Peugeot 308 Timing Belt: Intervals, Fitment & Warning Signs
A real, documented case: a 308 passed its official recall safety check, then the wet belt failed completely months later, costing £5,400 — here's why the "check" itself may not be reliable.

Confirmed: A Genuine Safety Recall — And a Real, Documented £5,400 Failure After Passing It — Peugeot 308 Timing Belt
If your 308 has the 1.2-litre PureTech petrol engine, this is genuinely the single most important thing to know before anything else on this page. This engine uses a "wet belt" — a timing belt that runs submerged in engine oil rather than in a dry cover — and it has a well-documented, serious history of premature failure. Peugeot issued an official recall (reference JZR) covering 2,212 examples of the 308, 208, and 2008 built between 2017 and 2020. In April 2023, this escalated to a genuinely more serious urgent safety recall: degraded timing belt particles circulating in the engine oil system were found capable of causing loss of brake assistance — a braking safety issue, not simply an engine reliability one.
The official replacement interval has been revised down from an original 10 years/112,000 miles to a considerably shorter 6 years/62,000 miles — treat the shorter figure as the one that matters. Gen3 versions of this engine (2023 onward) were redesigned with a proper timing chain instead, resolving the issue entirely.
Peugeot 308 Timing Belt: Generations, GTi & Engines: Belt or Chain
| T7 (2007–2013), 1.4 VTi petrol & 1.6 HDi diesel | Timing belt — conventional dry belt |
|---|---|
| T9 (2013–2021), 1.6 THP petrol, incl. GTi (2015–2018) | Timing chain — early units have a documented stretch history, improved on later production |
| T9 (2013–2021), 1.2 PureTech petrol | Timing belt — "wet belt" design, see detailed warning above |
| T9 (2013–2021), 1.6/2.0 HDi/BlueHDi diesel | Timing belt — conventional dry belt |
| Current gen (2021–present), 1.2 PureTech petrol | Timing belt (pre-2023 build) or timing chain (2023+ build, mainly hybrid) — check build date, not just registration year |
Peugeot 308 Timing Belt: The Part Where Missing a Deadline Gets Expensive
This is one of the rare maintenance items on the Peugeot 308 where skipping the schedule genuinely risks serious consequences. On the engines affected, a failure here tends to cause damage well beyond the part itself, making the interval more important than on almost any other component.
Peugeot 308 Timing Belt: What It Does
The Peugeot 308's timing belt or chain's whole purpose is keeping the camshafts and crankshaft turning in exact synchronisation, so valves open and close at precisely the right moment relative to the pistons. On "interference" engines, a common design, a failed belt lets pistons and valves collide, with serious internal damage the result.

This tutorial uses a 208 for demonstration but covers the identical 1.2 PureTech engine fitted to the 308. The GTi's 1.6 THP and the diesel range are different jobs entirely.
