What are the common issues with the Peugeot 1.2T engine?
2 Answers
The common issue with the Peugeot 1.2T engine is that its timing belt is soaked in engine oil. As the mileage increases, the wear debris from the timing belt in the oil can clog the oil filter screen, preventing normal oil circulation and triggering warnings. This can lead to abnormal engine wear, and even after replacing the new belt, oil burning may still occur, requiring a major engine overhaul. Taking the 2015 Peugeot 408 1.2T Automatic Luxury Edition as an example: it is a compact 4-door, 5-seater sedan with a length, width, and height of 4750mm, 1820mm, and 1488mm respectively, a wheelbase of 2730mm, and equipped with a 6-speed automatic manual transmission.
I've been driving Peugeot cars for over a decade, and this 1.2T engine has quite a few issues. The most common problem is the aging belt. The belt material in early models was subpar, cracking and disintegrating after just 60,000 to 70,000 kilometers, clogging the oil passages and causing complete engine failure. Repairs can cost over ten thousand yuan. Another issue is excessive oil consumption, requiring top-ups during every maintenance interval, otherwise the warning light comes on. There's also a small chance of turbocharger failure, resulting in sluggish performance. My advice is to visit a professional shop early to replace it with the new improved belt and use synthetic oil for regular maintenance to avoid major headaches. For safety, don't push through if you notice problems—stop and inspect promptly to prevent breakdowns or accidents on the road.
