The Land Rover 306D1 is a 2,993 cc, inline — six turbo — diesel engine produced between 2004 and 2016. It is part of the Ford/PSA joint — venture TDDi engine family, later refined under Land Rover's stewardship for use in full — size SUVs. Featuring common — rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 128–150 kW (174–204 PS) and 440–470 Nm of torque, providing strong low — end pulling power for off — road and towi…
Production years 2004–2009 meet Euro 4 standards; 2010–2016 models meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/3456).
The Land Rover 306D1 is a 2,993 cc inline-six turbo-diesel engineered for full-size luxury and utility SUVs (2004–2016). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-end torque and improved fuel economy. Designed to meet Euro 4 and Euro 5 emissions standards, it integrates EGR and DPF technologies while maintaining off-road capability and towing performance.

The Land Rover 306D1 was used across Land Rover's L322/L319 platforms with longitudinal mounting and shared with Volvo for heavy-duty applications. This engine received platform-specific adaptations-reinforced mounts in the Discovery and revised torque delivery in the Range Rover-and from 2010 the facelifted Discovery 4 adopted the 306D1 with updated emissions calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 306D1's primary reliability risk is high-pressure fuel pump (HPFP) failure on early builds, with elevated incidence in mixed urban/highway use. Internal Land Rover quality reports from 2011 noted a significant share of pre-2010 engines requiring HPFP replacement before 120,000 km, while UK DVSA records show increased DPF-related faults in stop-start traffic. Short journeys and low-quality fuel increase pump and DPF 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 306D1 offers strong torque and towing capability, but early models (2004–2008) had reliability concerns, especially HPFP failures. Later revisions (post-2010) improved pump durability, so well-maintained examples can be robust. Regular servicing, using high-quality oil (5W-30 LR007210), and EN 590 diesel greatly enhance longevity.
The biggest issues are high-pressure fuel pump wear, DPF clogging, 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 CP3 pump and DPF system.
This 3.0L TDV6 was used in the Range Rover (L322, 2004–2012), Discovery 3 (2004–2009), and Discovery 4 (2010–2016). It also powered the Volvo XC90 D5 (2005–2014). All models meet Euro 4 (pre-2010) or Euro 5 (2010–2016) standards, with post-2010 units featuring revised fuel and emissions calibration.
Yes. The 306D1 is tunable via ECU remap, with stage 1 gains of +25–40 kW achievable on stock hardware. However, the CP3 fuel pump limits aggressive tuning. Supporting modifications (upgraded turbo, intercooler) are recommended for higher power. Tuning should preserve DPF functions to avoid system faults.
Moderate for its class. In a Discovery 4 TDV6 204 (150 kW) from 2012, typical consumption is ~10.5 L/100km (city) and ~7.8 L/100km (highway), or about 30 mpg UK combined. Real-world figures vary, but expect 25–32 mpg (UK) on mixed roads for a healthy 306D1 with proper maintenance.
Yes. The 306D1 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 LR007210 or Shell SPIRAX S6 ATF DX specification. This oil is critical for HPFP and chain lubrication. Change intervals should not exceed 15,000 km or 12 months, and only high-quality EN 590 diesel should be used to protect the fuel system.
