• For a 2021 Volkswagen ID.4, start with the basics: ensure the charging plug and charge port are secure and undamaged.
• Check the 12V accessory battery condition—many EV warning lights are triggered by low 12V voltage or accessory faults.
• Look for any obvious alerts on the instrument cluster or infotainment system that indicate battery temperature or charging issues.
