All about the Kia Carens 4All about the 1.1 / 1.4 / 1.6 / 1.7 CRDi (Hyundai-Kia U2) engine
The 1.7 CRDi (Hyundai-Kia U2) engine was fitted to the Kia Carens 4 (2013–2019). In the EU that is 65.7 % of all new cars of this generation.
Versions: 1.7, 1.7 116 hp, 1.7 141 hp, 1.7 136 hp.
The most expensive known risk is timing chain stretch at high mileage: it usually appears at 120,000–250,000 km and costs €700–1,800 to fix.
✓ The faults of this engine were checked against sources (10/2026). Each item has at least two independent sources or an official recall or parts-maker technical note.
Signs: DPF light, power loss or limp mode, oil level on the dipstick rising above max
Fix: Drive long enough at steady speed for regeneration or run a forced one, check the pressure sensor, change diluted oil early; clean or replace the DPF if it is blocked
Signs: Power loss, limp mode, EGR fault codes, rough running
Fix: Check the EGR valve in live data; clean it together with the throttle flap, replace the valve if it sticks
Signs: Sudden loss of power, engine light, fault code P2015
Fix: Check wiring and voltage, clean the manifold if the flaps stick, fit the modified actuator (Hyundai/Kia 28320-2A410)
Signs: Hard starting, rough idle, smoke, knocking noise, injector correction values out of range
Fix: Read injector corrections and do a leak-off test; replace or recondition the faulty injector and code it to the ECU
Signs: Rattle for a few seconds after a cold start, camshaft/crankshaft correlation fault codes
Fix: Check chain stretch (correlation values, tensioner travel) and replace chain, guides and tensioner as a kit before it can jump
Signs: Slipping, high bite point
Fix: Replace clutch kit
Signs: Rattle at idle, vibration pulling away
Fix: Replace with clutch
Signs: Delayed or harsh shifts
Fix: Fluid service, repair
Typical routine maintenance cost for 100,000 km: €2,400–5,750. Sum of the services and wear parts in the plan above (about 15,000 km a year, independent workshop), without faults.
