Bosch 0444025005 Diesel Exhaust Fluid DEF Metering Module

The Bosch 0444025005 is a precision-engineered Diesel Exhaust Fluid (DEF) metering module designed for selective catalytic reduction (SCR) systems in diesel engines. This critical emissions control component accurately meters and injects DEF into the exhaust stream to reduce harmful nitrogen oxide (NOx) emissions and ensure compliance with modern emissions standards.

Key Features:

• Precision dosing control for optimal DEF injection and NOx reduction
• Engineered to Bosch OE specifications for reliable performance
• Designed for compatibility with SCR aftertreatment systems
• Durable construction to withstand harsh exhaust environments
• Direct replacement metering module for diesel emission systems

This metering module is a genuine Bosch component that plays a vital role in modern diesel emission control systems. It ensures precise delivery of DEF to maintain engine efficiency, reduce emissions, and prevent SCR system fault codes. Also known by Bosch part number 444255.
