Techinical Info

The AdBlue pump DAF code OE 044404229Z is a urea/SCR dosing module (BOSCH) for heavy-duty DAF Euro 6 vehicles. It is a complete unit of the Denoxtronic 2.2 24 V type, which integrates in a single housing the hydraulic section for AdBlue management (suction, filtration, pressurization, delivery), the main sensors and the control electronics.

The module is responsible for taking the urea solution from the tank, pressurizing it and sending it to the SCR injector mounted on the exhaust line, ensuring the correct dosing of AdBlue required for selective catalytic reduction of NOx and compliance with the Euro 6 regulation for heavy diesel engines.

Technical specifications

  • Type: AdBlue dosing pump for SCR system
  • System: Denoxtronic 2.2 family for commercial vehicles
  • Supply voltage: 24 V DC
  • Application: Euro 6 exhaust aftertreatment systems with SCR catalyst
  • Integrated functions: suction, filtration, pressurization, pressure control and delivery of AdBlue to the injector

DIPA can intervene to overhaul these components thanks to its experience and expertise.

Functions

  • Withdrawal of AdBlue from the tank via suction line and dedicated filter
  • Pressurization of the fluid in the delivery circuit toward the SCR injector, via electric motor and integrated pumping unit
  • Measurement and regulation of AdBlue pressure via internal sensor and closed-loop control by the module electronics
  • Precise dosing of the AdBlue quantity based on engine load, air mass, temperature and signals from NOx sensors upstream and downstream of the catalyst
  • Management of filling and purging phases of the circuit to reduce the risk of urea crystallization in the pipes during downtime or low temperatures
  • Self-diagnostic functions on pump motor, pressure sensor, internal valves and power supply, with fault reporting to the engine/SCR control unit
  • Communication with the engine ECU and SCR controller via the vehicle network, exchanging operating parameters and fault codes

Model applications

  • DAF XF Euro 6 (road tractors with MX engines)

Common faults

  • Pump electric motor failure
  • AdBlue crystallization inside internal passages and pipes
  • Warning light illumination on the instrument panel

Final conclusions

The AdBlue pump DAF OE 044404229Z is a critical component for the correct operation of the SCR system on DAF Euro 6 vehicles, particularly on the XF range.
