The Hyundai D3EA is a 2,996 cc, V6 turbo‑diesel engine produced between 2010 and 2018. It features common rail direct injection, a twin‑scroll variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivered 171 kW (233 PS) and 550 Nm of torque, engineered for refined performance in premium applications.
Fitted to models such as the Grandeur HG, Genesis DH, and Santa Fe (DM), the D3EA was engineered for smooth, high — torque driving w…

All production years 2010–2018 meet Euro 5 emissions standards .
The Hyundai D3EA is a 2,996 cc V6 turbo‑diesel engineered for executive sedans and large SUVs (2010–2018). It combines common‑rail direct injection with a twin‑scroll variable‑geometry turbocharger to deliver strong low‑rpm torque and refined cruising. Designed to meet Euro 5 standards, it balances performance with fuel efficiency and emissions control.

The Hyundai D3EA was used across Hyundai's DH and DM platforms with longitudinal mounting and exclusive to premium applications. This engine received platform-specific adaptations—reinforced subframes in the Genesis DH and modified cooling in the Santa Fe DM—and from 2015 the facelifted Grandeur HG received updated HPFP calibration, creating minor ECU interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The D3EA offers strong performance and refinement, but pre-2015 models have known HPFP reliability concerns. Post-2015 revisions improved fuel system durability. With strict adherence to oil changes (10K–15K km) and use of EN 590 diesel, well-maintained examples can exceed 200,000 km without major issues.
Top issues include HPFP failure (especially pre-2015), DPF clogging from short trips, EGR valve carbon buildup, and turbo actuator sticking. These are documented in Hyundai service bulletins HST‑13‑025 and HST‑15‑018, with clear OEM repair protocols.
The D3EA powered the Genesis (DH, 2011–2016), Grandeur (HG, 2010–2016), and Santa Fe (DM, 2012–2018) in 3.0 CRDi guise. All applications are longitudinal, Euro 5-compliant, and exclusive to markets including Europe, Korea, and Australia.
Aftermarket ECU tuning is common on the D3EA platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Santa Fe DM, expect ~8.2 L/100km city and ~6.1 L/100km highway, or ~40 mpg UK combined. The heavier Genesis DH averages 8.5–9.0 L/100km. Real-world economy depends heavily on driving style and DPF regeneration frequency.
Yes. The D3EA is an interference design. Timing chain failure—though rare due to front-mounted robust chain—could cause piston-to-valve contact. No widespread timing issues reported, but chain tensioner inspection is advised at 150,000 km.
Hyundai specifies ACEA C3-compliant 5W‑30 synthetic oil meeting SP III standard. This low-SAPS formulation protects the DPF and ensures HPFP lubrication. Oil changes every 10,000–15,000 km are critical for longevity.
