Audi S3 2013: MOT failure rate for its age
13.5% of 1,118 MOT tests of the Audi S3 first registered in 2013 failed at the first attempt (2019–2024; retests excluded). Against this model's own normal rate at the same ages the index is 106.5 (95% CI 89.5–123.5; 100 = normal for this model at that age): the 2013 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 2013 Audi S3 fail at each age?
Cars built in 2013 were tested at ages 6 to 11 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) |
|---|---|---|---|---|---|
| 6 | 229 (rough estimate) | 14 | 10.1–19.1 | 10.5 | 133.4 |
| 7 | 222 (rough estimate) | 11.7 | 8.1–16.6 | 11.7 | 100.1 |

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.
