The 308 is a strong family hatchback let down by one critical weakness: the 1.2 PureTech timing chain. This guide covers all reported faults on Mk1 and Mk2 308 models.
This Common Problems guide combines structured analysis β verdicts, risk scoring and cost ranges where we have enough data β with real fault cases pulled directly from MyCarFault's reporting database, so the guidance below reflects what owners actually experience rather than manufacturer specifications alone. Background and analysis come first, followed by the linked fault reports and related guides you can jump to directly using the links above.
The Peugeot 308 has won European Car of the Year and earned genuine respect as a drivers hatchback with excellent ride quality and strong refinement. However, one significant flaw undermines its reputation for used buyers: the 1.2 PureTech three-cylinder petrol engine, also used in the Citroen C3, C4, DS3 and Opel Corsa F, has a documented timing chain weakness that causes premature stretch and, in undetected cases, engine damage.
For a used 308, the safest petrol choice is the 1.6 THP (post-2014 revised units) or 130 THP. The 1.2 PureTech can be a good engine in updated form β confirm the chain has been replaced or the engine is a later build with revised specification. The 2.0 BlueHDi 150 is the most reliable diesel option.
Revised chain and tensioner specifications were introduced from around 2017-2018. Earlier engines remain at risk. PSA offered extended warranty coverage in some markets β check with a dealer.
Rough running, occasional judder, reduced power and P0016 (crankshaft-camshaft correlation) fault code. In severe cases, the engine may not start.
Stellantis extended goodwill repairs in several markets. A dealer can check your VIN against the extended coverage database.
