The Range Rover 204D2 Diesel is a 2,997 cc inline‑six turbocharged diesel engine engineered for full-size luxury SUVs (2023–2025). It combines a 48V mild-hybrid system with a single twin-scroll turbocharger to deliver smooth, high-torque performance and improved urban efficiency. Designed to meet Euro 6d standards, it balances responsive power with stringent emissions compliance.

The Range Rover 204D2 Diesel was used across Land Rover's L460 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes in the Range Rover and revised cooling ducts in the Range Rover Sport—and from 2024 the MY24 update introduced minor ECU calibrations for improved AdBlue dosing logic, creating minor software 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 204D2 Diesel is generally robust, with a non-serviceable timing chain and solid MHEV integration. Early concerns focus on AdBlue system reliability in city-driven vehicles. With regular highway driving, proper oil (0W-30 STJLR.03.5021), and AdBlue quality maintenance, it should offer strong long-term reliability.
Top issues include AdBlue dosing valve clogging, 48V battery degradation, EGR cooler leaks, and interrupted DPF regeneration. These are documented in Land Rover SIB LTB00478 and are manageable with proactive driving habits and maintenance.
It powers the 2023–2025 Range Rover (L460) and Range Rover Sport (L461) in D300 trim. It is not used in Defender, Discovery, or older-generation vehicles. All are Euro 6d compliant and feature 48V mild-hybrid technology.
Aftermarket ECU tuning is common on the 20-4D2 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.
Official WLTP combined is ~7.9 L/100km (35.8 mpg UK). Real-world mixed driving averages 8.5–10.5 L/100km (27–33 mpg UK). Highway cruising can achieve ~6.8 L/100km (41 mpg UK), while city driving may exceed 11 L/100km.
No. The 204D2 Diesel uses a non-interference valvetrain design. If the timing chain were to fail (extremely rare), piston-to-valve contact would not occur, reducing catastrophic failure risk.
Land Rover specifies STJLR.03.5021 0W-30 synthetic oil—low-SAPS, ACEA C6 compliant. This protects the turbo, DPF, and SCR system. Change every 16,000 km or 12 months, whichever comes first.
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.
