New Cerina Tank Citroen Peugeot

The tank with original OE code 9672419980 is a component used in the exhaust gas after-treatment system of diesel vehicles from the PSA group. It contains the additive Cerina, necessary for the proper functioning of the particulate filter (FAP). The module consists of a high-strength plastic container, inside which an electric pump is integrated for the distribution of the additive into the fuel tank. The system is electronically controlled by the engine control unit and works in synergy with the level sensor and the FAP module.

2. Technical characteristics

• Structure: body made of high chemical resistance composite plastic
• Tank capacity: variable depending on the application (generally 1–2 liters)
• System: integrated electric pump, multi-way wiring, level sensor
• Electric power supply: 12 V, control from engine ECU
• Mounting: usually fixed near the fuel tank, under the vehicle floor
• Compatible additive: Eolys Powerflex or specific Cerina, based on vehicle approval

3. Functionality

The Cerina tank is responsible for containing and dosing the additive necessary for the regeneration of the particulate filter (FAP). At each refueling, the control unit calculates an amount of additive to inject into the diesel tank. Cerina lowers the combustion temperature of the particulate in the filter, allowing regeneration even at lower temperatures.

5. Defects and causes

Malfunction of the pump

The integrated pump can fail due to wear or electrical malfunctions, preventing the delivery of the additive into the diesel tank. This results in the inability to regenerate the FAP filter.

Faulty level sensor

A defective level sensor can transmit incorrect readings to the control unit, causing false alarms or stopping the additive system even with a full tank.

Leak or breakage of the tank

Over time, the plastic material can crack or deform, especially in the presence of impacts or external corrosion, causing additive leaks.

Damaged or oxidized connectors

Problems with the electrical connections of the module can interfere with the operation of the pump or sensor, generating errors in the control unit.

Failure to program after replacement

After replacing the tank, it is necessary to perform a learning procedure via diagnostics. The absence of this procedure prevents the proper functioning of the new module.

Final conclusions

The Cerina tank OE 9672419980 is a fundamental element for the proper functioning of the FAP system in PSA diesel vehicles. Its role in managing the additive is crucial for maintaining the efficiency of the particulate filter and preventing early clogging.
