There is a core deposit for this part.

The Scania AdBlue Pump 2655852 is a remanufactured OEM DEF (Diesel Exhaust Fluid) supply module—also known as the AdBlue dosing pump, urea reductant pump, or SCR ammonia supply unit—designed for the Selective Catalytic Reduction (SCR) system in Euro 6 Scania trucks. This critical component precisely meters AdBlue into the exhaust to convert harmful NOx emissions into nitrogen and water, ensuring full emission compliance, optimal fuel efficiency, and reliable performance.

Key Function of the 2655852 AdBlue Pump

The pump draws DEF from the tank, pressurizes it, and delivers it to the injector for effective dosing. It includes integrated heating elements to prevent freezing in cold conditions, pressure and temperature sensors, and durable control valves to resist crystallization and maintain accuracy. When operating correctly, it eliminates emission faults, prevents derate mode, and supports smooth long-distance operations.

Compatible with many Euro 6 Scania models, especially those with Cummins diesel engines (e.g., DC13 series):

• R-series (e.g., R 410, R 450, R 500)
• P-series, G-series, S-series
• L-series (select configurations)
• Other Scania trucks from 2016 onward (P, G, R, S, L families)

Common Failure Indicators

The 2655852 pump is robust but can fail from urea buildup, sensor degradation, electrical faults, or contaminated fluid. Frequent symptoms in high-mileage Euro 6 fleets:

• Dashboard warnings: “AdBlue malfunction,” “SCR fault,” “Emissions defect,” or no-start countdown
• Derate/limp mode with power and speed restrictions
• Fault codes: P20E8 (pressure issues), P204F (SCR efficiency), dosing or pressure errors
• Inconsistent DEF usage or complete system shutdown

These issues lead to downtime, higher fuel consumption, and potential damage to NOx sensors or the SCR catalyst if not fixed promptly.

Reman pumps deliver near-OEM performance and are a cost-effective favorite for fleet operators. Professional installation is recommended for system priming, pressure testing, and ECU adaptation.

Why Choose a Quality 2655852 Replacement?

• Immediate restoration of Euro 6 compliance
• Clear warning lights and removal of power limits
• Protection for downstream components like sensors, injectors, and catalyst
• Dependable efficiency on demanding routes

A faulty AdBlue pump can halt your Scania truck—replace it quickly with a trusted 2655852 to resume clean, powerful, and legal driving.
