VOE21870667 — Dosing Module Voe21534115 Voe21870667 For Volvo D11 D13 D16 Mack Mp7 Mp8 Engine

This dosing module is a key component of the selective catalytic reduction (SCR) system, responsible for precisely injecting diesel exhaust fluid (DEF) into the exhaust stream to reduce emissions. Manufactured to meet stringent Volvo and Mack emission control standards, it ensures accurate DEF delivery for optimal catalyst performance. Operators may observe reduced engine power, increased exhaust emissions, or diagnostic trouble codes related to the SCR system if this module is not functioning correctly.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing dosing module can be a 'check engine' light or a specific SCR system fault code appearing on the dashboard. If ignored, the system may enter a reduced power mode, and exhaust emissions will increase. Continued operation with a faulty dosing module will eventually lead to non-compliance with emissions regulations and potential engine shutdown.

Installation Tip

Ensure the DEF tank is clean and free of any contaminants before installing the new dosing module. Avoid overtightening the module's mounting bolts, as this can damage the sealing surface.

Service Note

Inspect the DEF lines, filter, and tank for any signs of crystallization or contamination when replacing the dosing module.
