A model by model, engine by engine guide to which Peugeot, Citroën and DS cars use a wet belt (belt in oil) timing system, and which don’t.
Already know your car has a wet belt? See our PureTech wet belt replacement service.
Two examples of the same model a year apart can have completely different engines, which is why the table below is organised by engine rather than model.

Cross-checked across independent motoring sources. Where sources agreed, we’ve treated it as solid. Where they disagreed, we’ve flagged it below.
| Engine | Models | Years |
|---|---|---|
| 1.0 & 1.2 PureTech petrol (naturally aspirated) Engine code EB2 | Peugeot 208, 2008, 308; Citroën C3, C4 Cactus | c.2012 – 2022 |
| 1.2 PureTech turbo petrol Engine codes EB2DT, EB2DTS, EB2ADTD, EB2ADTX | Peugeot 208, 2008, 308, 3008, 5008, 408, Rifter; Citroën C3, C4, C5, C3 Aircross, C4 Cactus, Berlingo; DS3, DS4, DS7 | c.2014 – 2022/23 |
Common mix-up worth clearing up: the 48V hybrid PureTech engines (codes EB2LTED and EB2LTEDH2), introduced from 2023, switched to a timing chain. But plenty of non-hybrid PureTech cars built in 2023 and after still have the wet belt, so the model year alone isn’t a reliable guide, the engine code is what matters. If your car falls in this range, an engine code or VIN check is the safe answer.
Worth ruling out explicitly, since customers often ask:
Not sure which engine you have?
Check My CarThe clearest way is your V5C logbook or a VIN check, since the model name and year alone aren’t always enough. Bring your registration to us and we’ll check for certain, free of charge.
Most do, from around 2012 up to 2022/23. Because both wet belt and chain versions were sold during the changeover period, an engine code check is the safest way to be certain.
No, the 48V hybrid PureTech engines (codes EB2LTED and EB2LTEDH2) introduced from 2023 use a timing chain. But non-hybrid PureTech cars from the same period can still have the wet belt, so check the engine code rather than assuming from the year.
Fitment has changed over the years in ways that aren’t always obvious from the outside. If you’re not sure, the safest option is to bring your car in and let us check the actual engine rather than go by the model name or year alone.
Yes, they’re two names for the same design. Manufacturers and the wider motor trade use both terms interchangeably for a timing belt that runs submerged in engine oil rather than outside the engine.
