Peugeot 308 timing belt cost
Which drive you have depends on the generation and the badge. Every Mk1 (2007–2013) petrol is a chain and every Mk1 diesel a conventional dry belt — no Mk1 has a wet belt at all. From 2014 the 1.2 PureTech petrol brought the wet belt-in-oil design, and it stayed on non-hybrid cars until the end of 2024 even after the hybrids moved to a chain. A timing belt change at a UK independent garage typically costs £225–£640 for a Peugeot 308 (belt, tensioner and water pump), depending on engine.

Wet-belt warning
Some Peugeot 308 engines use a wet belt that runs inside the engine in oil. These can shed material if neglected, blocking the oil pump and risking serious engine damage. Use the right oil, change on time, and have it inspected if you hear a rattle on start-up. Check the engine rows below to see if yours is affected — or see our full UK wet-belt engine list.
Does the Peugeot 308 have a belt or chain?
It depends on the engine. Here's the belt-vs-chain breakdown for the main UK Peugeot 308 engines, with typical manufacturer replacement intervals (always confirm against your own handbook):
| Engine | Type | Interval |
|---|---|---|
1.4 VTi / 1.6 VTi petrol (2007–2013) Chain, so no cambelt bill — but a cold-start rattle means the chain or tensioner is stretched and must be fixed before it jumps. | Timing chain | No set interval |
1.6 THP turbo petrol (2007–2013) The notorious Prince-family engine: chain stretch and tensioner bleed-down from 60,000–80,000 miles give a cold-start rattle and timing-correlation fault codes. Replace chain, tensioner, guides, sprockets and both dephasers as a set. | Timing chain | No set interval |
1.6 HDi diesel (2007–2014) Dry external belt. The 10-year limit never changed across any schedule revision and every Mk1 is now well past it, so mileage is academic — do belt, tensioner, idler and water pump together. | Timing belt | 112,000 mi / 10 yr |
2.0 HDi diesel (2007–2013) Dry external belt, interference engine. Age is the binding limit on these now, not mileage. | Timing belt | 120,000 mi / 10 yr |
1.2 PureTech petrol (2014–2025) Wet belt-in-oil. The belt sheds rubber into the sump and blocks the oil-pump strainer and vacuum pump, so you can lose oil pressure and brake servo assistance before hearing anything. Over 6 years or 62,500 miles, change it regardless of how the belt looks. | Wet belt (in oil) | 62,000 mi / 6 yr |
1.6 THP / PureTech turbo petrol (2014–2021) Chain-driven, no cambelt bill — budget instead for the known Prince-family chain and tensioner issues, and treat any start-up rattle as urgent. | Timing chain | No set interval |
1.6 BlueHDi diesel (2015–2017) Dry external belt. A long official interval, so on a 2015–2017 car the 10-year clock has already expired even at low mileage. | Timing belt | 112,000 mi / 10 yr |
1.5 BlueHDi diesel (2017 on) A conventional DRY belt, not belt-in-oil, whatever the lists say. The belt is not what kills this engine — the short cam-to-cam chain is. A rattle, unexplained oil consumption or power loss means it has stretched, and Stellantis covers the repair to 10 years / 150,000 miles on engines built October 2017 to January 2023. | Timing belt | 112,000 mi / 10 yr |
2.0 BlueHDi diesel (2014–2020) Belt-driven with a short cam chain, and there is a documented pattern of premature belt failure well inside the nominal interval — do not run this one to the number. | Timing belt | 100,000 mi / 10 yr |
1.2 Hybrid 48V petrol (2024 on) The third-generation PureTech in the 48V hybrids is chain-driven, so no wet-belt service and none of the wet-belt risk. | Timing chain | No set interval |

Peugeot 308 timing belt cost
For belt engines, a full timing belt service (belt, tensioner and water pump) at a UK independent garage typically costs £225–£640. Main dealers charge 30–50% more. Chain-driven variants have no scheduled change but cost more in labour if a chain fails.
Key things to know
- No Mk1 308 (2007–2013) has a wet belt. Every petrol is a chain and every diesel a conventional dry belt.
- From 2014 to the end of 2024, a 1.2 PureTech 308 has a wet belt — the Mk2 never got a chain version at all.
- On a 2024 car the badge decides, not the year: Hybrid 136/145 is a chain, PureTech 130 is a wet belt, and they were sold alongside each other for about eleven months.
- The 1.5 BlueHDi diesel is NOT a wet belt despite appearing on most wet-belt lists. Its weak point is the cam-to-cam chain, and there is a Stellantis scheme covering it.
Good question
Questions Okay gets asked a lot
How much does a timing belt cost for a Peugeot 308?
+
A timing belt replacement on a Peugeot 308 typically costs £225–£640 at a UK independent garage in 2026, covering the belt, tensioner and water pump together. The exact figure depends on the engine and your area; main dealers charge more. Use our cost calculator to estimate the price for your specific car and region.
Does the Peugeot 308 have a wet belt?
+
Only the 1.2 PureTech petrol, and only from 2014 onwards. That engine runs its timing belt inside the engine in oil, and Stellantis cut the interval to 6 years or 62,500 miles after widespread early failures — there is also a compensation scheme covering qualifying cars to 10 years or 112,000 miles. No Mk1 308 has a wet belt of any kind: its petrols are chain-driven and its diesels use conventional dry belts. The 1.5 BlueHDi diesel is frequently listed as a wet belt and is not one; its documented problem is a cam-to-cam chain, covered by a separate Stellantis scheme.
What happens if the timing belt snaps on a Peugeot 308?
+
Its belt-driven engines are interference designs, which means if the belt snaps the pistons strike the open valves. That causes bent valves and often piston and cylinder-head damage — a repair that frequently runs to four figures and can write off an older car. This is why replacing the belt on schedule, by age as well as mileage, is far cheaper than risking a failure.
