Failed emission - new cat required or not?

    Looking for some advice on whether I need a new cat or not or could possibly still pass NCT without replacing it.

    Car details
    - 2004 Hyundai Getz 1.1L Petrol
    - Failed emissions test on High idle reading for CO only
    - - CO reading was 0.31 vol% - Failure on this car is anything over 0.20%
    - - Lambda reading 1.01 - passed as failure reading between 0.97 and 1.03
    - - HC reading 20ppm, well below fail rate of 200ppm so passed as well

    I know a failed CO reading could be because of many different reasons, but from people's experience, are the CO reading well over or was it a close call and could potentially pass if put through again?

    Reason I'm asking is I want to sell the car - other than failed NCT it's actually a great runaround for someone. I have it for sale at €350 since it hasn't passed, but these are listed on adverts/DD for €1k plus if it had NCT, so wondering is it worth the effort fixing this issue up or not?

    NCT fail sheet attached.

    Cheers folks!

    It's not close. Possibly a new cat is needed, I suggest checking with a local exhaust place.

    A new catalytic converter should be around 3/400, possibly less if you get a universal.

    Has it been serviced recently/to schedule? What condition is the air-filter in?

    Hasn't been services recently no, but was serviced fairly regularly if I remember correctly - last NCT test was done 18 months ago and it's been off the road since, so not sure if that'll make difference now. Not sure about the air filter but can check later.

    It seems to be burning clean enough - there's a chance that a dirty air-filter is starving it of oxygen a bit, thus generating excess CO.

    ok, thanks for the info, I'll check that first before I go down the route of a new cat

    If it's been off the road for 18 months then I'd service it and also maybe throw some additive in with a full tank of petrol.
    Then drive it fairly high in the revs for a few miles to clean it out. Have the engine up to temp when you arrive at the test centre.
    Check the condition of the timing belt if possible because rubber doesn't like sitting idle for long periods.
