Fitment Level: OE Match / Platform Verified

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

• 8K0906261A
• 8K0906261C / 8K0906261D (related revisions in same sensor family)
• 0281006842
• 0281006843
• 0281008081 (alternative Bosch revision used in later catalog updates)
• Bosch PM sensor family: 0 281 006 842 / 0 281 006 843

Typical applications include Audi diesel platforms such as:

• Audi A4 B8 3.0 TDI quattro
• Audi A4 Allroad B8 3.0 TDI
• Audi A5 8T / 8T3 3.0 TDI quattro
• Audi A5 Sportback 3.0 TDI quattro
• Audi A5 Convertible 3.0 TDI quattro
• Selected EA897 V6 TDI configurations (Euro 5 / early Euro 6)

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 evaluate DPF efficiency, manage regeneration cycles, and ensure emissions compliance.

⚠️ 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 (8K0906261A / 0281006842 / 0281006843), as Audi B8 V6 diesel platforms use multiple Bosch revisions across production years.
