U 1.1 CRDi (D3FA)
Hyundai/Kia · 1.1L Diesel I3
2005–2019
"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."

Known Issues 3
EGR valve and intake swirl flaps clogged with soot
▸Loss of power, engine warning light, rough idle, black smoke
Soot builds up in the EGR valve and the intake swirl-flap dampers, which MyMotorList says need cleaning about every 50,000 km. A French i20 owner reported EGR trouble around 100,000 km costing about 1,800 EUR at a Hyundai dealer; cleaning is far cheaper than replacement. Worst in short-trip town use.

Engine block internal corrosion (2008 service action)
▸Ask a Hyundai dealer whether the car was part of the service action
Hyundai ran a service action for i10 1.1 CRDi cars built 20 August to 27 September 2008 (70 cars in France): the block could show internal rust. Dealers inspected the cylinders and oil circuit and, if needed, replaced the crankshaft assembly or the complete engine and turbo under warranty (L'argus, 2010). Only that narrow batch is affected.
No Greek-specific data found.
Oil consumption through the crankcase breather (first generation)
▸Oil level dropping between services, oily intake hoses, blue smoke
On the first-generation engine (2005-2010, Euro 4) a ruptured crankcase-ventilation membrane lets oil into the intake (MyMotorList). A 2008 Kia Picanto owner at 293,000 km reported oil consumption. Cost not sourced.
