2004 Mitsubishi Delica — MOT failures & pass rate
902 MOT tests on the 2004 Mitsubishi Delica are in this dataset, and 68.4% of them passed. All cars of a similar age fail 27.7% of the time, so this is 3.9pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (17.2%) and suspension (17.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, chassis condition and rear fog lamp — component mounting prescribed areas alone was recorded 194 times.
A 150k+ example is materially riskier than a 60-90k one: 35.4% versus 20.9%.
Advisories point at the next bill rather than this one: suspension was flagged on 35.8% of tests without failing them.
The trend is improving — the fail rate fell from 34.4% in 2021 to 29.1% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 35.8% | 323 |
| 2 | Brakes | 34.6% | 312 |
| 3 | Emissions & environmental | 28.3% | 255 |

| 5 | Other defects | 16.9% | 152 |
| 6 | Tyres | 15.2% | 137 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 110 | 20.9% |
| 90-120k | 170 | 27.1% |
| 120-150k | 187 | 31.6% |
| 150k+ | 364 | 35.4% |
Failure rate by age

What to check before buying a 2004 Delica
On a 2004 Delica, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.2% of tests. Check these areas before you commit.
- Lighting & signalling (17.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (17.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Body, structure & corrosion (14.6% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
