There is a core deposit for this part.

The DAF AdBlue Pump 1409391 is a critical component in the Selective Catalytic Reduction (SCR) system of many DAF trucks. Also known by cross-reference numbers like 1705244, 5273338, 4931694, and others, this urea dosing pump module (often called the AdBlue dosing unit or feed module) ensures precise injection of AdBlue (DEF – Diesel Exhaust Fluid) into the exhaust stream to reduce harmful NOx emissions.

Designed primarily for Euro 5 and some Euro 6 applications, the 1409391 pump is commonly fitted to popular DAF models such as:

• DAF LF45
• DAF LF55
• DAF CF65
• Certain DAF CF and LF series trucks with Cummins or PACCAR engines

This air-assisted urea pump (sometimes linked to Emitec/Grundfos or Bosch-style technology in aftermarket references) delivers reliable performance in demanding commercial transport conditions.

Why the DAF 1409391 AdBlue Pump Matters

Modern diesel trucks must comply with strict emission regulations. The AdBlue system, powered by this dosing pump, converts nitrogen oxides into harmless nitrogen and water. When the pump fails, common symptoms include:

• Check engine light or SCR fault codes
• Reduced engine power (limp mode)
• Increased fuel consumption
• AdBlue warning messages on the dashboard
• Potential MOT/roadworthiness test failure

Replacing a faulty unit with a quality DAF AdBlue Pump 1409391 restores full emissions compliance, engine performance, and operational efficiency.

Key Features and Benefits

• Precise dosing – Accurate AdBlue delivery for optimal SCR efficiency
• Durable construction – Built to withstand vibration, temperature extremes, and long-distance haulage
• Direct compatibility – Plug-and-play replacement for OE part 1409391 and equivalents (1705244, 5273338, etc.)
• 24V operation – Matches standard truck electrical systems
• Improved reliability – Reduces risk of crystallization or blockages in the dosing line

Common Signs Your DAF AdBlue Pump Needs Replacement

1. Persistent AdBlue system faults or error codes related to dosing pressure/temperature
2. Pump noise (whining or unusual operation)
3. Crystallized AdBlue around connections
4. Vehicle derating or speed limiter activation
5. Failed emissions test results

Addressing these early with a replacement 1409391 dosing module avoids downtime and costly towing.

Investing in a reliable DAF AdBlue Pump 1409391 keeps your truck compliant, efficient, and on the road longer. If you’re experiencing SCR issues or planning preventive maintenance, sourcing this essential urea pump module is one of the smartest decisions for fleet operators and independent drivers alike.
