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

Based on OEM Hyundai/Kia EPC listings and multiple verified aftermarket catalogs, part number 29650-2U010 is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi diesel platforms (C-segment cars and compact SUVs).

Common system applications include:

• Kia Ceed III (CD) 1.6 CRDi Euro 6 SCR
• Hyundai i30 (PD) 1.6 CRDi Euro 6 SCR
• Kia XCeed / Proceed 1.6 CRDi (selected SCR variants)
• Hyundai Kona 1.6 CRDi (Euro 6 diesel SCR variants)

Fitment is strictly based on OE number matching:
29650-2U010

OE cross-reference listings confirm this NOx sensor is used on Hyundai/Kia 1.6 CRDi SCR systems and is commonly paired with Continental SNS0825A / related SNS08xx sensor architecture depending on revision.

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 sensor operates under high exhaust temperatures and continuously monitors emissions efficiency for SCR dosing control and catalyst performance.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication faults
• P2200 / P220E / P229F type codes (platform dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 29650-2U010
• SNS0825A (common aftermarket cross-reference)
• A2C17250800-01
• Hyundai/Kia SCR NOx sensor family (1.6 CRDi platforms)

FAQ

Is this sensor vehicle-specific?

Yes. Hyundai/Kia NOx sensors are ECU-calibrated. Even similar numbers (2U010 / 2U100 / 2U150) can differ in connector, software mapping, or exhaust position.

Why do Ceed, i30, and Kona appear together?

Because they share 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.
