Reliability, common problems and owner reviews for the Kia Rio 1.1 / 1.4 CRDi (D3FA / D4FC). Check this before you buy used.
The small CRDi diesels (1.1 three-cylinder, 1.4 four) are remarkably economical and generally sturdy little engines — but they're modern common-rail units, so the usual cautions apply: DPF clogging on short urban trips, EGR sooting and injector wear. Best suited to high-mileage motorway drivers; for ordinary low-mileage town use the petrols are lower-worry. A serviced example with good DPF history is dependable and very frugal.
