Commonly searched OE numbers fitting DPF Additive Pump from the TecDoc catalogue.
The DPF additive pump injects a cerium-based catalyst (commonly Eolys) into the diesel fuel to lower the soot ignition temperature inside the diesel particulate filter. It draws from a separate tank in the boot or under the vehicle and meters the additive in proportion to refuelling. A failed pump prevents regeneration and triggers a warning chain.
Pump replacement is usually triggered by fault codes or low additive level despite a recently topped-up tank. The pump is a simple electromechanical device with a typical service life of 100,000–150,000 miles (160,000–240,000 km).
Cerium additive systems are mostly used by PSA (Peugeot, Citroën) and some Ford and Mazda diesels. The pump must match the additive type and the tank fitting.
Failure modes are dominated by additive crystallisation and electrical faults.
The additive system feeds the DPF, so faults often spread along the chain.
Yes. "DPF Additive Pump" and "Additive Pump" refer to the same car part. Other common names include Additive Pump. The part is the same regardless of which name is used.
Short journeys are possible, but DPF regeneration will not run correctly and the soot load will increase rapidly. Continued driving leads to forced ECU regeneration cycles and eventually a blocked filter.
Roughly every 60,000–75,000 miles (96,000–120,000 km) on most PSA diesels. The dashboard shows a warning when the level drops below threshold.
Eolys and similar additives are skin and eye irritants. Wear gloves and eye protection when handling them, and clean any spills immediately — they stain bodywork and trim.
