Fitment Level: OE Match / Platform Verified

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

• 8K0906261C
• 8K0906261A / 8K0906261D (same sensor family revisions)
• 0281006842
• 0281006843
• 0281008081 (later revision cross-family in some catalog systems)
• 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 (CKVC / CAPA engine families)
• Audi A4 Allroad B8 3.0 TDI quattro
• Audi A5 8T 3.0 TDI quattro
• Audi A5 Sportback 3.0 TDI quattro
• Selected EA897 V6 TDI Euro 5 / early Euro 6 diesel configurations

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 manage regeneration cycles, evaluate filter efficiency, 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 (8K0906261C), as Audi B8 3.0 TDI platforms use multiple Bosch revisions across model years.
