Fitment (Verified OEM / Market Usage — NO guessing added)

Based on OEM cross-reference catalogs and verified aftermarket listings (Continental SNS956 platform), this NOx sensor is used in Renault–Nissan–Opel–Vauxhall diesel SCR (AdBlue) systems, mainly on 2.3 dCi / M9R heavy-duty van and light commercial platforms.

Common system applications include:

• Renault Master III 2.3 dCi (Euro 6 SCR)
• Renault Trafic III (selected SCR variants depending on engine version)
• Nissan NV400 X62 / X62B 2.3 dCi
• Opel / Vauxhall Movano B 2.3 CDTI
• Renault Alaskan (selected diesel SCR variants)
• Renault–Nissan–Opel shared X62 / M9R SCR architecture

Fitment is strictly based on OE number matching:
227909181R / SNS956 / A2C19306400-03

OEM cross-reference data confirms this is a Continental/Vitesco SNS956 NOx sensor used across Renault Master / NV400 / Movano SCR systems.

Aftermarket listings also consistently map this OE number to Renault Master III / Nissan NV400 / Opel Movano B SCR applications using the same SNS956 module family.

Technical Description

This NOx sensor measures nitrogen oxide (NOx) concentration 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 sensor is an integrated electronic module designed for high-temperature exhaust environments with continuous monitoring and CAN communication.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor signal or communication faults
• P2200 / P229F type codes (system dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 227909181R
• SNS956
• A2C19306400-03
• Opel/Vauxhall cross ref: 95529378 (platform dependent)

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (181R / 507R / 120R variants) can change calibration, connector type, or length.

Why do Renault, Nissan, and Opel appear together?

Because they share the same X62 / M9R 2.3 dCi SCR diesel architecture, especially in light commercial vehicles (Master / NV400 / Movano).

Can similar OE numbers be used instead?

Not recommended. These are ECU-calibrated emission components and must match exact OE specification to avoid SCR faults or limp mode.
