BMW M5 2011: MOT failure rate for its age
12.4% of 356 MOT tests of the BMW M5 first registered in 2011 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 98.3 (95% CI 69.3–127.4; 100 = normal for this model at that age): the 2011 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 | 12.4 | % | all ages tested | 2019–2024 | 356 |
| Index against this model at the same age (95% CI 69.3–127.4) | 98.3 | index | 100 = normal for this model at that age | 2019–2024 | 356 |
| Rank among this model's 6 build years | 3 | of 6 | 1 = fails least for its age | 2019–2024 | 356 |

How does the 2011 BMW M5 fail at each age?
Cars built in 2011 were tested at ages 8 to 13 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) |
|---|---|---|---|---|---|
| 8 | 97 (rough estimate) | 15.5 | 9.6–24 | 11.5 | 134.1 |
| 9 | 91 (rough estimate) | 6.6 | 3.1–13.6 | 11.7 | 56.5 |
| 10 | 87 (rough estimate) | 12.6 | 7.2–21.2 | 14.3 | 88.4 |
| 11 | 81 (rough estimate) | 14.8 | 8.7–24.1 | 12.9 | 114.4 |

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.
