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, refined NVH performance, and accessible torque. Emissions compliance is achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, allowing full Euro 6 compliance across all markets.
One documented concern is premature wear of the high‑pressure fuel pump (HPFP) drive lobe, noted in Jaguar Land Rover Service Action Notice JLR‑SAN‑2018‑05. This issue stems from marginal lubrication during frequent short‑trip operation, leading to micro‑pitting on the camshaft. From mid‑2018, JLR introduced a revised HPFP with improved cam follower geometry and hardened cam surfaces.
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 VGT turbo provides strong low-RPM torque ideal for city and motorway use but requires strict adherence to 16,000 km or 12‑month oil change intervals to protect the HPFP drive lobe and turbo bearings. JLR‑approved 5W‑30 oil meeting STJLR.03.5004 is critical due to its specific formulation for chain lubrication and HPFP protection. Frequent short trips without engine warm‑up can accelerate cam lobe wear. Post‑mid‑2018 engines feature an upgraded HPFP per JLR SAN 2018‑05. The SCR/AdBlue and DPF systems mandate occasional sustained highway driving to maintain regeneration cycles and prevent limp‑mode events.
Oil Specs: Requires JLR STJLR.03.5004 (5W‑30) specification (JLR Owner Handbook L405‑2017). Equivalent to ACEA C2 but with tighter soot handling limits.
Emissions: Euro 6 certification applies to all 2016–2020 models (VCA Type Approval #VCA/EMS/3210). Confirmed compliance across EU/UK markets.
Power Ratings: Measured under ISO 1585 standards. Peak output requires EN 590 ultra-low-sulfur diesel (JLR PT‑2020).

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.
Locate the engine code stamped on the left-side engine block near the oil filter housing (JLR TIS P20D‑D16Y3). The 7th VIN digit for TD4 models is 'D' (indicating 2.0L diesel). All D 16 Y3 units use black valve covers with integrated ignition coils. Critical differentiation from petrol variants: diesel engines have visible EGR coolers, AdBlue dosing unit, and lack spark plugs. HPFP part number D16Y3‑9A391‑AA denotes pre‑mid‑2018 units; post‑mid‑2018 uses D16Y3‑9A391‑AB per JLR SAN 2018‑05.
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.
