Fitment Level: OE Match / Platform Verified

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

• 8K0906261D
• 8K0906261A / 8K0906261C (same sensor family earlier revisions)
• 0281008081
• 0281008082
• 0281006525 / 0281007036 (related Bosch cross-reference in same PM sensor architecture)

Typical applications include Audi diesel platforms such as:

• Audi A4 B8 3.0 TDI quattro (facelift)
• Audi A4 Allroad B8 3.0 TDI quattro
• Audi A5 8T / 8F 3.0 TDI quattro
• Audi A5 Sportback 3.0 TDI quattro
• EA897 V6 TDI diesel engines (Euro 5 / early Euro 6 emission systems)

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 evaluate filter efficiency, manage regeneration cycles, and ensure emissions compliance across V6 diesel configurations.

⚠️ 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 (8K0906261D), as Audi B8 3.0 TDI platforms use multiple Bosch revisions across production years.
