AdBlue tank Psa Jumper Boxer 2.0 d

Error Codes:
P20E8 - AdBlue pressure too low

Original PSA AdBlue tank with OE code 9818716680 installed on light commercial vehicles with BlueHDi engine and SCR system. The’unità integrates a plastic tank body, electric pumping module, level/temperature sensors, anti-freeze heaters, and quick connectors to the dosing line. It manages the storage, conditioning, and delivery of the urea solution to the DeNOx catalyst.
DIPA performs revision and testing of the group (pump, heaters, sensors, and seals) with dedicated functional tests.

Technical characteristics

• HDPE tank resistant to urea and weather agents, with brackets and mounting points to the chassis.
• Pump module 12 V integrated with pressure sensor and purge/return circuit.
• Internal level and temperature sensors for managing dosing and cold strategies.
• Heating elements of the tank/line to prevent freezing and crystallization.
• Integrated suction filter and non-return valve in the module.
• Waterproof wiring and multipole connector for power supplies and signals.
• Quick connectors with O-ring specific for AdBlue.

DIPA può intervene to revise this component as wellì important for the correct functioning of the engine.

Functionalityà

• Storage and thermal conditioning of the urea solution 32,5%.
• Pressurization and supply of the SCR dosing unit according to the ECU DeNOx/engine commands.
• Automatic purge line with the engine off to reduce deposits.
• Continuous monitoring of level/temperature for cold start strategies and SCR efficiency.
• Support for diagnostic procedures post-refill/replacement (filling registration, actuator tests, and purging).

Model applications

Peugeot

• Boxer

Citroën

• Jumper

DIPA recommends to always check compatibilityà of the spare part before’purchase.

Typical defects

• Reduced pressure in the urea circuit due to pump wear, clogged filter or micro-leaks → SCR warning lights and performance limitations.
• Faulty heaters → freezing/delays in activation at low temperatures.
• Abnormal level/temperature sensors → incorrect indications “UREA” and degraded strategies.
• Crystallization in the tank/lines or clogged SCR injector → insufficient dosing and catalyst efficiency errors.
• Oxidation or leaks on the cable pass-through/connectors → electrical interruptions/intermittencies.
• Mechanical damage to the shell (impacts, localized corrosion) → leakages.

Any associated DTC codes

• P20E8 – Insufficient reducing pressure/urea.

Final conclusions

The AdBlue tank PSA 9818716680 è is a key component of the SCR system of the Boxer/Jumper 2.0 BlueHDi. In the presence of warning lights or codes related to pressure, heating, or sensors, the’correct intervention involves targeted diagnosis, purging/cleaning the line, checking the’SCR injector and, if necessary, replacing the unit.
