P2585Fuel Additive Control Module Warning Lamp Request

⚙️ Powertrain (Motor y Transmisión)
Baja

The fuel additive control module asks for the additive-low warning lamp to be illuminated — the additive tank (Eolys/Cerine, used to lower DPF regen temperature) is approaching empty or has reached a service threshold. Continued driving without refilling will eventually disable DPF regeneration.
