The Hyundai D4BH is a 2,476 cc, inline‑four turbo‑diesel engine produced between 1995 and 2005. It features indirect injection, a fixed — geometry turbocharger, and SOHC 8‑valve architecture. In standard form it delivered 55–63 kW (75–86 PS) with torque figures between 165–192 Nm, offering robust low — end pull for light commercial and passenger use.
Fitted to models such as the H1 (A1) Starex, Grace (H100), and Porter (D24), the D4BH was engineered for durability and eas…

Production years 1995–1999 meet no formal EU emissions standard; 2000–2005 models meet Euro 2 standards depending on market .
The Hyundai D4BH is a 2,476 cc inline‑four turbo‑diesel engineered for light commercial vehicles and MPVs (1995–2005). It combines indirect injection with a fixed-geometry turbocharger to deliver strong low‑rpm torque and mechanical simplicity. Designed to meet Euro 2 (in later builds), it prioritizes serviceability and durability over refinement.

The Hyundai D4BH was used across Hyundai's H100/Starex platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced sump in the Porter and modified exhaust routing in the Grace—and from 2000 the Starex II adopted a revised coolant jacket and head gasket, creating 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 D4BH is mechanically robust but early models (1995–1999) suffer from head gasket issues under high load. Post-2000 revisions improved cooling and gasket design. With regular oil changes, clean diesel, and proper coolant maintenance, well-cared-for examples can exceed 300,000 km reliably.
Top issues include head gasket failure (pre-2000), turbo oil seal leaks, Bosch VE pump wear, and exhaust manifold cracks. Cooling system neglect and poor fuel quality accelerate these failures. Hyundai TSB‑97‑08 specifically addresses the head gasket concern.
The D4BH powered the H1 Starex (1995–2005), Grace/H100 van (1995–2002), and Porter light truck (1996–2004). It was never used in passenger sedans. All applications are longitudinal, rear-wheel-drive or 4WD configurations.
Limited tuning potential due to indirect injection and mechanical pump. Minor gains (~5–8 kW) are possible via turbo boost increase and pump recalibration, but risk head gasket or manifold failure. Not recommended for daily drivers; stock reliability is preferred.
In a Starex van, expect 9.5–11.0 L/100km (25–22 mpg UK) combined. The Porter truck may see 10–12 L/100km depending on load. Economy suffers with short trips due to inefficient warm-up of indirect injection system.
No. The D4BH uses a gear-driven SOHC with sufficient valve-to-piston clearance. Timing gear failure will stop the engine but typically does not cause internal damage.
Hyundai specifies API CF or ACEA B3 diesel oil, typically 10W‑40 viscosity. Modern low-SAPS oils (e.g., C3) are not suitable. Change every 7,500 km or 6 months to protect the turbo and injection pump.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
Transparency in gaps
A missing or unverified value does not mean the manufacturer has withheld it. We distinguish information not yet verified, information not available to us, and information explicitly not disclosed by the source.
