The Land Rover 276DT is a 2,993 cc, inline — six turbo — diesel engine produced between 2018 and 2023 as part of JLR's Ingenium engine family. It features a high — pressure common — rail fuel system (up to 2,000 bar), twin — turbocharging (sequential setup), and DOHC 24 — valve configuration. In standard tune it delivers 172 kW (234 PS) with 500 Nm of torque, while higher — output versions produce up to 221 kW (300 PS) and 700 Nm, providing strong low — end response for off — road and tow…
All production years 2018–2023 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/8901).
The Land Rover 276DT is a 2,993 cc inline-six turbo-diesel engineered for full-size luxury SUVs (2018–2023). It combines high-pressure common-rail injection with sequential twin-turbocharging to deliver seamless power delivery and robust low-end torque. Designed to meet Euro 6d standards, it balances refinement, towing capability, and real-world efficiency.

The Land Rover 276DT was used across Land Rover's L460/L461/L462 platforms with longitudinal mounting. This engine received platform-specific calibrations-exhaust tuning in the Range Rover and intake routing in the Discovery-and from 2021 the facelifted L461 adopted revised ECU mapping and HPFP control, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 276DT's primary reliability risk is high-pressure fuel pump wear in early units (2018–2020), with elevated incidence in mixed urban/highway use. JLR internal field reports from 2019–2022 indicated a significant share of pre-2021 units required HPFP replacement before 120,000 km, while VCA MOT data links DPF regeneration failures to frequent short trips. Extended idling and poor oil quality exacerbate turbo and SCR system stress, making service interval adherence and correct oil specification critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 276DT offers strong low-end torque and excellent towing capability, but early models (2018–2020) are prone to HPFP issues under sustained load. Later revisions (2021+) improved pump durability through hardware and software updates. Well-maintained engines with regular oil changes and proper driving cycles can exceed 200,000 km. Using correct JLR-specified oil is essential for longevity.
The most frequent issues are HPFP wear, DPF regeneration failure, and AdBlue system faults. Oil leaks from the valve cover and CCV system are also common. These are documented in JLR service bulletins and field reports. Regular maintenance and extended driving help prevent DPF and SCR issues.
The 276DT is used in the Range Rover (L460, 2018–2023), Range Rover Sport (L461, 2018–2023), and Discovery (L462, 2018–2023) as the D250 or D300 diesel. All models are Euro 6d compliant and use SCR with AdBlue. It is not shared with Jaguar due to size and mounting constraints.
Yes. The 276DT responds well to ECU remapping, with stage 1 tunes typically adding +30–50 kW. Stock internals are robust, but increased boost and torque can accelerate turbo and DPF wear. Tuning should include updated DPF regeneration logic and use of high-quality fuel and oil to maintain reliability.
In real-world driving, the 276DT achieves approximately 8.5–10.5 L/100km (33–27 mpg UK) in mixed conditions. Highway driving can reach 7.8 L/100km (~36 mpg UK), while city use may exceed 12.0 L/100km (~24 mpg UK) due to stop-start cycles and DPF regeneration.
Yes. The 276DT is an interference engine. If the timing chain fails, pistons can contact valves, resulting in catastrophic internal damage. The triple-chain system is generally robust, but neglected oil changes increase risk. Any timing-related rattles should be investigated immediately.
JLR specifies SAE 5W-30 oil meeting STJLR.51.5116 specification. This low-ash, mid-SAPS oil is critical for DPF and turbo longevity. Oil must be changed every 16,000 km or 12 months. Using incorrect oil can lead to DPF blockage and HPFP failure.
