2015 CF Moto Cf — MOT failures & pass rate
Across 299 MOT tests, the 2015 CF Moto Cf recorded a 90.6% pass rate. That is 6.6 percentage points better than all cars of a similar age, which fail at 16.0%. Failures cluster in lighting & signalling, brakes and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (4.7%) and brakes (3.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are stop lamp, headlamp aim and registration plates — stop lamp alone was recorded 8 times.
Suspension is the most common advisory, noted on 14.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.1% of tests failed in 2021 against 16.7% in 2025, the usual pattern as a fleet ages.

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 | 14.4% | 43 |
| 2 | Steering | 7.0% | 21 |
| 3 | Brakes | 6.0% | 18 |
| 4 | Tyres | 4.0% | 12 |
| 5 | Body, structure & corrosion | 2.7% | 8 |
| 6 | Other defects | 2.7% | 8 |
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 | 298 | 9.4% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2015 Cf
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 4.7% of tests. Start there.
- Lighting & signalling (4.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (3.7% 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.
- Body, structure & corrosion (2.3% 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.
