Reliability, common problems and owner reviews for the Citroen C3 III 1.2 PureTech (EB2 turbo / NA). Check this before you buy used.
The 1.2 PureTech (EB2 — shared across the 208/2008/Corsa/C3 Aircross) powers the C3 III; the naturally-aspirated 83-PS version is less stressed, but the turbo cars are the ones to be careful with: the wet timing belt (belt-in-oil) degrades and sheds material that can block the oil pickup and destroy the engine — a notorious, expensive failure with extended warranties and rebuilds, plus oil-dilution and tensioner issues. Later production moved to a chain. Buy a wet-belt turbo only with documented early belt replacement and obsessive oil changes; the naturally-aspirated or a chain-era car is the safer C3.
