2014 Peugeot 308 1.6L Diesel · WG64 LVA

The 1.2 PureTech three-cylinder petrol engine utilises a wet timing belt operating submerged in engine oil. Fuel contamination and thermal stress cause belt rubber to degrade, shedding fibrous particles into the engine sump. These particles block the oil pump strainer, causing severe oil starvation, vacuum pump failure, and loss of assisted braking (UK recall R/2020/331), with catastrophic engine failure if unaddressed.

The central 9.7-inch touchscreen controls navigation, radio, and all ventilation and heater settings. On early SMEG and later NAC units, internal memory corruption and software bugs cause freezing, black screens, sluggish response, and random reboots. When the screen freezes, occupants cannot adjust cabin heating, fan speeds, or windscreen demisting.

On 2013–2018 T9 models, the hollow rear torsion beam axle can develop internal stress clicks or creaks over uneven surfaces and road camber changes. The metallic creaking originates from internal axle welding and damping voids. Peugeot issued technical service bulletins advising technicians to inject expanding structural polyurethane foam into the beam or replace the axle.
