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

Based on OEM Hyundai/Kia EPC listings and verified aftermarket SCR catalog data, part number 29660-2U001 (SNS0827B) is used in Hyundai/Kia Euro 6 diesel SCR (AdBlue) systems, mainly on 1.6 CRDi diesel compact SUV and C-segment platforms (Hyundai Kona / Tucson / Kia Sportage depending on market and SCR position).

Confirmed applications include:

• Hyundai Kona 1.6 CRDi Euro 6 SCR (2017–2020 diesel variants)
• Hyundai Tucson TL / TLE 1.6 CRDi SCR variants
• Kia Sportage QL / QLE 1.6 CRDi SCR variants
• Hyundai/Kia shared 1.6 CRDi SCR diesel architecture

Fitment is strictly based on OE number matching:
29660-2U001 / SNS0827B

Verified Cross-Reference (Important)

• Aftermarket EPC listings confirm 29660-2U001 = SNS0827B NOx sensor used on Hyundai Kona / Tucson / Kia Sportage 1.6 CRDi SCR systems (Euro 6)
• Equivalent listings confirm this sensor is part of the Continental SNS0817/SNS0827 NOx sensor family used on Hyundai/Kia SCR exhaust systems
• Real-world vehicle compatibility listings include Hyundai Kona 2017–2020 diesel SCR applications

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 SNS0827B module is commonly used in post-SCR or system monitoring positions, ensuring catalyst efficiency and correct AdBlue dosing control.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor signal or communication faults
• P2200 / P229F / U029E type codes (platform dependent)
• Limp mode / reduced engine power
• Increased emissions

OE / Part Numbers

• 29660-2U001
• SNS0827B
• A2C17248800-01 (Continental equivalent family)
• Hyundai/Kia 1.6 CRDi SCR NOx sensor family

FAQ

Is this sensor interchangeable with other 2U series sensors?

No. Even within Hyundai/Kia 1.6 CRDi systems, sensors like 2U200 / 2U220 / 2U600 / 2U001 differ in calibration, connector shape, and ECU coding.

Why do Kona, Tucson, and Sportage share this sensor?

Because they all use the same Hyundai/Kia 1.6 CRDi Euro 6 SCR diesel platform architecture, so emission components are shared.

Can a similar SNS sensor be used instead?

Not recommended. These are ECU-coded emission components and must match exact OE + SNS revision to avoid SCR faults or limp mode.
