    hi , my vwpolo failed nct on emmisions. i dont know much about cars and could use some advice. it passed on low idle but failed on high idle and im worried. the readings are LAMBDA 1.05[fail coz needs to be between 0.97 and 1.03] CO 0.78vol% [fail coz its above 0.30%] and finally the HC was 729ppm [fail coz its above 200ppm] should i be worried and is it a costly fix?thanks :)

    It is telling you that the lambda is working hard with the sensors to get the emissions to where they need to be , but ,
    Your carbon dioxide is almost 3 times what it should be and your hydro carbons are almost 4 times.

    Best guess it's a new cat but that's a big bill , 3-700 depending in the year and engine.
