Reliability, common problems and owner reviews for the Citroen C4 III 1.2 PureTech (EB2 turbo). Check this before you buy used.
The 1.2 PureTech turbo (EB2 — shared across the Peugeot 308/3008/508, Opel Grandland and Corsa) is lively and refined, but it's the engine to be most careful with: the wet-timing-belt (belt-in-oil) cars degrade and shed belt material that can block the oil pickup and destroy the engine — a notorious, expensive failure with extended warranties and many rebuilds, plus oil-dilution and tensioner issues. Stellantis moved later production to a chain (≈2022+/3-cyl revisions), which is far better. On this late-platform C4, verify exactly which timing setup the car has; buy a wet-belt car only with documented early belt replacement and obsessive oil changes, or prefer the diesel/electric.
