Part numbers, fitment and common faults for Peugeot models — organised by model below.
The 1.2 PureTech Wet Belt: Genuinely the Most Important Thing to Know
If you're looking at any Peugeot fitted with the 1.2-litre PureTech petrol engine — used across the 208, 308, 2008, and 3008, among others — this is worth understanding properly before you buy. Unlike a conventional timing belt, the PureTech's belt runs submerged in engine oil, and early versions of this design (broadly pre-2017) developed a well-documented reputation for premature degradation: the belt material cracks and sheds fragments that circulate through the oil system, potentially blocking oil galleries and causing complete oil starvation. When this happens, the consequences are genuinely severe — UK owners have reported full engine replacement bills of £5,000-£9,000, often after the original three-year warranty had expired, with some failures occurring below 70,000 miles. The problem was serious enough that PSA (Peugeot's parent group, now part of Stellantis) issued a formal recall in 2021 to address it.
The design has genuinely improved since: post-2017 models received a revised "Gen 3" belt with a longer service life, and from 2023, Peugeot introduced an actual timing chain (not a belt at all) on the newer 136bhp mild-hybrid versions, alongside a further reinforced belt on standard non-hybrid units. If you're looking at a pre-2017 PureTech specifically, treat timing belt history as a genuine priority — confirming it's been replaced, or budgeting for it, regardless of what the indicated mileage suggests.
The Single Most Effective Thing an Owner Can Do
Independent research into PureTech reliability is remarkably consistent on one point: oil change frequency is the single biggest factor separating trouble-free examples from expensive failures. The mechanism is specific — unburned fuel can seep past the piston rings and mix into the oil, forming an abrasive contaminant that accelerates belt wear from the inside. This effect is considerably worse on cars doing mostly short journeys or urban stop-start driving, since the engine rarely reaches full operating temperature for long enough to burn off this contamination. Many independent specialists now recommend oil changes every 6,000-8,000 miles on turbocharged PureTech engines — meaningfully more frequent than Peugeot's own standard 10,000-12,000 mile interval — specifically to counter this. If you do mostly short trips, this is genuinely worth adopting regardless of what the service book says.
Diesel Owners: The DPF Needs Motorway Miles to Do Its Job
Diesel PureTech and BlueHDi engines bring the same diesel particulate filter (DPF) considerations common to most modern diesels — the filter traps soot and periodically needs sustained higher-speed driving to burn it off through "regeneration." A diesel Peugeot used mainly for short urban journeys may never complete this cycle, leading to warning lights, reduced power, and in advanced cases the car refusing to start. Separately, if a regeneration cycle is interrupted partway (switching the engine off mid-cycle), unburned fuel can contaminate the engine oil and, if the rising oil level goes unnoticed, cause genuine engine damage over time. If you drive mostly short distances, a petrol model is very likely the lower-risk choice regardless of a diesel's better claimed economy on paper.
Where Peugeot Sits on Overall Reliability
It's worth setting expectations honestly: Peugeot placed 21st out of 32 manufacturers in a recent What Car? reliability survey — a below-average result, though not a dramatic outlier, and models like the 3008 have scored respectably for owner satisfaction even while sitting mid-pack for outright mechanical reliability. Infotainment glitches (freezing, rebooting screens) are also a frequently reported complaint across recent Peugeot models, reflecting a wider industry pattern with touchscreen-heavy dashboards rather than anything Peugeot-specific.
