Compatible with BMW diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references 8582023-01 / 8582023-03 / 13628582023 / 0281006636 / 0281006662 / 0281006636 / 0281006662 in diesel aftertreatment (DPF system).

Typical applications include:

• BMW 1 Series F20 / F21 diesel (116d / 118d / 120d)
• BMW 2 Series F22 / F23 diesel models
• BMW 3 Series F30 / F31 / F34 / F36 diesel (316d / 318d / 320d / 330d depending on engine)
• BMW 4 Series F32 / F33 / F36 diesel variants
• BMW X1 F48 diesel (selected configurations)
• BMW diesel engines using N47 / B47 / N57 engine families with DPF soot monitoring system
• Vehicles equipped with diesel particulate filter (DPF) regeneration feedback and particulate matter sensing system

⚠️ Note: This is a post-DPF soot concentration sensor, not a NOx sensor or differential pressure sensor. It measures particulate output after the DPF to help the ECU control regeneration and monitor filter efficiency.

Function: Installed in the exhaust aftertreatment system downstream of the diesel particulate filter (DPF), this sensor provides real-time soot concentration data to improve regeneration accuracy, reduce DPF clogging risk, and ensure emissions compliance.
