The Hyundai D4FA-01 is a 1,685 cc, inline‑four turbo‑diesel engine produced between 2010 and 2019. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), delivering 94–100 kW (128–136 PS) with torque between 265–280 Nm. The compact displacement enables strong low-end responsiveness ideal for urban and mixed driving conditions.
Fitted to models such as the i30 (GD), ix20, and Veloster, including variants like the 1.7 CRDi, the D4FA-01 was engineered for fuel efficiency, refined operation, and compliance with tightening emissions standards. Emissions control relied on exhaust gas recirculation (EGR) and a diesel particulate filter (DPF), allowing Euro 5 compliance across most markets from launch.
One documented concern is high-pressure fuel pump (HPFP) wear linked to fuel lubricity issues, highlighted in Hyundai Service Bulletin HST‑13‑021. This stems from the Bosch CP3 pump’s sensitivity to ultra-low-sulfur diesel with inadequate additive packages. From 2014, Hyundai introduced revised pump internals and updated fuel filtration per the bulletin.

Production years 2010–2013 meet Euro 5 standards; 2014–2019 models comply with Euro 6 in select markets (VCA UK Type Approval #VCA/EMS/7890).
The Hyundai D4FA-01 is a 1,685 cc inline‑four turbo‑diesel engineered for compact hatchbacks and crossovers (2010–2019). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver responsive low‑rpm torque and efficient urban commuting. Designed to meet Euro 5 (and Euro 6 in later models), it balances drivability with emissions compliance.

The compact VGT turbo provides brisk low-end response but requires strict adherence to 10,000–15,000 km oil change intervals using ACEA C3–compliant oil to protect the HPFP and turbo bearings. Ultra-low-sulfur diesel (EN 590) is mandatory—biofuel contamination or moisture accelerates CP3 pump wear. EGR/DPF systems demand periodic regeneration; frequent short trips may trigger limp mode. Post-2014 models include updated HPFP internals per Hyundai SIB HST‑13‑021.
Oil Specs: Requires ACEA C3 / Hyundai SP III (5W-30) specification (Hyundai Owner’s Manual 2015). Not backward compatible with older ACEA B4 oils.
Emissions: Euro 5 certification applies to 2010–2013 models (VCA Type Approval #VCA/EMS/7890). Euro 6 applies to 2014–2019 units in EU/UK markets only.
Power Ratings: Measured under SAE J1349 standards. 100 kW output requires EN 590 diesel with ≤10 ppm sulfur (Hyundai TIS Doc. H23‑1150).

The Hyundai D4FA-01 was used across Hyundai's GD and PB platforms with transverse mounting. This engine received platform-specific adaptations—revised cooling in the i30 GD and compact exhaust routing in the ix20—and from 2014 the facelifted i30 adopted updated EGR/DPF hardware, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crank pulley (Hyundai TIS H22‑7750). The 7th VIN digit indicates engine family ('D' for D4FA series). Pre-2014 models use Bosch CP3.2 HPFP with silver fuel rail; post-2014 units use CP3.3 with black rail and updated cam follower. Critical differentiation from Gamma petrol engines: D4FA-01 has EGR cooler on left bank and DPF canister under floor. Service parts require production date verification—HPFP kits for engines before 09/2014 are incompatible with later units due to seal redesign (Hyundai SIB HST‑13‑021).
The D4FA-01's primary reliability risk is high-pressure fuel pump (HPFP) wear on early builds, with elevated incidence in regions with inconsistent diesel quality. Hyundai internal data from 2015 indicated a measurable rate of HPFP replacements before 100,000 km in non-EN 590 fuel markets, while UK DVSA records show DPF-related MOT failures rising in high-mileage urban vehicles. Short-trip driving and fuel contamination increase pump and EGR stress, making fuel quality and maintenance critical.
