NOX sensor location

Post by daisydog »

Hi i was under the car last night looking for the nox sensor (although just laid on floor so not best views) but i couldnt locate the nox sensor.

Does anyone have a picture or the location of where the nox sensor should be on a 65 plate, c4 hatchback

thanks

It depends on the system - there may be an upstream and a downstream DeNOx sensor.

Pop your VIN up (automasked on post submission) so I can see exactly what you have.

Ok, so it is located in the intermediate part of the exhaust, so past the rear box going towards the front of the vehicle, look for the flexible mount of the intermediate pipe and it should be about 6-12" further up. It looks like this:
