2017 Chausson Flash — MOT failures & pass rate
The 2017 Chausson Flash passed 86.8% of its 288 recorded MOT tests. That is effectively the same as all cars of a similar age (12.5% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 11.5% of tests against 2.4% for the next-worst category.
At component level the recurring items are outline marker lamp, registration plate lamp(s) and headlamp aim — outline marker lamp alone was recorded 12 times.
Condition tracks the odometer closely. Failures run at 9.0% in the 0-30k band and 27.8% in the 60-90k band, a 18.8-point spread — more than double.
Brakes is the most common advisory, noted on 16.3% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 13.6% in 2021 to 7.8% 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 | 16.3% | 47 |
| 2 | Suspension | 9.4% | 27 |
| 3 | Tyres | 8.3% | 24 |

| 5 | Visibility | 3.1% | 9 |
| 6 | Other defects | 2.1% | 6 |
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 | 178 | 9.0% |
| 30-60k | 56 | 12.5% |
| 60-90k | 54 | 27.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2017 Flash
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.5% of tests. Start there.
- Lighting & signalling (11.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (2.4% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Brakes (2.1% 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.
