Tesla is DISABLING the tuner:
Tesla will add "ethernettunertype 1" to the car's configuration and to revert you need to change it to "0", or just delete the line.
I know, strange that disabling it is "1", and enabling the tuner is "0", but that's what it is.
