Peugeot 806 MOT pass rate & common failures
1,163 MOT tests on the Peugeot 806 (1995–2015) give it a 68.3% pass rate. MPVs of a similar age fail 29.9% of the time, so this is 1.9pp worse than the group it competes with. Its most common failure areas are suspension, lighting & signalling and body, structure & corrosion.
What the MOT record shows
No single area dominates — suspension (16.5%) and lighting & signalling (14.4%) 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, joints and stop lamp — component mounting prescribed areas alone was recorded 188 times.
A 150k+ example is materially riskier than a 0-30k one: 29.8% versus 35.9%.
Advisories point at the next bill rather than this one: suspension was flagged on 43.5% of tests without failing them.
The trend is improving — the fail rate fell from 32.8% in 2021 to 29.6% 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 | 43.5% | 506 |
| 2 | Brakes | 39.0% | 454 |
| 3 | Tyres | 31.4% | 365 |

| 6 | Body, structure & corrosion | 21.8% | 254 |
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 | 92 | 35.9% |
| 60-90k | 84 | 22.6% |
| 90-120k | 180 | 30.6% |

What to check before buying a Peugeot 806
- Suspension (16.5% 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.
- Lighting & signalling (14.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (12.1% 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.
