Is the 407 getting worse?
The fail rate rose 1.8 points to 38.9% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (1.4 points). Read it as the fleet getting older rather than the model changing.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 14,432 | 15 | 37.1% | 22.5% | |
| 2023 | 11,583 | 16 | 37.8% | 22.8% | |
| 2024 | 8,103 | 17 | 38.4% | 23.2% | |
| 2025 | 6,293 | 18 | 38.9% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical 407 at its test that year, and it is the number to watch: across the whole fleet each extra year of age adds roughly 1.9 points to the fail rate, so a model whose age and fail rate rise together is simply getting older.
The exact defects that fail it
Every failure item DVSA recorded against a 407 in 2025, counted by how many tests each one appeared on.
- 1Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt675 tests
- 2Position lamp: not working344 tests
- 3Ball joint: ball joint excessively worn300 tests
- 4Anti-lock braking system: warning lamp indicates an ABS fault280 tests
- 5Pins and bushes: pin or bush excessively worn268 tests
- 6Stop lamp: not working250 tests
- 7Washers: provides insufficient washer liquid236 tests
- 8Condition: has ply or cords exposed217 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical 407 collects 3.16 of them per test, and these are the ones that come up most. Treat it as the running-repairs list for the next year or two.
- 1Tread depth: tread depth below requirements of 1.6mm1,398 tests
- 2Brake discs: in such a condition that it is seriously weakened1,245 tests
- 3Engine oil leaks: leaking excessively from engine1,240 tests
- 4Condition: has a tear, caused by separation or partial failure of its structure692 tests
- 5Linkage ball joints: ball joint excessively worn660 tests
- 6Pins and bushes: pin or bush excessively worn548 tests
- 7Ball joint: ball joint excessively worn540 tests
- 8Brake pads: less than 1.5 mm thick492 tests
Questions
What is the Peugeot 407 MOT pass rate?
61.1% of the 6,295 Peugeot 407 first-attempt MOTs in 2025 passed. The fail rate of 38.9% compares with 22.6% across all cars. A further 8.2% passed after a defect was fixed during the test visit.
What does a Peugeot 407 usually fail on?
The single most common failure is "Joints: constant velocity boot split or insecure, no longer prevents the ingress of dirt", recorded on 675 failed tests, followed by "Position lamp: not working" and "Ball joint: ball joint excessively worn". By section, lamps, reflectors and electrical equipment appears in 43.6% of failures, suspension appears in 38.7% of failures, brakes appears in 37.8% of failures.
Does age change the odds?
Sharply. At 3 to 5 years old the fail rate was n/a%; at 14+ years it was 38.9%. The median Peugeot 407 tested in 2025 was 18 years old with 121,015 miles.
Is the Peugeot 407 getting less reliable?
The fail rate rose 1.8 points to 38.9% from 2022 to 2025 while the median one tested aged 3 years, which is about what ageing alone predicts (1.4 points). Read it as the fleet getting older rather than the model changing.
