The Range Rover 16 HA03AL is a 5,000 cc V8 supercharged petrol engine engineered for full-size luxury SUVs (2017–2022). It combines a twin-screw supercharger with dual injection (direct + port) to deliver high power with improved emissions and reduced intake coking. Designed to meet Euro 6d-Temp standards, it balances performance with regulatory compliance across global markets.

The Range Rover 16 HA03AL was used across Land Rover's L405 and L494 platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced subframes in the L405 and revised engine mounts in the L494 SVR—and from 2020 the facelifted models retained the same engine with updated ECU calibration for RDE compliance. 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.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 16 HA03AL offers strong performance and refinement but has known issues with supercharger bypass actuators and secondary air pumps. Early engines (pre-2020) are more prone to actuator failure. With strict adherence to oil changes (every 15,000 km) and use of 5W-30 STJLR.03.5006 oil, well-maintained examples can exceed 200,000 km reliably.
Top issues include supercharger bypass valve actuator failure, secondary air injection pump faults, timing chain tensioner wear, and direct fuel injector coking. These are documented in Land Rover SIBs 07/2020/11 and 05/2018/07, and commonly appear in high-mileage or poorly maintained vehicles.
The 16 HA03AL powered the Range Rover L405 (2017–2022) and Range Rover Sport L494 (2017–2022) as the 5.0 SC. It was exclusive to these models and not used by other manufacturers. All units meet Euro 6d-Temp emissions standards.
Yes. The 16 HA03AL responds well to ECU remapping, typically gaining +40–70 kW on stock hardware. The Eaton TVS supercharger and forged internals support moderate increases. However, aggressive tuning without upgraded intercooling, fueling, or drivetrain components may reduce longevity and void warranty coverage.
Real-world consumption is ~17.2 L/100km (city) and ~11.8 L/100km (highway), or about 16 mpg UK combined. Expect 14–18 mpg (UK) depending on driving style and vehicle load. Premium 98 RON fuel is recommended for optimal performance and knock prevention.
Yes. The 16 HA03AL is an interference engine. If the timing chain fails or jumps, pistons can collide with open valves, causing severe internal damage. Regular inspection of chain tensioners and guides is essential to prevent catastrophic failure.
Land Rover specifies SAE 5W-30 synthetic oil meeting STJLR.03.5006. This formulation ensures proper lubrication of the supercharger and timing components. Oil should be changed every 15,000 km or annually, whichever comes first.
