    Default 2.2 direct failed mot on emissions,

    Hi, I have recently bought a 04 reg 2.2 direct vectra sri.

    I took it for MOT today and it failed on the emissions. It seems that the CO %vol is way to high

    (Max limit is 0.300)

    Mine is 6.036

    Also the emission light has come on. although i have noticed this on before then it went off.

    Has anyone eles had this problem or does anyone know what it could be

    Thanks

    Mine failed to.. but only at 0.428.. but was your engine warm? and had a good spin to clean it up.. probaly wont help to get it all the way down.

    Also besides the suggestions above, check for holes in the exchaust.

    Would this be swirl flaps? as this is what it comes up with on a fault reader.

    Would stuck swirl flaps make the co% high. Or could this be an unrelated fault?

    Thanks for your replys
