2004 Peugeot 807 — MOT failures & pass rate
Across 839 MOT tests, the 2004 Peugeot 807 recorded a 69.1% pass rate. That is effectively the same as MPVs of a similar age (30.1% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 20.5% of tests against 16.1% for the next-worst category.
At component level the recurring items are headlamp aim, rbt (sp) and position lamp — headlamp aim alone was recorded 84 times.
Mileage matters less than usual here: the 2004 807 fails 32.6% of the time in the 30-60k band and 30.1% at 150k+, a spread of only 2.5 points.
Tyres is the most common advisory, noted on 33.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 33.3% in 2021 to 26.2% 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 | Tyres | 33.0% | 277 |
| 2 | Brakes | 29.2% | 245 |

| 5 | Other defects | 21.0% | 176 |
| 6 | Body, structure & corrosion | 18.9% | 159 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 43 | 32.6% |
| 60-90k | 131 | 26.7% |

| 120-150k | 197 | 33.5% |
| 150k+ | 176 | 30.1% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2004 807
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 20.5% of tests. Start there.
- Lighting & signalling (20.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (16.1% 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.
- Brakes (13.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
