MOT lamda value

Options
Just been collecting together documents related to my car, and noticed that when my car has its very first MOT in June the lambda value was near the 1.030 limit - actual was 1.026

I believe this is a calculated value, but does this mean my car is likely to fail its MOT next year?

    that value means its running lean
    you could have a slight blow in the exhaust system somewhere or the lambda sensor is on its way out..

    really wont know till you have the emissions checked again if it would fail or pass

    2.6% lean.
    Most likely due to a slight air leak in the exhaust, but could be anything. It could get worse, it could go the other way just as easily. It could even be the calibration of the tester. I'd leave it and see next year.
