Compatible with BMW diesel vehicles equipped with exhaust particulate (PM) sensor systems using OEM references 9887657-01 / 9887657 / 13629887657 / 0281008329 / 0281008330 in diesel aftertreatment (DPF system).

Typical applications include:

• BMW X5 G05 (2018–2024) diesel variants (30d / 40d / M50d depending on market)
• BMW X6 G06 (2019–2024) diesel variants
• BMW X7 G07 (2019–2024) diesel variants
• BMW B57 diesel engine family equipped with DPF soot monitoring system
• BMW diesel SUVs using post-DPF particulate matter sensing for regeneration control

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

Function: Installed in the exhaust aftertreatment system downstream of the diesel particulate filter (DPF), the sensor continuously measures soot concentration and sends data to the ECU to optimize regeneration cycles, protect the DPF, and maintain emissions compliance.
