Land Rover 2.9L 306D1 Engine
Durable Power for Premium Performance

The Land Rover 2.9L 306D1 engine is a powerful and durable straight-six diesel engine renowned for its performance, torque, and long-lasting reliability. Manufactured by BMW and used extensively in Land Rover models during the early 2000s, the 306D1 engine combines German precision engineering with British ruggedness.

It is a 2.9-litre inline-six turbo-diesel engine, designed for vehicles that demand both off-road strength and on-road comfort. Commonly found in the Land Rover Range Rover (L322, 2002–2006) and certain BMW 530d (E39) models, this engine remains one of the most respected units for its balance of power, refinement, and durability—making it a top choice for replacement or reconditioned engine buyers.

The Land Rover 2.9L 306D1 Engine features a displacement of 2926 cc, an inline 6-cylinder configuration, and a DOHC (Double Overhead Camshaft) design. With 24 valves and common-rail direct fuel injection, it produces up to 177 horsepower (130 kW) at 4000 rpm and delivers an impressive 390 Nm of torque at 2000 rpm.
Its single turbocharger with intercooler ensures smooth power delivery and strong mid-range acceleration, essential for towing and off-road driving. The compression ratio of 18:1 gives it exceptional efficiency and low-end torque, while the water-cooled system helps maintain stable operating temperatures even under heavy load. The 306D1’s robust cast-iron block and aluminum cylinder head construction offer both strength and thermal efficiency, making it ideal for long-distance touring and challenging terrain.

Common weaknesses and Maintenance.

While the Land Rover 2.9L 306D1 Engine is known for its dependability, there are some common weaknesses that owners should be aware of. Turbocharger wear and oil leaks from the rocker cover or oil filter housing are among the most frequent issues, particularly in high-mileage units. Some drivers also experience coolant loss caused by failing expansion tanks or water pumps, while EGR valve buildup can reduce performance and fuel efficiency if not cleaned regularly. The timing chain can stretch over time, leading to rattling noises or poor timing if neglected. Routine oil changes every 10,000 km using high-quality 5W-30 synthetic oil and genuine filters are crucial to prevent sludge buildup and prolong the engine’s lifespan.

Overall, the Land Rover 2.9L 306D1 turbo-diesel engine is a proven workhorse that delivers exceptional torque, smooth operation, and reliability. Every used or reconditioned 306D1 engine for sale is compression-tested and quality-assured to meet OEM standards. Whether you’re restoring a Range Rover L322 or performing an engine swap on a compatible BMW model, the 306D1 engine ensures premium diesel performance with long-term dependability.
