All generations and engines together · 76,764 MOT tests in the 2025 data · typical mileage at age 7: 39k
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 49,005 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
The rear (post-catalyst) oxygen sensor on the 1.0-litre engine has a history of failing well before it should, triggering an intermittent engine-management light that comes on for a day or two then vanishes. Forum users report it from around 14,000 miles, and it's not unusual for the same car to need a second sensor a few years later. Peugeot hasn't acknowledged a pattern or issued a TSB; the part itself is cheap, it's the diagnostic chase beforehand that costs.
Rarer but nastier: every warning light comes on at once (engine, ABS, tyre pressure) and the car cuts power, restricting it to a crawl. It's turned up on 108s years apart, a 2014 car at 14,000 miles and a separate 2017 car, with dealers replacing ECUs and sensors without curing it either time. The best guess floating around is a poor earth lead from battery to body, but no confirmed fix or manufacturer acknowledgement exists.
The ETG gearbox on automatic 108s is a clutchless manual, not a torque converter, so slow, jerky changes are normal and not a fault in themselves. What isn't normal is the actuator-driven clutch wearing out early: owners of the mechanically identical Aygo and C1 have reported premature clutch failure from a few hundred miles up to the low 20,000s, with one C1 quoted around £1,400 to replace. Doesn't apply to manual-gearbox cars.
Owners on this shared city-car platform report clonks and creaks developing from the front suspension, struts, bushes and anti-roll bar links, as the cars pick up urban miles and speed-bump abuse. It's a steady wear pattern rather than one dramatic failure, and it lines up with the measured MOT data for this class: suspension is the standout fail category for small city cars like the 108, ahead of every other system checked.
Some owners report brake squeal and judder from corroded front discs at surprisingly low mileage, one case at just 6,000 miles, with Peugeot declining warranty cover on the grounds that disc corrosion isn't a manufacturing defect. It's a genuine split of opinion: short-journey, low-mileage driving lets discs surface-rust between uses, and whether that counts as a fault or ordinary wear is exactly what owners argue about.
