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

Based on OEM Hyundai/Kia EPC listings and verified aftermarket catalogs, part number 29650-2U150 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi C-segment diesel platforms (Hyundai i30 / Kia Ceed generation).

Common system applications include:

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

Fitment is strictly based on OE number matching:
29650-2U150 / SNS0820A

OE cross-reference listings confirm this sensor is part of the Continental SNS0820A NOx sensor family used across Hyundai/Kia 1.6 CRDi SCR diesel systems, typically as a revised variant within the same platform group as 2U100 / 2U200 sensors.

Additional EPC listings also confirm Hyundai/Kia 29650-2U150 as a direct SCR NOx sensor replacement within the same emission control architecture 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 uses AdBlue (urea solution) to reduce NOx emissions and meet Euro 6 standards.

The SNS0820A 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

• 29650-2U150
• SNS0820A
• Hyundai/Kia 1.6 CRDi SCR NOx sensor family
• 296502U150 (format variant used in aftermarket listings)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even small differences like 2U100 / 2U150 / 2U400 can change connector shape, calibration, or exhaust position.

Why do Ceed and i30 share this sensor?

Because both use the same Hyundai/Kia 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.
