2004 Iveco Daily — MOT failures & pass rate
Across 1,078 MOT tests, the 2004 Iveco Daily recorded a 71.2% pass rate. That is 1.1 percentage points better than vans of a similar age, which fail at 29.9%. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (21.4%) and brakes (18.6%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, rbt (sp) and rigid brake pipes — service brake performance alone was recorded 118 times.
Mileage is the strongest signal on the record: 28.6% of 0-30k cars fail, rising to 33.3% once past 150k.
Advisories point at the next bill rather than this one: brakes was flagged on 38.9% of tests without failing them.
The trend is improving — the fail rate fell from 30.4% in 2021 to 28.4% 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 | Brakes | 38.9% | 419 |
| 2 | Suspension | 30.0% | 323 |
| 3 | Body, structure & corrosion | 26.3% | 283 |
| 4 | Lighting & signalling | 17.0% | 183 |
| 5 | Tyres | 14.9% | 161 |
| 6 | Emissions & environmental | 14.1% | 152 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 35 | 28.6% |
| 30-60k | 139 | 19.4% |
| 60-90k | 132 | 28.8% |
| 90-120k | 160 | 24.4% |
| 120-150k | 227 | 29.5% |
| 150k+ | 360 | 33.3% |

What to check before buying a 2004 Daily
On a 2004 Daily, lighting & signalling is what the MOT record says goes wrong most — it appeared in 21.4% of tests. Check these areas before you commit.
- Lighting & signalling (21.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (18.6% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Body, structure & corrosion (10.5% 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.
