Fitment Level: OE Match / Platform Verified

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

• 95860626123
• 0281006648
• 95860626121 (closely related variant in same sensor family)
• Bosch 0 281 006 648 / 0 281 008 077 (same PM sensor family used across VAG platforms)

Typical applications include Porsche diesel platforms such as:

• Porsche Cayenne 958 3.0 TDI diesel (2011–2017)
• Porsche Cayenne S Diesel (selected variants)
• Porsche Panamera 970 3.0 TDI diesel (selected configurations)
• VW Touareg 7P 3.0 TDI diesel (platform-shared system)
• Audi Q7 4L / 4M 3.0 TDI diesel (platform-dependent variants)

This sensor is used in diesel particulate matter (PM) monitoring systems, where it measures soot concentration downstream of the diesel particulate filter (DPF). The ECU uses this signal to control regeneration cycles, evaluate DPF efficiency, and detect abnormal soot loading in VAG/Porsche diesel emission systems.

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

Fitment must always be confirmed strictly by OEM number (95860626123 / 0281006648), as Porsche and VW Touareg share multiple revisions across the 3.0 TDI platform.
