Is there a reason that the NOX sensor must be replaced? At the last service by a reputable Mercedes independent in July on my C200 petrol W205 2015, Star diagnosed a faulty NOX sensor. (There are still none available). The ECU was patched to ignore the fault and the car has performed perfectly since. On my C270CDi I did the modification to disable the EGR which impacts NOX emissions. Is there a good reason why the sensor should be replaced?
