Fitment Level: OE Match / Platform Verified

Compatible with Volkswagen Group diesel emission aftertreatment systems using OEM references:

• 4M0906261D
• 4M0 906 261 D
• 0281007003
• 0281007004
• Bosch PM sensor family 0 281 007 003 / 0 281 007 004
• MLBevo diesel platform sensors (Q7 / Q8 / Touareg / Bentayga systems)

Typical applications include:

• Audi Q7 4M 3.0 TDI / 4.0 TDI
• Audi Q8 4M 3.0 TDI diesel
• Volkswagen Touareg CR 3.0 TDI
• Bentley Bentayga 4.0 TDI diesel
• EA897 / MLBevo V6 diesel emission systems (Euro 6 variants)

This sensor is used in diesel particulate matter monitoring systems, where it measures soot concentration downstream of the DPF. The ECU uses this signal to:

• control DPF regeneration cycles
• monitor filter efficiency
• detect abnormal soot slip or exhaust leaks
• maintain Euro 6 emissions compliance

⚠️ Important:
This is a DPF particulate matter (PM) sensor, not a NOx or pressure sensor.
It directly measures soot concentration after the DPF and is critical for modern diesel emissions control.

Fitment must always be confirmed strictly by OEM number (4M0906261D), as MLBevo platforms use multiple Bosch revisions depending on engine calibration and model year.
