2014 Audi R8 — MOT failures & pass rate
Across 1,275 MOT tests, the 2014 Audi R8 recorded a 94.6% pass rate. Coupes & convertibles of a similar age fail 13.2% of the time, so this is 7.8pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (1.4%) and tyres (1.4%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are shock absorbers, rear fog lamp and registration plates — shock absorbers alone was recorded 14 times.
Mileage is the strongest signal on the record: 3.9% of 0-30k cars fail, rising to 8.3% once past 60-90k — 2.2× the risk.
Tyres is the most common advisory, noted on 10.0% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 7.2% in 2021 to 4.8% 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.

| 1 | Tyres | 10.0% | 127 |
| 2 | Brakes | 6.2% | 79 |

| 6 | Visibility | 0.5% | 7 |
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 | 622 | 3.9% |
| 30-60k | 615 | 6.8% |
| 60-90k | 36 | 8.3% |
Failure rate by age
Trend over time

What to check before buying a 2014 R8
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 1.4% of tests. Start there.
- Lighting & signalling (1.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (1.4% 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.
- Emissions & environmental (1.3% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
