BMW X1 2018: MOT failure rate for its age
11.7% of 60,484 MOT tests of the BMW X1 first registered in 2018 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 103.7 (95% CI 101.3–106.2; 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).
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 11.7 | % | all ages tested | 2019–2024 | 60484 |
| Index against this model at the same age (95% CI 101.3–106.2) | 103.7 | index | 100 = normal for this model at that age | 2019–2024 | 60484 |
| Rank among this model's 12 build years | 8 | of 12 | 1 = fails least for its age | 2019–2024 | 60484 |

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.
