In my previous VW Tiguan if you were sitting in the car for 30 mins even with the radio only on, the car would shut down so not to run the 12v battery down

The same seems to happen with my ID4, with this current hot period I sometimes need to be sat in the car for 30 mins or longer without driving around. Can this 30 min timer be adjusted and does switching car off and back on for a further period do damage or case any issues with the battery. I assume the car's radio's/controls/a/c runs off the 12 v battery but is recharged back to full power from the cars HV battery.

You can just press the start button on the steering column or the brake pedal to fire it up again.

You can also fasten the seatbelt ‘behind you’, if that makes sense, so between your back and the seat, and as long as you’re sitting in the seat the car will stay powered up.

Thanks for that, I assume though as asked you can't actually run the 12v battery down by doing this for an hour or more as I am assuming the main HV car battery will keep the 12v battery topped up.

Yes, correct, the car is essentially ‘on’, so the DC to DC converter will be working to keep the 12v battery topped up.

Tesla Bjorn did one of his camping trips in an ID, kept the car live all night by the seatbelt being clicked in and a dumbbell on the seat. He used it to keep the cabin warm.

Not necessarily if the car is witched off. If you leave the car in "Drive" it will probably use the traction battery and that might be the best solution to avoid running down the 12 volt (assuming there is no reason why this should not be done in an ID4). I assume the ID4 does not have a utility mode? In the Kia e-Niro the car can be switched to utility mode which then runs all the electrics from the traction battery and charges the 12 volt. Ideal for your situation.

The car doesn’t need to be in Drive to charge the 12v, just live via the start button or a press of the brake pedal with some weight on the seat.

Second this as an ID.4 owner.

Note if sitting in the car without HV on as described above and you want air-conditioning, you can press the "stationary air conditioning " button for another 30 minutes of A/C. You get two or three goes at this before the car refuses to do it more to prevent running down the 12V battery. The procedure described above by Tooks is the way forward if sitting in it for ages.
