Fitment is strictly based on OE number matching:
9816276480 / Bosch 0281006851 / 0281006852

Verified Cross-Reference (Important)

• OEM listings confirm 9816276480 is a PSA NOx sensor used across 1.5 BlueHDi DV5 SCR diesel systems
• Bosch cross-reference confirms 0281006851 / 0281006852 are the matching sensor part numbers for this PSA application
• Aftermarket catalog data shows usage across Peugeot, Citroën, Opel/Vauxhall and DS Euro 6 SCR platforms

📌 Key point:
This is a PSA DV5 1.5 BlueHDi SCR NOx sensor, ECU-coded and position-specific (inlet/outlet depends on exhaust layout).

Technical Description

This NOx sensor measures nitrogen oxide (NOx) levels in diesel exhaust gases and sends real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system, which injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The Bosch 0281006851/6852 module is commonly used for:

• SCR catalyst inlet or outlet NOx monitoring
• AdBlue dosing control feedback
• Emission efficiency verification

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication fault
• P2200 / P229F / U029E type codes
• Reduced engine power (limp mode)
• Incorrect AdBlue consumption or SCR efficiency errors

OE / Part Numbers

• 9816276480 (PSA original)
• 0281006851 / 0281006852 (Bosch)
• Opel reference: 3647875
• PSA DV5 BlueHDi SCR NOx sensor family

FAQ

Is this sensor interchangeable with other PSA NOx sensors?

No. PSA uses ECU-coded SCR sensors. Even similar DV5 sensors (like 9817839480 or SNS404) are not interchangeable.

Why is this used across Peugeot, Citroën, Opel, and DS?

Because all share the same Stellantis DV5 1.5 BlueHDi diesel SCR platform.

Can aftermarket versions work?

Yes, but only if Bosch calibration matches exactly. Low-quality sensors often cause SCR faults or NOx drift issues.
