Perhaps slightly more on topic

I had my first experience of VTL yesterday.
I have a 2022 LR Trophy about 3 months old and bought a VTL cable from
evcables.co.uk when I bought the car. I hadn't used it but yesterday having suffered several power cuts due to the thunderstorms I thought I'd give it a go. I plugged it in and ran the cable through my front door letterbox then via an extension cable into the kitchen. Hardly a permanent solution but good enough for a trial. Turned the car on, started the discharge then turned the car off and locked it. Power was still being supplied and I managed to use it to cook my dinner (in a 1.75kw Ninja Air Fryer if you're interested

).
I'd read about how it would drain the 12v battery in this configuration so I left the cable plugged in to see what would happen (without actually taking any power). All seemed OK.
This morning (as might be expected I suppose) everything went tits up.
Went to the car only to find it wouldn't unlock. Found out how to unlock it manually and tried to start it. Nothing! Checked the battery voltage, 9v

This was not good. Put the battery charger on and left it charging for an hour or so. This time the car powered up but the brake pedal didn't want to move and the dash lit up with multiple warnings. It did eventually let me move off gingerly but the brake had no servo assistance at all. So having moved it back up the drive I tried the 10mm spanner trick but to no avail. Time to call out the AA.
I was pleasantly surprised with the service and he turned up an hour later only to be somewhat surprised it was an electric car. Anyway I took him through what had happened and mentioned the various discussions on this forum. He plugged in his computer which as I expected wouldn't recognise the car. He typed in the VIN and had to select the 2020 version as my car was too new. The auto diagnostics wouldn't work so he worked through several options until he eventually found an error message for a low 12v battery in the diagnostics section. He cleared that error and lo and behold the car was back in action.
Definitely an education for both of us and hopefully him having reported how to rectify the error through their system, the AA may be in a better position to help others in the future. I've also learnt the pitfalls of VTL (and letting the 12v battery get too low) but I'm reassured that if used properly the system works well.
