AdBlue Tank Psa Opel 1.5 2.0 Diesel

Error Codes:
P20E8 - AdBlue pressure too low

Original AdBlue tank with OE code 9816290480used on Opel models derived from platforms with PSA technology and diesel engines with SCR system. The group integrates a plastic tank body, an electric pumping module with pressure sensor, internal level and temperature sensors, anti-freeze heating resistors, and quick connectors to the SCR dosing line. It ensures the storage, conditioning, and controlled delivery of urea solution to the DeNOx catalyst.
Technical characteristics

• HDPE tank resistant to urea, salinityà and thermal cycles, with dedicated mounting points for the floor/chassis.
• Pump module 12 V integrated with pressure sensor and non-return valve.
• Internal level and temperature sensors for managing cold strategies and dosing.
• Heating elements of the tank/line to prevent freezing and crystallization.
• Integrated suction filter and purging/return circuit to limit deposits.
• Waterproof wiring with multipole connector for power supplies and signals (pump, heaters, sensors).
• Quick connectors with O-ring specific for AdBlue and sealed cable pass-through.

DIPA has a range of original and aftermarket quality spare partsà equivalent, as well as refurbished components with functionalityà equal to new.

Functionalityà

• Storage and thermal conditioning of the urea solution 32,5%.
• Pressurization and supply of the SCR dosing unit according to the ECU DeNOx/motor commands.
• Automatic purging of the line when the engine is off to reduce crystal formation.
• Continuous monitoring of level and temperature to optimize catalytic efficiency and cold start.
• Support for diagnostic procedures after refill/replacement (filling registration, actuator tests, and bleeding).

Model applications

Opel

• Vivaro (Bus, Van, Chassis cab)

Citroen

• Jumpy Bus

Peugeot

• Expert (Bus, Van, Chassis cab)

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

Typical defects

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

Any associated DTC codes

• P20E8 – Insufficient reducing pressure/urea.

Final conclusions

The AdBlue tank Opel 9816290480 è a critical component for the’efficiency of the SCR on Opel models derived from PSA. In the presence of warning lights or codes related to pressure, heating, or sensors, the’correct approach involves targeted diagnostics, purging/cleaning of the line, checking the’SCR injector and, if necessary, replacing the tank.

DIPA offers a wide range of spare parts: from original ones to aftermarket selected from the best manufacturers on the market. Not only that: it offers refurbished components with performance equal to new, which allows for savings in replacement and contributes to the protection of the’environment thanks to the’circular economy. If the spare part that suits you is not è available, don't worry: DIPA canò revise “on demand” your part, restoring its full functionalityà and safety in a short time.
