A0009004810 / A0009019603 / 0281033318 Mercedes Benz AdBlue Control Module ECU.

Product Description

This is an OEM Mercedes-Benz AdBlue Control Module (ECU), used to monitor and precisely regulate the AdBlue injection process in BlueTEC diesel engines. It ensures optimal NOₓ reduction performance through the Selective Catalytic Reduction (SCR) system. The module is typically located near the AdBlue tank and communicates with the vehicle’s main ECU to control dosing and diagnostics.

When functioning correctly, it helps vehicles stay compliant with emissions regulations, maintains fuel efficiency, and prevents warning lights. In many cases, this module can be replaced directly (bolt-on replacement), though programming may be required.
