Changing NOX Sensor Position B on 2018 Vauxhall insignia B 2.0 Turbo Diesel
This video is my journey from having an Engine Management Light (EML) warning, then diagnosing a NOX Sensor B fault, then buying a new sensor and replacing the faulty sensor.
I'm not a professional mechanic so if you have any issues please seek assistance from a trained mechanic, workshop or garage.
I won't put the part number on here as it is available from the parts dealers when you tell them your number plate, registration number.
Sensors are available on eBay for £150 and the one I bought from GSF Parts locally was £330. This was cheaper to do that the cost of the dealer doing it for me as they wanted £750 to change over this sensor.
