Cerina Pump Citroen Peugeot Diesel

The cerium pump with OE code 1525LK è is a component used in the exhaust gas after-treatment system of diesel engines equipped with a particulate filter (FAP). This device è is responsible for transferring the’additive (cerium or Eolys) from the tank to the injection circuit in the exhaust manifold. Its function è is essential to ensure the effectiveness of the FAP filter regeneration, reducing the accumulation of particulate over time.

Technical characteristics

The module with code 1525LK è a pump integrated into the tank of the’FAP additiveand è designed to operate at low pressure. The pump è is driven by the engine control unit via an electric command and operates in pulses during fuel refueling phases.

Main features:

• Power supply: 12 Volts
• Operating pressure: low pressure (indicative <1 bar)
• Supported additive type: Eolys 176, PowerFlex or equivalent depending on vehicle
• Pump body material: reinforced plastic
• Connection: multipole connector + rigid or flexible line to the’system
• Installation: integrated into the additive tank, under the rear body of the vehicle

DIPA has a range of original and aftermarket quality spare partsà equivalent.

Functionalityà

This pump activates during fuel refueling when the sensor detects the’opening of the diesel tank flap. At that moment, the control unit commands the pump to inject a specificà amount of additive into the circuit, in proportion to the liters of diesel dispensed. The’additive facilitates the combustion of the particulate accumulated in the particulate filter, lowering the temperature required for regeneration.

Once installed, the pump must be adapted using diagnostic tools to be recognized by the vehicle's FAP control unit, and to reset the additive level after replacement.

Defects and causes

The mostù common defects found in the 1525LK wax pump are:

• Electrical failure of the pump motor : no activation upon command from the control unit
• Clogging of the duct : crystallization of the’ additive in the pipes or in the pump
• CAN communication error : in case of interruption or malfunction of the module
• False additive levels : if the pump fails to transfer the’ additive correctly, the level sensor mayò provide incorrect data
• Leaksdue to worn seals or cracks in the plastic body
• Installation errorreplacement without correct coding or reset of the additive counter

Final conclusions

The OE 1525LK cerina pump è an essential component for the proper functioning of the particulate filter in diesel vehicles of the PSA group. Its failure compromises the automatic regeneration of the DPF and canò lead to serious damage to the exhaust system.
