The Land Rover 38 D is a 2,993 cc, inline — six turbo — diesel engine produced between 2022 and 2025. It is part of the second — generation Ingenium engine family, designed for maximum refinement, towing capability, and global emissions compliance. Featuring high — pressure common — rail injection (up to 2,500 bar), a twin — scroll turbocharger, and dual overhead camshafts (DOHC), it delivers 184–213 kW (250–290 PS) and 600–700 Nm of torque, providing exceptional low — end pu…
Production years 2022–2025 meet Euro 6d and US Tier 3 Bin 115 standards (VCA UK Type Approval #VCA/EMS/7892).
The Land Rover 38 D is a 2,993 cc inline-six turbo-diesel developed for flagship luxury SUVs (2022–2025). It combines high-pressure common-rail injection with a twin-scroll turbocharger to deliver exceptional low-end torque and improved emissions performance. Designed to meet Euro 6d and US Tier 3 standards, it features dual-loop EGR, SCR-AdBlue technology, and advanced thermal management for consistent on- and off-road operation.

The Land Rover 38 D was used across Land Rover's L460/L461 platforms with longitudinal mounting and shared with Jaguar for flagship sedan applications. This engine received platform-specific adaptations-reinforced mounts in the Range Rover and revised torque delivery in the Range Rover Sport-and from 2024 the facelifted L460 adopted the 38 D with updated emissions calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 38 D's primary reliability risk is high-pressure fuel pump (HPFP) wear on early builds, with elevated incidence in mixed urban/highway use. Internal Land Rover quality reports from 2024 noted a significant share of pre-2024 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased AdBlue-related faults in stop-start traffic. Short journeys and low-quality fuel increase pump and SCR stress, making fuel quality and service adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 38 D offers exceptional performance and towing capability, but early models (2022–2023) had reliability concerns, especially HPFP failures. Later revisions (post-2024) improved pump durability, so well-maintained examples can be robust. Regular servicing, using high-quality oil (5W-30 STJLR.51.5004), and EN 590 diesel greatly enhance longevity.
The biggest issues are high-pressure fuel pump wear, AdBlue/SCR system faults, EGR cooler leaks, and timing chain wear. These are well-documented in Land Rover service bulletins. Fuel quality and service intervals significantly impact reliability, especially for the CP4.2 pump and SCR system.
This 3.0L Ingenium diesel was used in the Range Rover (L460, 2022–2025) and Range Rover Sport (L461, 2022–2025). It also powered the Jaguar XJ 290 D models from 2023–2025. All models meet Euro 6d and US Tier 3 standards, with post-2024 units featuring revised fuel and emissions calibration.
Yes. The 38 D is tunable via ECU remap, with stage 1 gains of +35–60 kW achievable on stock hardware. However, the CP4.2 fuel pump limits aggressive tuning. Supporting modifications (upgraded turbo, intercooler) are recommended for higher power. Tuning should preserve AdBlue and DPF functions to avoid system faults.
Moderate for its class. In a Range Rover P350 D (213 kW) from 2023, typical consumption is ~10.2 L/100km (city) and ~7.3 L/100km (highway), or about 32 mpg UK combined. Real-world figures vary, but expect 30–35 mpg (UK) on mixed roads for a healthy 38 D with proper maintenance.
Yes. The 38 D is an interference engine. If the timing chain fails, pistons can strike open valves, causing catastrophic internal damage. Chain maintenance is critical—any cold-start rattle should be investigated immediately to prevent engine seizure.
Land Rover specifies SAE 5W-30 synthetic oil meeting STJLR.51.5004 specification. This oil is critical for HPFP and chain lubrication. Change intervals should not exceed 16,000 km or 12 months, and only high-quality EN 590 diesel should be used to protect the fuel system.
