Compatible with Mercedes-Benz diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references A0009058402 / 0009058402 / 0281006352 / 0281006353 / A0009058403 in diesel aftertreatment (DPF system). (buymachineryparts.com)

Typical applications include:

• Mercedes-Benz GLK250 Bluetec (X204 platform)
• Mercedes-Benz GLK220 CDI / GLK200 CDI variants (OM651 diesel engines)
• Mercedes-Benz R-Class W251 / V251 diesel models (selected variants)
• Mercedes-Benz ML / GL platform derivatives using OM651-based configurations
• Vehicles equipped with diesel particulate filter (DPF) soot monitoring system for regeneration feedback

⚠️ Note: This is a post-DPF particulate matter (soot) sensor, not a NOx sensor or exhaust pressure sensor. It measures soot concentration after the diesel particulate filter to monitor efficiency and support regeneration control.

Function: Installed downstream of the DPF in the exhaust system, the sensor continuously measures particulate emissions and sends real-time data to the ECU. This helps optimize regeneration cycles, detect filter blockage early, and maintain emissions compliance.
