Bosch 0281008516 Particulate Matter Sensor for Diesel Particulate Filter DPF

The Bosch 0281008516 is an OEM-quality Particulate Matter (PM) Sensor designed to continuously monitor the performance of the Diesel Particulate Filter (DPF). This sensor provides direct measurement of soot concentration in the exhaust stream, delivering accurate, real-time data to the engine control unit to help ensure emissions compliance and optimal drivetrain performance.

How It Works:

The particulate matter sensor operates on the principle of resistance measurement. Soot particles are deposited onto an internal electrode structure, forming conductive trails between the electrodes. Before each measurement cycle, the sensor element is regenerated via internal heating to establish a clean baseline. The DPF diagnostic software then evaluates DPF function using the resulting current readings — enabling precise detection of DPF degradation or failure.

Key Features:

• Directly measures soot concentration downstream of the diesel particulate filter
• Self-regenerating sensor element ensures measurement accuracy over time
• Enables DPF diagnostic software to assess filter health and functionality
• OEM-equivalent fitment — direct replacement for Land Rover OE part numbers LR146853, C2D57277, LR114277, and C2D60729
• Manufactured by Bosch, the world's largest supplier of automotive components
• Designed for diesel-powered passenger cars and light commercial vehicles

Replace your particulate matter sensor at the same time as a DPF replacement, or when a check engine light indicates sensor fault, to maintain accurate emissions monitoring and avoid unnecessary DPF-related fault codes.
