55496784 SNS498 A2C15955100-01 NOX exhaust gas sensor

55496784 Nitrogen Oxide sensor is factory fitted on GM brand Opel and Vauxhall  Insignia MK2 B Z18 cars with 1.6L CDTi diesel engine.

If you have did on-board computer scan after seeing check engline light on the dashboard and your car is showing any of the fault codes related to nox sensor POSN1 = Position 1, then you'll need to replace it.

It is always recommended to fix this issue as soon as possible to avoid any damages to DPF filter, otherwise diesel particulate matter or soot can clog filter and it will cost you thousands to fix.

NOX stands for Nitrogen Oxide.

Error cleaning may be required, but just once after fitting new NOX sensor, it can be done by yourself, no need to visit dealer.

Information from sensor: ASM-NOXPOSN1.

Continental SNS498 A2C15955100-01 sensor is also kwown as control unit with nox-sensor for emissions control.

55496784 NOX sensor is factory fitted to Vauxhall or Opel cars with diesel engine.

DPF means diesel particulate filter.

What does nox sensor do ?

A nitrogen oxide sensor in short NOX is high temperature part is used in cars to detect and measure out amount of this compound (nitrogen oxides) coming out of exhaust system to ensure, it is mostly found in diesel cars.

Replacement sensor probe with ballast unit will save you a fortune, solve your NOX problems and you will comply with enviromental emissions laws again.
