U 1.1 CRDi (D3FA) vs Kappa 1.0 T-GDI (G3LC)
Side-by-side reliability comparison
Specifications
Character
U 1.1 CRDi (D3FA)
"Three-cylinder 1.1 CRDi diesel (2005-2019) from the Hyundai/Kia U family, used in the Kia Picanto, Hyundai i10 and i20 and Kia Rio. 75 hp, Bosch common rail, very low fuel use. No widespread serious fault is documented; the main costs come from soot clogging the EGR valve and intake swirl flaps in town driving, and early engines can push oil into the intake through the crankcase breather. Owners report 290,000 km and more. Evidence is limited, so the score is capped."
Kappa 1.0 T-GDI (G3LC)
"Three-cylinder 1.0 turbo with direct injection in the i20, i30, Kona, Bayon, Rio, Stonic, Picanto and Ceed. Used-car guides rate it well and report few engine failures. Expect coked injectors and intake carbon at higher mileage, occasional turbo oil leaks, and check that the i20 vacuum-hose recall has been done. Thirstier than its size suggests."
