Hi guys,
this is my first post on this forum, as I have recently acquired a 206 GTi which needs to get through the MoT.

can anyone tell me if the 2 O2 sensors (before and after cat) on the 206 GTi are both the same?

I have a P0420 engine code and I/M Readiness status throwing up the CAT, O2S, HO2S, EGR and 2AIR all as being not ready.
I'm hoping that its just an O2 sensor at fault, but want to know if they are both the same?
Unless anyone can tell me other things to check.

Also, does anyone know the drive-cycle for this car, so I can clear the codes and run the drive cycle.
