Reliability, common problems and owner reviews for the Citroen C3 Aircross 1.2 PureTech (EB2). Check this before you buy used.
The 1.2 PureTech turbo (EB2, shared right across Peugeot/Citroën/Opel — 208/2008/Corsa F/308) is lively, refined and award-winning on paper, but it's the engine to be most careful with here: the pre-facelift cars use a wet timing belt (belt-in-oil) that degrades and sheds material, which can block the oil pickup and destroy the engine — a notorious, expensive failure that triggered extended warranties and many rebuilds. There are also oil-dilution and tensioner issues. Later (≈2022+) cars moved to a chain and are far better. Buy a wet-belt car only with documented early belt replacement and obsessive oil changes; otherwise prefer a chain-era car or the diesel.
