Fuel Additive Dpf Filter Tank Pump For Citroen Peugeot Vauxhall Opel 9815712680

Ensure your diesel’s exhaust-aftertreatment system keeps working properly with our “Fuel Additive / DPF Filter Additive Tank & Pump (OE 9815712680)” — a full replacement reservoir and pump assembly designed for select Citroën, Peugeot (and related PSA-group) diesel models that rely on additive-based DPF regeneration. This OEM-spec unit stores and delivers the special additive fluid (Eolys / PAT) your vehicle needs to lower soot-burning temperature and allow proper regeneration of the diesel particulate filter (DPF). If the original tank leaks, the pump fails, or additive levels are lost — fitting this new unit restores proper dosing. That helps avoid emissions faults, protects your DPF from clogging, and ensures engine reliability and compliance with emissions standards.

❓ Frequently Asked Questions (FAQ)

Q: What is a DPF additive tank & pump, and why is it needed?
A: Some diesel vehicles use a “fuel-additive / DPF-additive” system where a special fluid (e.g. Eolys / PAT) is stored in a dedicated tank. The pump draws this additive and injects or doses it into the exhaust or fuel-system as required, helping the diesel particulate filter (DPF) burn off soot at lower temperatures — which is important for proper regeneration especially when driving patterns don’t generate high exhaust heat.

Q: What cars / engines is part 9815712680 compatible with?
A: This part is listed for many Citroën / Peugeot models (and related PSA-group diesels) that use additive-based DPF/DPF-additive systems.Before ordering, you should always check if your engine code and emissions package match the OE part number.

Q: What are common symptoms that indicate the tank or pump is faulty?
A: If the additive tank or pump fails, you may see dashboard warnings related to additive system / DPF fault; the engine may flag a “DPF/Emission system” error; regeneration may fail; you might observe exhaust problems, black smoke, or reduced performance; or the additive warning (or “refill additive” alert) may appear, indicating low or empty additive supply.

Q: Can I replace just the pump, or do I need to replace the whole tank + pump assembly?
A: In most cases — including for 9815712680 — the additive pump is integrated with the tank in a sealed unit. So replacement typically involves changing the complete tank + pump assembly to ensure proper sealing and reliable refuelling of additive.

Q: Will replacing this unit fix DPF-related warnings or regeneration problems?
A: Yes — provided the root cause is the faulty additive tank or pump (and not damage in the DPF itself), installing a correct, functioning tank & pump should restore additive delivery, allow proper soot burn-off during regeneration, and clear related fault or warning messages. Regular maintenance with proper additive levels helps prevent DPF clogging and supports engine health.

Q: Does installation require a workshop or special tools / re-coding?
A: Because additive-based DPF systems are managed by the vehicle’s ECU and rely on correct fluid level readings, many experts recommend that replacement (tank + pump) be done by a qualified technician or authorised service centre — ensuring fluid is refilled properly and system reset or calibration is performed if required.
