Hi everyone,

I'm new to the forum and looking for assistance regarding my 2017 Discovery sport TD4 SE. The engine management light is on and having read the code with a simple reader the code is P0030 which I understand to be the pre-cat 02 sensor (bank 1 sensor 1). Only problem I have is where do I find it ? Is it something I can fix myself ? LR want £190 to diagnose ! any help much appreciated
