O2 Sensor?

[Shifu]

Cheers Shifu, sounds good to me.
By WRT do you mean ECU Editor or similar?
Do you know if I need to bridge the contacts once the plug is disconnected or is it that all sorted in the above?

I can't remember if it is an option in ECU Editor but it is in WRT for sure. You do not need to bridge anything. It disables the error message in ECU so it will not chuck the F1 light.
