BMW M5 2015: MOT failure rate for its age
10.7% of 2,415 MOT tests of the BMW M5 first registered in 2015 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 100.4 (95% CI 88.1–112.6; 100 = normal for this model at that age): the 2015 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.
| Measure | Value | Unit | Compared with | Years | Tests |
|---|---|---|---|---|---|
| Failed first time | 10.7 | % | all ages tested | 2019–2024 | 2415 |
| Index against this model at the same age (95% CI 88.1–112.6) | 100.4 | index | 100 = normal for this model at that age | 2019–2024 | 2415 |
| Rank among this model's 6 build years | 4 | of 6 | 1 = fails least for its age | 2019–2024 | 2415 |

How does the 2015 BMW M5 fail at each age?
Cars built in 2015 were tested at ages 4 to 9 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.
| Age | Tests | Failed, % | 95% interval | Normal for this model at that age, % | Index (100 = normal) |
|---|---|---|---|---|---|
| 4 | 446 (rough estimate) | 7.4 | 5.3–10.2 | 8.6 | 86.1 |
| 5 | 408 (rough estimate) | 12.3 | 9.4–15.8 | 10.3 | 119.2 |
| 6 | 407 (rough estimate) | 11.3 | 8.6–14.7 | 11.4 | 99.1 |
| 7 | 401 (rough estimate) | 11.2 | 8.5–14.7 | 12.3 | 91 |
| 8 | 384 (rough estimate) | 10.7 | 8–14.2 | 10.3 | 103.6 |
| 9 | 369 (rough estimate) | 11.7 | 8.8–15.3 | 11.2 | 104.2 |

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.
