A1: It measures nitrogen oxide (NOx) levels in diesel exhaust and sends data to the SCR (AdBlue) system to reduce emissions and improve fuel efficiency.

Q2: Are 29650-4A800 and SNS0832A the same part?

A2: Yes.

• 29650-4A800 = Hyundai OEM part number
• SNS0832A / 5WK97345 = supplier / Continental reference numbers
  They refer to the same NOx sensor used in Hyundai 2.5 CRDi SCR systems.

Q3: Which vehicles use this sensor?

A3: Mainly Hyundai 2.5 CRDi diesel commercial vehicles such as:

• H-1
• i800
• iLoad
• Grand Starex / Cargo

These models use SCR systems to meet emissions standards in 2014–2020 diesel variants.

Q4: Where is this sensor installed?

A4: It is installed in the exhaust aftertreatment system, typically as SCR inlet or outlet NOx sensor depending on configuration.

Q5: What are common failure symptoms?

A5:

• Engine warning light
