Reliability, common problems and owner reviews for the Citroen C5 Aircross 1.2 / 1.6 PureTech (EB2 / EP6 turbo). Check this before you buy used.
The PureTech turbo petrols are punchy and economical, but the 1.2 three-cylinder is the one to scrutinise: it uses a cam belt that runs in oil ('wet belt') which degrades over time and can shed debris that blocks the oil pump — neglected examples have suffered serious damage — and some use oil. PSA shortened belt intervals and revised parts. The 1.6 PureTech (180hp) is chain-driven and stronger but a hard-working turbo. A documented car with the wet belt done on a strict interval and clean oil can be fine; an unknown-history 1.2 is a genuine risk.
