2018 Peugeot 108 — MOT failures & pass rate
Across 45,869 MOT tests, the 2018 Peugeot 108 recorded a 91.0% pass rate. City cars of a similar age fail at 9.7%, so the 2018 108 sits squarely on the average. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (4.1%) and visibility (4.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and brake pads — wipers alone was recorded 1,330 times.
Condition tracks the odometer closely. Failures run at 7.0% in the 0-30k band and 20.7% in the 90-120k band, a 13.7-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 24.0% of tests without failing them.
The trend is worsening — 5.7% of tests failed in 2021 against 11.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2018 108
On a 2018 108, tyres is what the MOT record says goes wrong most — it appeared in 4.1% of tests. Check these areas before you commit.
- Tyres (4.1% 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 (4.0% 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 (2.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
