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.
Fitted to the L494 Range Rover Sport and L405 Range Rover, the D 16 Y3 was engineered for fuel efficiency, refine…
All production years 2016–2020 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/3210).
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.
The D 16 Y3's primary reliability risk is high-pressure fuel pump (HPFP) drive lobe wear on the camshaft, with elevated incidence in vehicles used predominantly for short urban trips. JLR internal field data from 2019 indicated a measurable uptick in HPFP-related DTCs before 80,000 km in pre‑mid‑2018 builds, while UK DVSA records show minimal emissions-related failures due to robust SCR/DPF control. Inadequate warm-up cycles increase thermal and mechanical stress on the cam-follower interface, making driving pattern and service adherence critical.
Analysis derived from Jaguar Land Rover technical bulletins (2016–2020) and UK DVSA failure statistics (2016–2020). 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.
Yes. ECU remaps typically yield +20–35 kW safely on stock hardware, as the inline‑4 architecture handles increased torque well. Supporting upgrades (intercooler, exhaust) help sustain reliability. Always use EN 590 diesel with tuned maps.
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.
