Audi A8 2013: MOT failure rate for its age
10.5% of 4,797 MOT tests of the Audi A8 first registered in 2013 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 94.0 (95% CI 85.8–102.2; 100 = normal for this model at that age): the 2013 build year is no different from other years of the same model at the same age.

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.
