Fitment (Market-Validated Usage)

Based on OEM cross-reference catalogs, Continental SNS955 documentation, and multiple verified aftermarket listings, this NOx sensor is used in Renault–Dacia diesel SCR (AdBlue) systems, mainly on 1.5 Blue dCi Euro 6 passenger car platforms.

Common system applications include:

• Renault Captur II 1.5 Blue dCi
• Renault Clio V 1.5 Blue dCi
• Renault Megane IV 1.5 Blue dCi (selected SCR variants)
• Dacia Duster II 1.5 Blue dCi
• Dacia Sandero III / Logan II Blue dCi (market-dependent)
• Renault–Dacia shared K9K Blue dCi SCR systems

Fitment is strictly based on OE number matching:
227902608R / SNS955 / A2C19306200-03

OE cross-reference data confirms this is a Continental/VDO SNS955 NOx sensor widely used across Renault Group 1.5 Blue dCi SCR architectures.

Aftermarket catalog listings consistently map this OE number to Captur II / Clio V / Duster II SCR applications with the same sensor 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 CAN communication and continuous emissions monitoring.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning

• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 227902608R
• SNS955
• A2C19306200-03 / A2C1930620003
• Continental / VDO SNS955 family

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (608R / 342R / 461R variants) can change calibration, connector type, or ECU pairing.

Why are multiple Renault and Dacia models listed?

Because Renault Group uses the same 1.5 Blue dCi SCR architecture across Captur, Clio, Megane, Duster, and related platforms.

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.
