Hi, Im Martin. New to all these forums but found the peps on here have all the answers. Valuable source of information.
Driving a 96, 18i A3/FE Its a great car but its got to the age where every thing is going wrong, It just failed the MOT on Emissions As the c/o was to high. Suppose to be 3% but was more like 6%, The Hc were in line but the Lambda failed as well so now I have changed the Lambda with a new one and a second hand mapping sensor, Took it back and it was still no better. SO it looks like I need a new Cat. It sucks having to keep paying out on a car I picked up cheep.

High CO with low hydrocarbons and NOx will argue for a bad O2 sensor (believe that'd be the lambda you mentioned), but before you buy a new catalytic converter have your air-fuel ratio checked. High AFR can lead to high CO, low HC/NOx condition as well (they're related, the O2 sensor tells the ECU how to manage the AFR).
