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 (select emissions configurations)
• MLBevo diesel platform DPF monitoring systems

This sensor is used in diesel particulate matter monitoring systems, where it directly measures soot concentration downstream of the diesel particulate filter (DPF). The ECU uses this signal to manage regeneration cycles, evaluate filter efficiency, and detect abnormal particulate slip or DPF degradation.

⚠️ Important:
This is a DPF particulate matter (PM) sensor, not a NOx or pressure sensor.
It directly measures post-DPF soot loading and is essential for regeneration control, emissions monitoring, and diagnostic fault detection.

Fitment must always be confirmed strictly by OEM number (4M0906261C / 0281006715 / 0281006716), as MLBevo diesel platforms use multiple Bosch revisions depending on model year and engine calibration.
