Volvo V40 1998: MOT failure rate for its age
58.0% of 812 MOT tests of the Volvo V40 first registered in 1998 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 109.0 (95% CI 99.2–118.9; 100 = normal for this model at that age): the 1998 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 | 58.0 | % | all ages tested | 2019–2024 | 812 |
| Index against this model at the same age (95% CI 99.2–118.9) | 109.0 | index | 100 = normal for this model at that age | 2019–2024 | 812 |
| Rank among this model's 15 build years | 15 | of 15 | 1 = fails least for its age | 2019–2024 | 812 |

How does the 1998 Volvo V40 fail at each age?
Cars built in 1998 were tested at ages 21 to 22 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) |
|---|---|---|---|---|---|
| 21 | 489 (rough estimate) | 56.6 | 52.2–61 | 56.2 | 100.7 |
| 22 | 323 (rough estimate) | 60.1 | 54.6–65.3 | 48.6 | 123.6 |

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.
