hi lads . my car has failed the nct twice on high co2 emissions . your allowed to have 0.3%volume max and my car has 0.7%. i have tried numerous things to fix this and then went to my local mechanic to check the emissions and it is always staying at around the 0.7% volume mark . i have tried 3 different cats so this is not the problem . i have checked the map sensor and its fine . i have replaced the o2 sensor (the engine light was not on but i done a diagnostics anyway and it threw up a fault code for the 02 sensor so i replaced it and now the car is not throwing up any fault codes) . i also replaced the air filter . .has anyone got any ideas or also experienced this problem . i really need an nct as you can now get on the spot penalty points at side of road as well as the fine . (thanks to everyone who replied to me in my other thread when i thought it was just a new cat i needed)
