Peugeot 108 Clears 84% — Tyres and Wipers Catch Owners

With an 84.55% pass rate across 82,669 tests and an average of just 35,902 miles, the 108 is one of the youngest and highest-passing cars in this batch. Tyre tread depth, wiper blade condition, and brake pad wear account for all three main failure reasons — straightforward maintenance items that owners sometimes overlook on a city car. One 2014 example at 14,000 miles triggered a cascade of dashboard warning lights including engine fault, ABS, and flat tyre indicators simultaneously, diagnosed as an electrical fault by the dealer. Check wiper blades and tyre depth before presenting for test, and on earlier models, verify there are no unresolved electrical fault codes.

Top ten reasons for rejection.

  1. 13 Aug 2017

    Report of 2014 Peugeot 108 at 14,000 miles suddenly suffering strange electrical problem: All of a sudden all the warning lights on the dash came on: engine fault, abs, flat tyre, etc, plus a reduction in power such as the car will not go above 30mph. Peugeot dealer did a diagnostic check, fitted a new ECU,plus numerous sensors, but cannot find the problem. Maybe the earth lead from the battery to the body.

Buying or keeping a 108?

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.

If you own a 108 and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
