2001 Peugeot 806 — MOT failures & pass rate
Across 261 MOT tests, the 2001 Peugeot 806 recorded a 66.3% pass rate. Against MPVs of a similar age (29.7% fail rate), the 2001 806 comes out 4.1pp worse. Failures cluster in suspension, lighting & signalling and body, structure & corrosion.
What the MOT record shows
One area stands out: suspension, recorded in 22.2% of tests against 14.2% for the next-worst category.
At component level the recurring items are component mounting prescribed areas, joints and chassis condition — component mounting prescribed areas alone was recorded 73 times.
Brakes is the most common advisory, noted on 42.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 35.1% of tests failed in 2021 against 40.6% in 2024, the usual pattern as a fleet ages.

What to check before buying a 2001 806
The failure pattern for this year is specific enough to inspect against: suspension accounted for 22.2% of tests. Start there.
- Suspension (22.2% 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 (14.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (13.0% 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.
