Bosch 13628582024 Diesel Particulate Matter Sensor (DPF Sensor)

The Bosch 13628582024 Diesel Particulate Matter (PM) Sensor is a direct-fit OEM-grade sensor engineered to continuously monitor the function of the diesel particulate filter (DPF). By providing precise, real-time soot concentration measurements from the exhaust system, this sensor ensures the DPF is operating correctly and helps reduce particulate emissions by up to 99%.

Unlike older differential pressure sensors that rely on indirect estimates, this Bosch particulate matter sensor performs direct measurement of soot levels. Its operation is based on resistance measurement: soot particles deposit on an internal electrode structure, forming conductive trails between electrodes. The sensor element is regenerated through heating before each measurement cycle to ensure a clean baseline reading. The DPF diagnostic software then evaluates filter condition based on the resulting measured current.

Key Features:

• Direct-replacement OEM particulate matter (PM) sensor — also known as a diesel particulate sensor or DPF soot sensor
• Bosch OEM part number: 0281007682 — BMW OE number: 13628582024
• Supersedes / replaces BMW part number: 13628517454
• Direct-measurement technology for accurate soot concentration readings
• Installs downstream of the diesel particulate filter with a retaining screw mount
• 600mm wiring harness length
• 4-pin connector

Common Diagnostic Trouble Codes (DTCs) associated with a failed particulate matter sensor include: P2002, P242F, and P2453. Symptoms of a failing sensor may include an illuminated check engine or emissions warning light, poor engine performance, increased visible exhaust emissions, or a failed emissions inspection.

Bosch is the original inventor of the automotive particulate matter sensor and continues to supply OEM sensors to vehicle manufacturers worldwide. This part is supplied as a single sensor assembly.
