Fuel Additive Control Module Requested MIL Illumination
Moderate severity
What it means
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.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
