Compatible with Jaguar Land Rover diesel emission aftertreatment systems using OEM references:

• LR146856
• GX73-5H310-AE
• GX73-5H310-AA / AD (closely related revisions in same sensor family)
• 0281008520
• 0281008521
• Bosch PM2.1 sensor platform (Euro 6d systems)

Typical applications include:

• Land Rover Discovery 5 2.0 / 3.0 Ingenium diesel (MHEV)
• Range Rover Sport L494 facelift diesel variants
• Range Rover Velar diesel platforms (regional configurations)
• Jaguar E-Pace / F-Pace diesel (late Ingenium systems)
• Jaguar XE / XF 2.0d / 3.0d diesel (Euro 6d variants)

Function:
Installed after the diesel particulate filter (DPF), this sensor continuously measures soot concentration in the exhaust stream. The ECU uses this signal to:

• verify DPF regeneration efficiency
• detect soot slip or abnormal emissions
• optimize regeneration strategy
• maintain Euro 6d emissions compliance and diagnostics accuracy

⚠️ Important
This is a PM2.1 particulate matter sensor, not a NOx or pressure sensor. It directly measures soot concentration downstream of the DPF and is critical for modern JLR Ingenium diesel emission control systems.

Fitment must always be confirmed strictly by OEM number (LR146856), as Jaguar Land Rover frequently updates sensor revisions (AA → AE) across model years and ECU calibration levels.
