22452554 | Genuine Volvo® / Mack® AHI Dosing System Module

Description and Purpose:

This Genuine AHI Dosing System Module, Part number: 22452554, is a 12-volt component from Volvo/Mack in new condition. It controls precise fuel injection into the exhaust stream to help reduce soot and support DPF regeneration. Built for trucks running MP7, MP8, D11, and D13 engines, it’s commonly found on Volvo VNL, VNR, and Mack models like Granite and Anthem produced between 2012 and 2018.

Why Replacement is Important:

Overuse, exposure to heat, and soot buildup gradually reduce dosing accuracy. Swapping this module helps restore proper injection timing and keeps your system from falling into fault modes or triggering power restrictions.

Impact on Vehicle Performance:

A stable dosing cycle keeps your engine smooth, supports ideal torque levels, and reduces costly downtime. Maintaining this part means fewer errors, better fuel economy, and longer trips without disruptions.

Manufacturer Information:
