The Land Rover 30DDTX is a 2,993 cc, inline — six turbocharged diesel engine produced between 2020 and 2023. Part of Jaguar Land Rover's Ingenium engine family, it features high — pressure common — rail injection, a twin — scroll turbocharger, and variable valve timing. In standard tune it delivers 184 kW (250 PS) and 570 Nm of torque, with overboost functionality temporarily increasing torque to 600 Nm for improved overtaking response.
Fitted to models including the Range…
All production years (2020–2023) comply with Euro 6d-Final emissions standards .
The Land Rover 30DDTX is a 2,993 cc inline-six turbocharged diesel engine developed for full-size luxury SUVs (2020–2023). It integrates twin-scroll turbocharging with Bosch CRS 4-25 common-rail injection to deliver smooth, linear power delivery and strong low-end torque. Designed to meet Euro 6d-Final regulations, it balances refinement with emissions control through DPF and SCR systems.

The Land Rover 30DDTX was used across Land Rover's Velar/Discovery platforms with longitudinal mounting and adapted for the Range Rover's premium architecture. This engine received platform-specific tuning-optimized torque curves in the Velar and revised cooling management in the Discovery-and from 2022 the Range Rover L460 adopted the SCR-enhanced 30DDTX variant with updated ECU mapping, 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 30DDTX offers strong performance and towing capability, but pre-2022 models have known EGR cooler cracking issues under mixed driving conditions. Later revisions (2022+) show improved reliability with updated casting and coolant management. When maintained properly—using correct oil (5W-30 JLR STJLR.51.5004) and adhering to service intervals—these engines can reliably exceed 150,000 km.
Primary issues include EGR cooler cracking from thermal cycling, AdBlue/SCR system faults, turbocharger bearing wear, and high-pressure injector wear. These are documented in Land Rover service bulletins P313-0022 and P312-0056. Regular highway driving and using quality diesel significantly reduce failure risk.
The 30DDTX is used in the Range Rover Velar (L560), Discovery (L462), and Range Rover (L460). All models from 2020–2023 with the P300d diesel designation use this engine. All units comply with Euro 6d-Final emissions standards and require AdBlue refills.
Aftermarket ECU tuning is common on the 30DDTX 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 real-world conditions, expect 9.5–11.0 L/100km (26–30 mpg UK) in urban driving and 7.8–8.6 L/100km (33–36 mpg UK) on highways. Combined consumption is approximately 8.8 L/100km (32 mpg UK). DPF regeneration cycles may temporarily reduce efficiency.
Yes. The 30DDTX is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic internal damage. Chain maintenance and timely oil changes are essential to prevent tensioner failure and ensure long-term reliability.
Land Rover specifies 5W-30 synthetic oil meeting STJLR.51.5004 standard. This low-ash formulation protects the DPF and SCR system and ensures proper lubrication of the twin-chain timing system. Oil must be changed every 15,000 km or annually to maintain engine health.
