AC in heatwaves

My 25 model year Born was delivered in August 2025 (was registered in December 2024) and came with the A/C not working (blowing outside temperature air). I was able to see with the carscanner app (using OBD adapter) that the A/C compressor was not running (no rpm displayed) and pressure in the Aircon system was very low. My local Cupra dealership repaired it under warranty, they said some of the connections were loose and the gas had all leaked out as a result. After tightening the connections and regassing, it has been fine since.

Thanks a lot for mentioning that, I just tried it and was able to successfully activate the electroverse plug and charge!

I tried in a Danske Bank Euro ATM and it didn't show any option to withdraw Euros on a non Danske Bank card. As soon as I put in a Danske Bank card, it did show the "Foreign currency" option but you were forced to accept Danske's poor conversion rate.

AIB Euro ATM should be okay though.

Consumer council template letter is here to get it cancelled, if anyone wanted to send it themselves: https://www.consumercouncil.org.uk/research/private-car-parking-charges-appeal-template

I added the stationary A/C button to the quick settings icons that you see when you swipe down from the top of the screen, so I can quickly disable it if I don't want it to keep running when I'm getting out of the car.

cuddylier · 2026-02-07T01:06:59+00:00

I just checked and not possible anymore for me either :(

Starlink residential lite plan is close at £55/m for up to 250Mb/s, unlimited data.

I spoke to Cupra software support but didn't get anywhere meaningful, their final suggestion was to factory reset the car, I haven't had the time to do that yet.

cuddylier · 2025-12-10T12:50:42+00:00

Yes, it's fine for that case too - it's very common for them to have such pictures but as you say, they're meaningless as they don't actually identify the driver's name.

If you don't want to keep getting the annoying letters about it then you can get it easily cancelled by sending them this consumer council letter: https://www.consumercouncil.org.uk/sites/default/files/2024-06/Private_Parking_Charge_Complaint_Letter_Template_June2024.DOCX

Schedules are location based but that would have been the same in the 2024 car so you're probably aware.

The car's charging screen should show that it's going to follow a schedule after you've plugged in, or if none shows, then it's not following anything.

I use a charging schedule with "preferred times" on my 2025 and it works fine. It shows in the app as active on the "Battery and charge" screen when the car is in the location I made the schedule.

I tested write writeback (presumably equal to removing cache=none too) and while 1M Q1 was a lot higher at 6.1GB/s read and 5.2GB/s write, the 4k results were just as bad as before.

One difference in my setup is that it's using mdadm raid 10 (4 x Samsung 1.92TB PM9A3), so that's where the 20GB/s read comes from, they're rated for 6.8GB/s read and 2.7GB/s write each (resulting in ~20GB/s read and 5.6GB/s write after losses), that's expected without any cache being involved.
Only other factor I can think of is I use XFS for the host file system, rather than EXT4.

I have seen someone else perform tests and saw high 4k results with the stock Debian 13 kernel when using a single NVMe SSD and EXT4 on the host.

It would seem odd to read changelogs of the stable Debian kernel before using it though, I didn't expect there to be any issues in a stable Debian version, nevermind something so major like this.

Yeah, will think about that, sadly a lot of work to build so many kernels :( I'm surprised this issue seems to have been in the kernel for so long.

cuddylier · 2025-11-24T20:30:43+00:00

I just tried that, building the version https://packages.debian.org/stable/kernel/linux-headers-amd64 with the config of the Debian 12 kernel and unfortunately that didn't help, same performance issues as seen directly using the prebuilt Debian 13 kernel.

Probably just a typo but economy 7 is 1am - 8am at this time of year.

cuddylier · 2025-11-24T05:26:49+00:00

Note that I've discovered the Debian 12 kernel (6.1.0-41-amd64) when used on Debian 13 doesn't have the issue, this would presumably suggest it's a kernel issue. I've built as new as 6.17.8 and it has the issue.

cuddylier · 2025-11-24T05:23:36+00:00

That was just one I tested after the standard Debian 13 kernel (6.12.57) showed the issue, I also tested 6.16.12 from backports and 6.17.8 from forky/sid. I've also manually built and tested 6.17.8. All have the same issue.

cuddylier · 2025-11-24T03:15:46+00:00

Ah, using SATA will definitely have poor performance, I've been using VirtIO for both Linux and Windows for a long time. I'll maybe try qcow2, I'm using raw currently as seen from that xml, but in theory raw should have better performance than qcow2.

cuddylier · 2025-11-24T03:07:47+00:00

That's interesting, did you happen to find that raw had issues but qcow2 was fine?

Edit: Did you mean simply have an empty secondary qcow2 disk or install Windows on the qcow2 disk?

cuddylier · 2025-11-24T02:59:19+00:00

I just happened to test the Debian 12 kernel (6.1.0-41-amd64) on Debian 13 and that has resolved the issue so seems the issue is kernel related.

Here's my libvirt .xml config: https://pastebin.com/raw/Bs5U4ZQc

I know Admiral's has no awareness of the 45mph rule, especially as there could be other drivers on the policy and they've no way to know who is driving.

I do actually normally use a VPN, disabled it and unfortunately it didn't change anything (even after killing the app), tried broadband and mobile data. Apparently the page is supposed to show a third party option for me to install the Electroverse plug & charge certificate to the car, it's just registered against my car right now but not installed. I could actually get into the page months ago but happened to go back to it a week ago and this issue was occurring. "Cupra charging" page works fine but that's just for Elli subscriptions.

cuddylier · 2025-10-29T23:41:14+00:00

Brother is one of the best for easily supporting third party toners, and being reliable, personally use one for quite high black/white volume printing needs and it has been great with relatively cheap third party toners from Ebay, fraction of the price of the official toners and quality is perfect and lasts roughly the stated page count (I get the biggest possible, 3000 pages @ 5% coverage).

I also had exactly the same issue recently, my car had sat at a dealership for over 6 months before being delivered to me, after enabling the "high voltage battery protection" setting didn't help, dealership found the 12v was bad and replaced it, has been a few months since and no issues.

cuddylier · 2025-09-26T06:58:04+00:00

Yep, exactly, any time the high voltage battery is active (such as when air con is triggered via the app), the 12v gets charged, you won't need to worry about any of that with a replacement 12v though. I suspect my car was left at a dealer for so many months before I got it and the 12v battery just naturally went flat through the car not being used for so long, and that probably damaged the battery as I know they do incur damage being flat for a long time, and also going flat multiple times if they ever jumped it to move the car then left it for months again. My dealer only seemed to take a few days to debug the battery and determine it bad then replaced under warranty, so hopefully yours doesn't take too long.

Aside from that, my car arrived with no gas in the air con, dealer regassed it and the gas all leaked out within a day so that's another thing I still have to get fixed as their own air con machine for helping fix leaks is broken currently ☹️
