Aftermarket Nox sensors

[RobbyC]

Hi All- I previously asked a question about replacing my Nox sensor but got no response so here’s a simplified question- has anybody tried using aftermarket sensors from China (AliExpress). They seem to have quite a range of “official” part numbers. Would appreciate any information. Thanks

I would also like to know.

Especially considering the OEM are £600 each and there seem to be vast aftermarket options available with matching OEM part numbers.

I have sourced 2 Hella units from Autodoc, and no garages want to fit them

Matching part numbers for sensors is a bit of a lottery, some work some don't. I bought an after market cam sensor for one of our Ducato's when Fiat had no stock and it was OK, exhaust/emissions stuff is a bit hit and miss.
