Is the Doblo getting worse?
The fail rate rose 2.5 points to 31.2% from 2022 to 2025, against a rising rate across all cars.
| Year | Tests | Median age | Fail rate | All cars | |
|---|---|---|---|---|---|
| 2022 | 50,690 | — | 28.7% | 22.5% | |
| 2023 | 48,375 | — | 30.2% | 22.8% | |
| 2024 | 40,584 | — | 31.1% | 23.2% | |
| 2025 | 39,118 | — | 31.2% | 22.6% |
Fail rate is first attempts at class 4 tests. Median age is the age of a typical Doblo 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 Doblo in 2025, counted by how many tests each one appeared on.
- 1Coil spring: fractured or broken2,282 tests
- 2Malfunction indicator lamp: inoperative or indicates a malfunction1,286 tests
- 3Pins and bushes: pin or bush excessively worn1,062 tests
- 4Tread depth: tread depth below requirements of 1.6mm1,030 tests

- 6Headlamp aim: projected beam image is obviously incorrect849 tests
- 7Wipers: does not clear the windscreen effectively800 tests
- 8Exhaust system: has a major leak of exhaust gases789 tests
What wears out first
Advisories are the tester flagging wear that is still legal. A typical Doblo collects 2.77 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.
