Hi everyone. I am new to bimmer forums : )
I have a PO420 code!! this was shown during diagnostics in DIS V57. I was using INPA and got the car up to full operating temps. I took a photo of the screen. I am not sure what these figures mean?
im hoping its an O2 sensor & not the cat? but not sure : ( ?? any help is appreciated. Dont want to spend lots of money on a new cat if it is an o2 sensor problem?

p.s My BMW is an 318i SE E46 1999 (M43) engine
