The Hyundai D4EB is a 1,995 cc, inline‑four turbo‑diesel engine produced between 2009 and 2015. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 100 kW (136 PS) and 320 Nm of torque, with strong low‑rpm pulling power for responsive urban and highway driving.
Fitted to models such as the i40 (VF), Sonata (YF), and Santa Fe (CM), the D4EB was engineered for fuel efficiency and smooth refinement without compromising drivability. Emissions compliance was achieved through cooled exhaust gas recirculation (EGR), a diesel oxidation catalyst (DOC), and a diesel particulate filter (DPF), meeting Euro 5 standards across all markets.
One documented concern is premature wear of the high-pressure fuel pump (HPFP), highlighted in Hyundai Service Information Bulletin EM‑2013‑04. This issue stems from insufficient lubricity in ultra-low-sulfur diesel environments, particularly under frequent short-trip usage. From mid‑2012, Hyundai introduced revised HPFP internals and updated calibration to mitigate early failure.
All production years 2009–2015 meet Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/3421).
The Hyundai D4EB is a 1,995 cc inline‑four turbo‑diesel engineered for mid‑size sedans and SUVs (2009–2015). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver responsive torque and refined operation. Designed to meet Euro 5 standards universally, it balances everyday drivability with emissions compliance.

The D4EB delivers responsive low-end torque ideal for city and motorway use but requires strict adherence to 15,000 km oil change intervals using Hyundai SP 5W-30 to protect the Bosch CP3.4 high-pressure fuel pump. Ultra-low-sulfur diesel (EN 590) with adequate lubricity is essential—fuel additives may be necessary in regions with poor diesel quality. DPF regeneration cycles must not be interrupted; frequent short trips increase soot accumulation. Post-2012 engines include HPFP upgrades per SIB EM‑2013‑04. EGR cooler fouling is common after 100,000 km and should be inspected during major services.
Oil Specs: Requires Hyundai SP 5W-30 (ACEA C3) specification (Hyundai SIB EM‑2013‑04). Not interchangeable with older ACEA B4 oils.
Emissions: Euro 5 certification applies to all 2009–2015 models (VCA Type Approval #VCA/EMS/3421). No market exceptions.
Power Ratings: Measured under SAE J1349 standards. Output consistent across global markets due to Euro 5 homologation (Hyundai TIS EM‑D4EB‑01).

The Hyundai D4EB was used across Hyundai's VF/YF/CM platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the i40 VF for NVH refinement and reinforced subframes in the Santa Fe CM for towing—and from mid‑2012 the facelifted Sonata YF adopted updated HPFP hardware per SIB EM‑2013‑04, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (Hyundai TIS EM‑D4EB‑05). The 7th VIN digit is 'D' for D4EB-equipped vehicles. All D4EB engines feature a black plastic valve cover with '2.0 CRDi' branding and a single DPF mounted on the exhaust manifold. Critical differentiation from R2.0 CRDi (D4EA): D4EB uses Bosch EDC17C10 ECU with CAN bus architecture; D4EA uses Denso ECU. HPFP part numbers changed in 06/2012—verify via Hyundai EPC before ordering replacements (SIB EM‑2013‑04).
The D4EB's primary reliability risk is high-pressure fuel pump (HPFP) wear under low-lubricity diesel conditions, with elevated incidence in short-trip urban use. Hyundai internal data from 2013 indicated a measurable uptick in HPFP replacements before 80,000 km in markets with marginal diesel quality, while UK DVSA records show DPF-related MOT failures are uncommon due to robust regeneration logic. Frequent cold starts and infrequent highway driving increase aftertreatment stress, making fuel quality and driving pattern critical.
