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.
