My beloved car (1.4 BBY, 2003) has failed the last emission test.
The local service couldn't find the root cause yet. First they wanted to change the lambda sensor, but the old one was still perfect (not a surprise, it was changed 2 years ago). Then they thought the guilty one is the injector in the 4th cylinder, but no, it does not. The catalytic converter has been replaced last December. Since this check I put Cataclean to the tank and went to a 1000 km long trip, where I had 5.8 l/100km (48.7 mpg) fuel consumption.
Today I put E10 to the tank and had a second check. HC went down to 29 but the CO was still high. With a small luck and kindness the guy there was able to measure 0.2 for a moment so the car has passed the MOT, but it was really on the edge. Do you have any idea what to check still? It would be good to avoid such a situation next year...
