Have had my engine light on for a while and am getting only one fault code, a P3000 fault code after scanning; "P3000 - Glow plug indicator lamp". The glow plug light on my cluster is working fine, and as far as I can tell the glow plugs are working fine, car starts fine. Cleared it and it came back. No idea what this could be and I cannot find much info on it online. If anyone has any ideas let me know...

from a generic code explanation-

  • Damaged wiring on the high-voltage control system
  • The high-voltage control system wiring is susceptible to failure
  • There may be low fuel in the system.
So I would start by cleaning and replug battery connects, big fuses on top of the battery, and grounds
