LTI TX4 2008: MOT failure rate for its age

41.1% of 7,092 MOT tests of the LTI TX4 first registered in 2008 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 99.9 (95% CI 96.2–103.5; 100 = normal for this model at that age): the 2008 build year is no different from other years of the same model at the same age.

How does the 2008 LTI TX4 fail at each age?

Cars built in 2008 were tested at ages 11 to 16 between 2019 and 2024. Each row compares their first-time failure share with what this model normally shows at that age, after allowing for the overall failure level of each test year.

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.
