Fuel Additive Control Module Requested MIL Illumination
The fuel additive control module — typical for diesel cars with a separate Eolys/Cerine additive tank that aids DPF regeneration — has requested the ECM to illuminate the MIL because of an emissions-relevant fault on its side. The original fault is in the additive module itself.
