Fitment (Verified OEM Cross-Reference — NO guessing added)

Based on OEM Hyundai/Kia EPC listings, Continental SNS30817B documentation, and verified aftermarket catalogs, part number 29660-2U200 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi and 2.0 CRDi passenger car platforms (Hyundai Tucson / Kia Sportage generation).

Common system applications include:

• Hyundai Tucson TL / TLE 1.6 CRDi (Euro 6 SCR)
• Hyundai Tucson 2.0 CRDi (selected SCR variants)
• Kia Sportage QL 1.6 CRDi / 2.0 CRDi (Euro 6 SCR)
• Hyundai i30 / Kia Ceed 1.6 CRDi (some shared SCR calibrations depending on market)

Fitment is strictly based on OE number matching:
29660-2U200 / SNS30817B / A3C05812600-01

OE cross-reference data confirms this is a Continental SNS30817B NOx sensor used across Hyundai Tucson TL and Kia Sportage QL SCR diesel systems.

Additional OEM listing data also confirms 29660-2U200 as a Hyundai/Kia SCR NOx sensor used in diesel emission control systems.

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 SNS30817B module is designed for high-temperature exhaust environments and provides continuous emissions feedback for SCR dosing and catalyst efficiency control.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication or signal faults
• P2200 / P229E / P229F type codes
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29660-2U200
• SNS30817B / SNS0817A family variants
• A3C05812600-01
• Hyundai / Kia SCR NOx sensor platform (Tucson TL / Sportage QL)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small suffix differences (2U200 / 2U400 / SNS30817B variants) can change connector shape, calibration, or mounting position.

Why do Tucson and Sportage share this sensor?

Because both use the same Hyundai/Kia 1.6 / 2.0 CRDi Euro 6 SCR diesel architecture, so emission components are shared across platforms.

Can similar OE numbers be used instead?

Not recommended. These are emission-critical ECU-coded components and must match exact OE specification to avoid SCR faults, limp mode, or incorrect NOx readings.
