The Hyundai D6EA is a 2,959 cc, V6 turbo‑diesel engine produced between 2010 and 2018. It features common rail direct injection, a single variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC) per bank. In standard form it delivers 184 kW (250 PS) and 570 Nm of torque, offering smooth, high‑output performance with strong towing capability.
Fitted to premium models such as the Genesis (DH), Santa Fe (DM), and Grandeur (HG), the D6EA was engineered for ref…
Production years 2010–2014 meet Euro 5 standards; 2015–2018 models meet Euro 6 emissions standards .
The Hyundai D6EA is a 2,959 cc V6 turbo‑diesel engineered for large sedans and SUVs (2010–2018). It combines Bosch common‑rail injection with a single variable‑geometry turbocharger to deliver high torque and smooth refinement. Designed to meet Euro 5 (pre‑2015) and Euro 6 (post‑2015) standards universally, it balances performance with stringent emissions compliance.

The Hyundai D6EA was used across Hyundai's DH/DM/HG platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes in the Santa Fe DM for towing and acoustic insulation in the Genesis DH for NVH refinement—and from 2015 the facelifted Grandeur HG adopted updated HPFP hardware per SIB EM‑2016‑03, creating minor service part distinctions. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D6EA is generally robust with smooth power delivery and strong towing capacity, but early units (2010–2014) had HPFP sensitivity to poor diesel quality. Post-2015 revisions improved fuel system durability. With proper maintenance—quality diesel, timely oil changes, and AdBlue management—it can exceed 250,000 km reliably.
Top issues include HPFP wear (especially with low-lubricity diesel), AdBlue/SCR system faults, EGR cooler leaks, and VGT actuator calibration drift. These are documented in Hyundai SIBs and typically arise after 100,000–140,000 km under adverse conditions.
The D6EA powered the Genesis (DH, 2011–2016), Santa Fe (DM, 2012–2018), and Grandeur/Azera (HG, 2013–2018) in 3.0 CRDi or 3.0 e-VGT trims. It was not used in Kia or licensed to other manufacturers. Pre-2015 variants meet Euro 5; post-2015 meet Euro 6.
Aftermarket ECU tuning is common on the D6EA 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 4WD, expect ~8.5 L/100km (city) and ~6.8 L/100km (highway), or ~40 mpg UK combined. Real-world mixed driving typically yields 35–42 mpg UK. Economy drops significantly when towing or in stop-start urban conditions.
Yes. The D6EA is an interference engine. If either timing chain fails (rare but possible), piston-to-valve contact can cause catastrophic damage. However, the front-mounted dual-chain design is more reliable than rear-mounted systems in earlier Hyundai diesels.
Hyundai specifies SP-grade 5W‑30 oil meeting ACEA C3 and Hyundai SP standards. This low-SAPS oil protects the DPF and SCR system. Change every 15,000 km or 12 months, whichever comes first, especially under heavy load or hot climates.
