Sorry about the backing track, but I think this may be it?

Nice one. Mine is slightly different but this helped loads. It’s kinda hidden underneath. 
 

matt from the post you linked has also replied with photos also. 
 

Thanks a lot. Hopefully I’m on the way to getting this sorted. 

You need to know what sensor it is. There’s at least 4 egt sensors

The one under the cat

Is that the one circled in my previous photo?

No it’s under the cat that’s on the left. The one circled is sensor 1

I can’t see any wires or plugs in that area. Got any pics of where it is? On mine I can only see 2 plugs/wires. One that’s goes to the sensor that you can see on top and the one I circled.
