2015 Chausson Flash — MOT failures & pass rate
505 MOT tests on the 2015 Chausson Flash are in this dataset, and 89.7% of them passed. All cars of a similar age fail 16.5% of the time, so this is 6.2pp better than the group it competes with. Failures cluster in lighting & signalling, visibility and seat belts & restraints.
What the MOT record shows
No single area dominates — lighting & signalling (5.0%) and visibility (4.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and pins and bushes — wipers alone was recorded 26 times.
Brakes is the most common advisory, noted on 10.3% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.4% of tests failed in 2021 against 10.9% in 2025, the usual pattern as a fleet ages.

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 | 373 | 9.7% |
| 30-60k | 111 | 11.7% |
Failure rate by age
Trend over time

What to check before buying a 2015 Flash
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 5.0% of tests. Start there.
- Lighting & signalling (5.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (4.8% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Seat belts & restraints (1.8% of tests): Belt damage or faulty pretensioners — usually straightforward but safety-critical. Typical repair: £50–£300.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
