MOT fail on Lambda
Just had my CSL fail its MOT on the lambda reading on the fast idle test. Not had any lights on the dash etc. so can not be far out,
I know they have more than one Lambda fitted so is there an easy way to find out which one has failed? Or could there be another cause for the reading? all the exhaust system etc. is standard btw Thanks |

It won t be your Lambda sensor that's failed its just that your co2 reading is too high.....
When the test was done was the engine and exhaust really nice and hot? The cats have to be nice and warm to work efficiently... |
