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 D16B2 was engineered for refined efficiency with responsive torque delivery. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue, allowing full Euro 6 compliance across all markets.
One documented concern is premature wear of the high-pressure fuel pump (HPFP) drive lobe on the camshaft, potentially causing hard starts and fuel pressure faults. This issue is referenced in Land Rover Service Bulletin LTB00489(19), which attributes the problem to marginal surface hardening in early camshaft batches. From mid‑2018, revised camshafts with improved lobe treatment were introduced.
All production years (2016–2020) meet Euro 6 standards (VCA UK Type Approval #VCA/EMS/8912).
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 VGT turbo provides strong low-end torque ideal for relaxed driving, but requires strict adherence to 16,000 km or annual oil changes with Land Rover STJLR.03.5034 (0W-30) oil to protect the HPFP drive lobe and turbo bearings. Extended oil intervals increase risk of cam lobe wear and DPF clogging. Use only EN 590 ultra-low-sulfur diesel; biodiesel blends above B7 are not recommended. Post-mid-2018 engines include updated camshafts per Land Rover SIB LTB00489(19).
Oil Specs: Requires Land Rover STJLR.03.5034 (0W-30) specification (Land Rover SIB LTB00489(19)). Equivalent to ACEA C2 with OEM-specific additives.
Emissions: Euro 6 compliance confirmed for all 2016–2020 builds via WLTP testing (VCA Type Approval #VCA/EMS/8912).
Power Ratings: Measured under ISO 1585 standards (Land Rover TIS Doc. L22‑5150).

ISO 1585: Road vehicles — Engine test code
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.
Locate the engine code stamped on the front timing cover near the crank pulley (Land Rover TIS L22‑5190). The 7th VIN digit indicates engine family ('D' for 2.0L Ingenium diesel). All D16B2 units feature black engine covers with integrated AdBlue dosing module. Critical differentiation from D20B2: D16B2 has 180 PS output and single turbo; D20B2 is 240 PS with twin-turbo. Service parts require production date verification—camshafts before 06/2018 are incompatible with later units due to lobe hardening upgrade (Land Rover SIB LTB00489(19)).
The D16B2's primary reliability risk is HPFP drive lobe wear on early builds, with elevated incidence in high-mileage vehicles and those using non-spec diesel fuel. Land Rover internal quality data from 2020 indicated a measurable uptick in fuel pressure fault codes before 100,000 km, while UK DVSA records show DPF-related warnings as a growing MOT advisory item in urban-driven vehicles. Fuel quality and oil degradation accelerate component fatigue, making fluid specification adherence critical.
Analysis derived from Land Rover technical bulletins (2016–2020) and UK DVSA failure statistics (2018–2025). Repair procedures should follow manufacturer guidelines.
