Compatible with VAG diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references 04L0906261B / 0281006271 / 0281006272 / 1275101863 / 127510 in diesel aftertreatment (DPF system).

Typical applications include:

• Audi Q7 3.0 TDI (4L platform diesel variants)
• VW Touareg 3.0 TDI (7L platform diesel variants)
• VAG V6 TDI diesel engines with DPF soot monitoring system
• Vehicles equipped with diesel particulate filter (DPF) regeneration feedback sensor system
• Shared Audi / VW / Porsche diesel aftertreatment configurations

⚠️ Note: This is a post-DPF particulate matter (soot) sensor, not a NOx sensor or exhaust pressure sensor. It measures soot concentration after the diesel particulate filter to monitor efficiency and control regeneration cycles.

Function: Installed downstream of the DPF in the exhaust system, the sensor continuously sends real-time particulate data to the ECU. This helps optimize regeneration strategy, detect DPF clogging early, and maintain emissions compliance.
