Audi A1 2017: MOT failure rate for its age
14.5% of 121,964 MOT tests of the Audi A1 first registered in 2017 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 104.0 (95% CI 102.4–105.5; 100 = normal for this model at that age): close to other build years of the same model at the same age (within 5 points of normal).

How every figure is calculated: methodology. Age, test year and build year are tied together (age = test year − build year), so the test-year level is taken as observed, not estimated.
