    An internal hardware issue of the glow plug relays may cause an over-voltage supply to the glow plug(s), damaging the glow plug heating element.

    Improved glow plug relays are now available in production and spare parts. If the DTC(s) are stored in the ECM memory, replace the appropriate glow plug relay and the affected glow plug. Refer to the repair manual group 28 in ElsaWeb.
