What are the main advantages of the PureTech 1.2 engine?

Three-cylinder turbo efficiency with genuinely good performance from a tiny displacement Good fuel economy in real-world use - typically 5.5–7 L/100km depending on variant and driving style Start-stop system and low CO2 output make it attractive for urban and environmental use Compact design keeps the engine bay uncluttered and contributes to the car's light weight Despite its documented issues, owners who stay on top of the updated maintenance schedule generally report satisfactory reliability - the engine responds well to attentive servicing

What are common issues and problems with the PureTech 1.2?

The primary maintenance issue with this engine is its "belt-in-oil" timing system. Although the original service schedule specified replacement at 180,000 km, this interval proved unreliable, with one of the most critical side effects being the debris from the disintegrating belt blocking vital oil passages. To mitigate this failure, the manufacturer issued an updated belt in 2017 and drastically shortened the mandatory replacement interval to 100,000 km Increased oil consumption is frequently observed due to the seizing (or 'sticking') of the piston rings In engines equipped with direct injection, carbon buildup on the valves becomes noticeable over time The oil pump is a component that often fails prematurely. Since the design does not incorporate hydraulic lifters, periodic valve
