Hiya i was wondering if anyones got any ideas, my brother-in-law has a 98 audi 2.4 v6, when he took it for its MOT, it failed on the emissions, the lamba was ok, but failed on the CO (is ment to be 0.300 and it was 0.632) and the HC ( is ment to 200 and it was 278). I serviced the car, ie plus, air,oil and filter, put redx in it and made sure the car was red hot wen took it for test. Anyone got any ideas before i have to change the 2 cats?? Any help would be great.
cheers steve
