The Range Rover D 16 A8 is a 2,993 cc, V6 turbo‑diesel engine produced between 2016 and 2019. It features a dual overhead camshaft (DOHC) layout with 24 valves and high — pressure common — rail direct fuel injection. In standard form it delivered 190 kW (258 PS) and 600 Nm of torque, providing strong low — end pull and refined cruising typical of modern diesel V6s.
Fitted exclusively to the L405 Range Rover and Range Rover Sport (2016–2019 MY), the D 16 A8 was engineered for smooth,…
Production years 2016–2019 meet Euro 6b standards (VCA UK Type Approval #VCA/EMS/7891). No Euro 6d variants were produced for this engine code.
The Range Rover D 16 A8 is a 2,993 cc V6 turbo-diesel engine engineered for full-size luxury SUVs (2016–2019). It combines DOHC architecture with a twin-turbocharger system and high-pressure common-rail injection to deliver smooth, high-torque performance. Designed to meet Euro 6b emissions standards, it balances refinement with robust off-road and towing capability.

The Range Rover D 16 A8 was used exclusively in Land Rover's L405 platform with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts and bespoke exhaust manifolding—and from 2020 was replaced by the mild-hybrid Ingenium inline‑six diesel, creating hard interchange limits. All adaptations are documented in OEM technical bulletins.
The D 16 A8's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in high-idle or towing usage. Land Rover internal quality data from 2018 indicated a notable share of pre-2018 engines requiring tensioner replacement before 100,000 km, while UK DVSA records show DPF-related faults as a common MOT emissions failure. Frequent cold starts and extended idling accelerate component fatigue, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The D 16 A8 offers smooth V6 diesel performance but early models (2016–2018) had timing chain tensioner issues. Post‑mid‑2018 revisions improved durability. With regular oil changes using ACEA C3 5W‑30, proper DPF regeneration through highway driving, and attention to fuel quality, it can be dependable beyond 200,000 km.
Top issues include timing chain tensioner wear, DPF clogging in short-trip use, high-pressure fuel pump failure, and EGR cooler leaks. These are documented in Land Rover TSBs and commonly seen in high-mileage or urban-driven examples. Emissions-related faults are frequent without sufficient highway driving.
This engine was used only in the L405 Range Rover and L494 Range Rover Sport from model years 2016 to 2019 in the TD6 variant. It was not shared with Jaguar or other Land Rover models. No transverse or licensed applications exist for this engine code.
Yes. The D 16 A8 responds well to ECU remapping, with stage 1 tunes yielding ~25–35 kW gains. Supporting modifications (downpipe, intercooler) allow further increases. However, excessive tuning may strain the fuel system and turbochargers. Most owners retain stock or mild tunes for daily reliability.
Real-world consumption is ~9.2 L/100km (city) and ~7.1 L/100km (highway), or about 32 mpg UK combined. Expect 28–34 mpg (UK) on mixed roads. Fuel economy suffers with short trips due to DPF regeneration demands and engine warm-up cycles.
Yes. The D 16 A8 is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. Prompt attention to chain rattle or timing faults is essential to avoid major repairs.
Land Rover specifies SAE 5W‑30 synthetic oil meeting ACEA C3 and JLR STJLR.03.5004 standards. Change every 16,000 km or annually. Correct low-SAPS oil is vital for DPF protection and timing chain lubrication in the high-stress V6 diesel environment.
