2015 Peugeot 108 — MOT failures & pass rate
105,266 MOT tests on the 2015 Peugeot 108 are in this dataset, and 86.2% of them passed. City cars of a similar age fail 15.6% of the time, so this is 1.7pp better than the group it competes with. Failures cluster in brakes, tyres and visibility.
What the MOT record shows
No single area dominates — brakes (5.7%) and tyres (5.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are tread depth, wipers and headlamp aim — tread depth alone was recorded 2,781 times.
Condition tracks the odometer closely. Failures run at 9.1% in the 0-30k band and 24.5% in the 150k+ band, a 15.4-point spread — more than double.
Tyres is the most common advisory, noted on 27.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 11.7% of tests failed in 2021 against 15.9% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2015 108
The failure pattern for this year is specific enough to inspect against: brakes accounted for 5.7% of tests. Start there.
- Brakes (5.7% 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.
- Tyres (5.5% 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 (3.9% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
