AdBlue Tank Rifter Berlingo 1.5 HDi

Error Codes:
P20E8 - AdBlue pressure too low

Original PSA AdBlue tank with OE code 9832421480, intended for SCR systems of BlueHDi engines. The unit integrates a tank body made of plastic material, an electric pump module, internal level and temperature sensors, anti-freeze heating elements, and quick connectors towards the SCR dosing line. It guarantees storage, conditioning, and controlled delivery of the urea solution to the DeNOx catalyst.

Technical features

• Tank made of HDPE resistant to urea, salinity, and thermal shocks, with dedicated mounting points for the chassis/plate.
• Integrated 12 V pump module with pressure sensor and non-return valve.
• Internal level and temperature sensors for managing cold strategies and dosing.
• Heating elements for the tank/line to prevent freezing and crystallization.
• Integrated pickup filter and purge/return circuit to reduce deposits.
• Watertight wiring with multi-pin connector for power supplies and signals.
• Quick connectors with specific O-rings for AdBlue and sealed cable pass-through.

DIPA can intervene to also overhaul this important component for the correct functioning of the engine.

Functions

• Storage and thermal conditioning of the 32.5% urea solution.
• Pressurization and supply of the SCR doser according to ECU DeNOx/engine commands.
• Automatic purging of the line when the engine is off to limit crystal formation.
• Continuous monitoring of level and temperature to optimize catalytic efficiency and cold start.
• Support for diagnostic procedures after refilling or replacement (recording filling, actuator testing, and purging).

Model applications

Citroën

• Berlingo
• Berlingo (Box/Limousine)

Peugeot

• Rifter

DIPA recommends always verify the compatibility of the spare part before purchase.

Typical faults

• Reduced urea circuit pressure due to pump wear, clogged filter, or micro-leaks → SCR warning lights and performance limitations.
• Tank/line heater failure → fluid freezing and delayed activation at low temperatures.
• Level/temperature sensor anomalies → incorrect “UREA” indications and degraded strategies.
• Crystallization in the tank/lines or clogged SCR injector → insufficient dosing and catalyst efficiency errors.
• Oxidation/infiltrations on cable pass-through or connectors → electrical interruptions/intermittencies.
• Mechanical damage to the shell (impacts/rubbing) → leaks and ammonia smell.

Associated DTC codes

• P20E8 – Insufficient reducing/urea pressure.

Final conclusions

The PSA AdBlue tank 9832421480 is a critical component of the SCR system on latest-generation BlueHDi vehicles. In the presence of warning lights or DTCs related to pressure, heating, or sensors, the correct intervention involves targeted diagnosis, line purging/cleaning, verification of the SCR injector, and, if necessary, regeneration or replacement of the assembly.
