Cerium Tank Peugeot 1.6 2.0 HDi

The cerine tank with OE code 1606340280 is a component of the exhaust gas post-treatment 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 combustion efficiency of soot particles.

Technical characteristics

The tank is made of plastic material with high resistance to chemical and thermal agents and features a modular structure. Inside it contains:

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

• Average tank capacity: about 1,5–2 liters
• Pump power supply: 12 V
• Positioning: 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 aftermarket spare parts of equivalent quality.

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 type of system. The goal is to lower the combustion temperature of the soot present in the particulate filter, allowing regeneration even in urban conditions or under low load. The system records each regeneration cycle and keeps track of the remaining additive level, issuing a warning in case of depletion or malfunction.

Defects and causes

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

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

The main causes are attributable to refills 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 FAP system in PSA Euro 5 diesel engines. Its malfunction can compromise the regeneration of the particulate filter, increasing emissions and causing engine warning lights to turn on.
