Nox sensor Bank 1

[chalkie888]

Hi all, engine light on on my 2015 C220d bluetec diagnosed as Nox sensor bank 1. Garage quotes about £450 for the part. I am looking at AUTODOC APP and see there are many more cost effective (cheaper) options. Is there a particular brand that should be sourced? Any to be avoided? TIA

There are several versions of sensor and some require ECU software updates.
Personally I'd get the latest version with the latest software version.

450 seems pretty cheap tbf. What brand is that, you get what you pay for, then again he who pays says
