Citroen Relay 2020: MOT failure rate for its age

17.2% of 657 MOT tests of the Citroen Relay first registered in 2020 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 84.7 (95% CI 69.1–100.3; 100 = normal for this model at that age): the 2020 build year is no different from other years of the same model at the same age. This is a rough estimate from a smaller sample.

How does the 2020 Citroen Relay fail at each age?

Cars built in 2020 were tested at ages 3 to 4 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.
