when you do it correctly just count the flashes of the light it will give a repeating sequence of four digits, 10 flashes representing zero

...or should I say “the notorious code 0420”, reading around the forum? I assume if I’ve got an actual driving problem, this isn’t just a £20 faulty sensor? Incidentally, the moment the EML came on, the car was driving nicely,

I’ve reset it...for now.

Heated oxygen sensor bank 1. There are two they are swappable to see if the code changes to 430. they are also testable. it could be a leak on the exhaust. Have a look at page ec 361 onwards fin the ESM for testing and other causesThumbs Up
