Apologies for yet another post re: lambda sensors - but as many as I have read I am still not quite clear on something (it's probably quite obvious so am fully prepared to give myself a good facepalm once it is pointed out to me haha)
On a 2012 Clio 200, are both sensors (pre and post cat) the same part number?
From what I have read, I see both part numbers 8200830903 or 8200590431 are referred to as suitable (either seems to be ok as they are the same length - 420mm - and have the rectangular shaped connector).
Understand that there is a different part number for 197/early 200s with the oval connector, but not sure if there is supposed to be a difference between pre and post cat sensors.
If anyone can clarify the above it would be most appreciated!
Cheers
