Cerium Tank Peugeot 1.6 2.0 HDi

The cerine tank with OE code 1606340280 is a component of the exhaust gas aftertreatment system used in PSA Group diesel engines. It is a compact unit that integrates the cerine additive tank, a dosing pump and a control unit. The main function of this component is to ensure the controlled injection of the additive into the exhaust system to facilitate the regeneration of the particulate filter (FAP/DPF), reducing emissions and improving the efficiency of the soot particle combustion process.

Technical specifications

The tank is made of plastic material highly resistant to chemical and thermal agents and has a modular structure. It contains inside:

• an integrated low-pressure electric pump,
• a management electronic module (control unit),
• a hydraulic circuit for transferring the cerine additive from the tank to the dosing point.

• Average tank capacity: approximately 1.5–2 liters
• Pump power supply: 12 V
• Location: lower rear part of the vehicle, near the fuel tank
• Vehicle connection: dedicated electrical and hydraulic connections, specific wiring
• Supported additive: cerine (e.g. Eolys DPX42, 176, 179) – not compatible with AdBlue

DIPA offers a range of original and equivalent-quality aftermarket spare parts.

Functionality

During engine operation, the engine control unit commands the activation of the pump and the dosing of cerine into the fuel tank or directly into the exhaust, depending on the system type. The goal is to lower the combustion temperature of the soot in the particulate filter, allowing regeneration even in urban conditions or under low load. The system records each regeneration cycle and tracks the remaining additive level, issuing a warning in case of depletion or malfunction.

Defects and causes

The most common problems encountered with the cerine tank OE 1606340280 are related to electronic malfunctions, mechanical wear or system contamination. The most frequent defects include:

• Internal pump failure: caused by wear, residue buildup or dry running if the tank is empty.
• Malfunction of the integrated control unit: loss of communication with the engine ECU or data transmission errors.
• Leaks or cracks in the tank body: cause additive leaks and corrosion formation in the rear area of the vehicle.
• Inaccurate or stuck level sensor: may cause a false low-additive level warning.
• Error in the replacement or refilling procedure: failure to reset the additive counter can generate persistent error codes and block DPF regeneration.

The main causes are attributable to refilling with non-compliant products, lack of maintenance, or errors during installation or coding.

Final conclusions

The cerine tank with OE code 1606340280 is an essential component for the correct operation of the DPF system in PSA Euro 5 diesel engines. Its malfunction can compromise particulate filter regeneration, increase emissions and cause engine warning lights to illuminate.
