Which nox sensor??

[C12jwalls]

Right I've had the dreaded adblue range issue.

This came on a long journey, 650 mile range with the engine management light. After another 30 Miles the adblue went back up to 2500 range. But the engine light remained.

Shoved the carista on saying the usual p20 codes. Relating to the nox sensor.

After using my mates autel Diagnostic it says the nox is at full contamination.

So I'm presuming it's in need of replacement the van has covered 195k.

So which one is best to use and if so any links

For a 2017 2.0 102 bhp
Startline

Thanks
