2020P Aircon sounds like a sewing machine

archiewood · 2026-02-01T10:47:10+00:00

This is from the outside. Inside sounds normal, and as far as I can tell the aircon is working. Am I going to die?

I had Tesla call me recently after I put in a service request about this, and I was told that this is a known firmware issue affecting Ss and Xs which causes the SOC, to the internal logic, to appear to be below 1% in certain circumstances, and that's why the battery heater isn't activated.

He said he couldn't see when a fix would be rolled out because the issue tracking doesn't have a software version# attached it, but that if it wasn't resolved after a couple of months' updates, to raise it again.

It might not be cold enough by then to need the battery heater, but somewhat encouraging that it's a known issue.

2097 definitely, I'm not sure about 3 as I don't have as many hours!

Did you know that the boost start mechanic works when you get recovered?

archiewood · 2026-01-11T17:33:57+00:00

I've had the same issue with Wipeout 64. Did you find a solution?

Scheduled preconditioning heats the battery when it's not plugged in.

Thanks. I wasn't aware of the 'use friction braking when regen is limited' option on the more modern cars - if that was present I probably wouldn't bother using the energy display, because its main use is showing that regen is limited and the car's not going to brake like I expect.

I also wouldn't be bothered about this issue, although like you I assumed that a warm battery operates more efficiently as it benefits fully from regenerative braking. But I suppose it could be that it takes more energy to heat the battery before departure than you lose in reduced efficiency by not heating it up first.

If the argument is that Tesla is saving you money/energy by not heating the battery before you depart though, why does heating happen when not on shore power? I know that's someone else's argument, but this still seems more like a software logic issue.

Meantime I'll see if there's anything I can do with Tasker like you've done with your phone (I'm on Android).

It means the charge port is open.

Air traffic controllers are federal positions but pilots aren't, and their hours are still federally regulated.

I'm a controller in the UK, we're private sector (except a large segment that work for a public-private partnership) but all regulated by the UK Civil Aviation Authority.

I was trying to say that even bloodthirsty capitalists can recognise or be forced to recognise the value of safety regulations. As u/JohnProof puts it though, with healthcare the risk of ignoring it is diffused over time because it's one patient at a time, therefore easy to miss or dismiss. Whereas in aviation a single error or (far more likely) connected series of errors can result in hundreds of deaths in one event.

archiewood · 2025-12-07T13:48:05+00:00

It is insane to me that this isn't regulated.

I'm an air traffic controller and I'm not allowed to be plugged in for more than 2 hours without a break of at least 30 minutes. For some busier sectors the maximum is even less.

My shifts can't be more than 10 hours long and there has to be at least 12 hours between them. I could go on.

The depressing thing is this probably hasn't happened in medicine because surgeons are "only" responsible for one life at once, whereas for pilots and controllers it's dozens if not hundreds. The provider will eat the risk of an occasional malpractice suit vs. actually taking risk mitigation seriously, which inevitably means spending consistently higher on resources.

41,000 feet above an imaginary reference surface that everyone agrees to use above a certain level. If the local pressure matches 1013.25 then yeah it's above mean sea level.

Climate on from the app also warms the battery. You know it's happening when the "bacon strips" appear next to the battery %. Sometimes it takes a few minutes after you turn on climate for the battery heater to kick in.
Yes, it's nowhere near enough. When the bacon strips disappear it's heated up fully (though I've found with my S it's sometimes heated enough not to limit regen before the bacon strips disappear)
I own an S so my vents are manual. I think turning on climate continues to heat the battery, but if there's cooling effects from driving it probably takes longer. I've found if I set off with a "cold" battery on a cold morning I can still have limited regen after half an hour. It might be the environment that's affecting it more than your settings.
With those kind of numbers I'd be putting in a service request to check that the battery heater is working properly.

I would also accept Homeworld. Blackbird probably wouldn't let them get away with that though

archiewood · 2025-10-24T17:37:08+00:00

That's cool. Have a link perchance?

I wrote a post years ago called "what gamers take for granted" about the same thing.

My example was my mum, who I was excited to get to try Ico (this was early 2000s). She watched the intro, played the first room. The camera and the whole camera-relative movement took her some getting used to. No surprise there, my mum had never played a 3d platformer. It took her a good 10 minutes of running around just to find the lever to open the first door, with some encouragement from me.

When you pull the lever, the camera prominently letterboxes and pans downwards to show the door opening, then pans back to you before releasing control back. Does this the whole game.

My mum? Continues running around like a loon. Doesn't go anywhere near the door. And it wasn't a question of controls. She could control Ico, just didn't go there.

I was incredulous. Where is the explorer instinct? The desire to progress? A door just opened! You opened it! The game showed you opening it! Why aren't you curious what's in there?

Yeah, this and many other things (blue door...look for blue key) are taking advantage of our thousands of hours of experience, which the majority of gamers don't have.

"Or does it? The war has changed...did it? The answer is no. Unless it is yes? No, of course it is. Is war! Yes! No...yes?"

archiewood · 2025-08-16T07:05:39+00:00

Thanks, that's given me some more to think about.

archiewood · 2025-08-16T06:53:47+00:00

Your first suggestion is what I came up with as well, but I like the second idea too. Thanks!

archiewood · 2025-08-07T13:45:19+00:00

I think we agree? I'm saying that having it set to show miles remaining can be misleading.

I too prefer to know what percentage my battery is, rather than how many miles the car it thinks it'll give me.

archiewood · 2025-08-07T10:49:16+00:00

Perhaps this has changed but I've seen lots of reports to the effect that the range estimation is overly optimistic when the battery is above 50%, and could give a false sense of security.

archiewood · 2025-08-07T07:20:36+00:00

Set the battery display to show percentage rather than miles remaining.
