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

Based on OEM Hyundai/Kia EPC data and verified aftermarket catalogs, part number 29660-2U100 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi / U-series diesel platforms (modern C-segment vehicles).

Common system applications include:

• Kia Ceed (CD) 1.6 CRDi Euro 6
• Kia Proceed 1.6 CRDi
• Kia XCeed 1.6 CRDi
• Hyundai i30 (PD) 1.6 CRDi
• Hyundai i30 Fastback / Wagon 1.6 CRDi
• Hyundai/Kia shared 1.6 CRDi SCR diesel architecture

Fitment is strictly based on OE number matching:
29660-2U100 / SNS0802A / A2C17245500-04

OE cross-reference listings confirm this sensor is part of the Continental SNS0802A NOx sensor family used across Hyundai/Kia 1.6 CRDi SCR systems.

Additional marketplace EPC references also confirm compatibility with Hyundai i30 / Kia Ceed 1.6 CRDi diesel SCR applications using the same sensor family code.

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 uses AdBlue (urea solution) to reduce NOx emissions and meet Euro 6 standards.

The SNS0802A sensor 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 / P229F / U029D type codes (platform dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29660-2U100
• SNS0802A
• A2C17245500-04
• Hyundai/Kia SCR NOx sensor family (1.6 CRDi platforms)
• 296602U100 (format variant used in catalogs)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small differences (2U100 / 2U400 / SNS0802A variants) can change connector type, calibration, or mounting position.

Why do Ceed and i30 share the same sensor?

Because both use the same 1.6 CRDi Euro 6 SCR diesel platform architecture, so emission components are shared.

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.
