2020 Peugeot 108 — MOT failures & pass rate
Across 15,077 MOT tests, the 2020 Peugeot 108 recorded a 92.6% pass rate. That is effectively the same as city cars of a similar age (7.6% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (4.0%) and visibility (2.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, brake pads and headlamp aim — wipers alone was recorded 262 times.
Condition tracks the odometer closely. Failures run at 6.4% in the 0-30k band and 16.2% in the 60-90k band, a 9.9-point spread — more than double.
Tyres is the most common advisory, noted on 19.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 3.0% of tests failed in 2022 against 9.2% 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 | Tyres | 19.2% | 2,890 |
| 2 | Brakes | 14.7% | 2,217 |

| 4 | Other defects | 4.2% | 639 |
| 5 | Visibility | 2.5% | 381 |
| 6 | Lighting & signalling | 1.8% | 265 |
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 | 12,336 | 6.4% |
| 30-60k | 2,566 | 11.7% |
| 60-90k | 154 | 16.2% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

| 2022 | 199 | 3.0% |
| 2023 | 4,954 | 5.4% |
| 2024 | 4,884 | 7.7% |
| 2025 | 5,034 | 9.2% |
What to check before buying a 2020 108
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.0% of tests. Start there.
- Tyres (4.0% 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.
- Visibility (2.5% 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.
- Brakes (2.5% 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.
