The Range Rover D 16 Y3 is a 1,999 cc, inline‑four turbo‑diesel engine produced between 2016 and 2020. It features common‑rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard form it delivers 132 kW (180 PS) and 430 Nm of torque, enabling strong low‑rpm responsiveness ideal for urban and highway driving.

All production years 2016–2020 meet Euro 6 emissions standards .
The Range Rover D 16 Y3 is a 1,999 cc inline‑four turbo‑diesel engineered for full‑size luxury SUVs (2016–2020). It combines common‑rail direct injection with a variable geometry turbocharger to deliver strong low‑end torque and efficient cruising. Designed to meet Euro 6 standards, it balances everyday drivability with stringent emissions control.

The Range Rover D 16 Y3 was used across Land Rover's L405 and L494 platforms with longitudinal mounting and no third‑party licensing. This engine received platform-specific adaptations—revised engine mounts in the L494 Sport and updated cooling ducting in the L405—and from mid‑2018 the HPFP upgrade per JLR Service Action Notice, creating minor service part distinctions. 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 D 16 Y3 offers strong torque and good efficiency, but early units (2016–mid‑2018) had HPFP cam lobe wear concerns under frequent short-trip use. Post‑mid‑2018 revisions improved durability. With proper maintenance—especially oil changes and occasional highway driving—this engine can be very dependable.
Main issues include HPFP cam lobe wear, AdBlue/SCR system faults, DPF regeneration failures from low-speed driving, and minor front cover oil seepage. These are documented in JLR service bulletins and are generally manageable with correct servicing.
The D 16 Y3 powers the TD4 variant of the L405 Range Rover (2016–2020) and L494 Range Rover Sport (2016–2020). It is exclusive to Land Rover and not shared with other manufacturers.
Aftermarket ECU tuning is common on the D-16-Y3 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 TD4, expect ~7.2 L/100km (city) and ~5.8 L/100km (highway), or about 48 mpg UK combined. Real-world mixed driving typically yields 42–48 mpg UK, depending on load and driving style.
Yes. Like all modern JLR engines, the D 16 Y3 is an interference design. Timing chain failure—though rare—could cause piston-to-valve contact and severe internal damage. Chain wear is minimal with proper oil maintenance.
JLR specifies 5W‑30 synthetic oil meeting STJLR.03.5004. Always use this exact grade to ensure VVT response, turbo protection, and HPFP lubrication. Change every 16,000 km or 12 months, whichever comes first.
