The Range Rover D16B2 is a 1,999 cc, inline‑four turbocharged diesel engine produced between 2016 and 2020. It features common‑rail direct injection, dual overhead camshafts (DOHC), and a variable‑geometry turbocharger (VGT). In standard form it delivers 132 kW (180 PS) and 430 Nm of torque, enabling strong low‑end response ideal for urban and highway driving.
Fitted to models such as the L494 Range Rover Sport and L405 Range Rover, including the SD4 and TD4 trims, the D1…
All production years (2016–2020) meet Euro 6 standards .
The Range Rover D16B2 is a 1,999 cc inline‑four turbocharged diesel engineered for premium SUV applications (2016–2020). It combines common-rail direct injection with a variable-geometry turbocharger to deliver strong low-rpm torque and efficient cruising. Designed to meet Euro 6 emissions standards, it balances performance with regulatory compliance and drivability.

The Range Rover D16B2 was used across Land Rover's L405 and L494 platforms with longitudinal mounting. This engine received platform-specific adaptations—revised engine mounts in the L405 and updated AdBlue tank routing in the L494—and from mid‑2018 the camshaft was upgraded, 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 D16B2 offers strong low-end torque and refined diesel efficiency, but early models (2016–2017) had camshaft lobe concerns. Mid-2018 revisions improved durability. With proper maintenance—especially oil changes using 0W-30 STJLR.03.5034 and correct diesel fuel—well-cared-for examples can exceed 200,000 km reliably.
Top issues include HPFP drive lobe wear, DPF clogging from short trips, EGR cooler leaks, and AdBlue system crystallization. These are documented in Land Rover SIB LTB00489(19) and TIS service procedures. Fuel and oil quality significantly influence longevity.
The D16B2 powers the Range Rover (L405, 2016–2020) and Range Rover Sport (L494, 2016–2020) in TD4 and SD4 trims. All meet Euro 6 emissions with SCR/AdBlue, DPF, and EGR systems.
Aftermarket ECU tuning is common on the D-16B2 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 a Range Rover Sport TD4, expect ~6.8 L/100km (city) and ~5.2 L/100km (highway), or ~48 mpg UK combined. Real-world mixed driving typically yields 42–50 mpg UK. Urban driving reduces economy due to DPF regeneration cycles.
Yes. The D16B2 is an interference engine. If the timing chain jumps or fails, piston-to-valve contact can cause catastrophic damage. Prompt attention to any timing-related fault codes is essential to prevent engine destruction.
Land Rover specifies 0W-30 synthetic oil meeting STJLR.03.5034 (or newer). This low-viscosity, low-SAPS oil protects the DPF and ensures proper cam lobe lubrication. Change intervals should not exceed 16,000 km or 12 months.
