Afternoon , may I ask , is your car doing short journeys at the moment ? .if so my first port of call would be to clear the code & drive at speed on a motorway or dual carriage way for 20 minutes or more . It may well be that the catalytic converter is clogging up as it is not getting hot enough to clear any deposits . Running in a lower gear & at higher revs also helps generate more heat & greater gas flow , just don't go silly !!

I regularly have petrol cars with similar issues during MOT emission testing , oodles of revs & several minutes normally rectifies the issue

Hope it helps

Catalytic converter failure
Open or short within the wiring harness
Poor electrical connection
ECM that has failed or is failing
Failed Sensor or solenoid
