The Jaguar 8D is a 2,179 cc, inline-four turbo-diesel engine produced between 2010 and 2015. Developed in collaboration with Ford as part of the joint AJD-V6/PSA DW12 platform evolution, it features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard tune, it delivers 120 kW (163 PS) and 400 Nm of torque, providing strong mid-range performance for executive sedans and SUVs.
Fitted to models such as the XF (X250), XK (X150), and Range Rover Evoque (L538), the 8D engine was engineered for smooth refinement and responsive driving dynamics. Emissions compliance was achieved via exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 compliance across its production run.
One documented concern is high-pressure fuel pump (HPFP) degradation under low-fuel conditions, highlighted in Jaguar Technical Service Bulletin JTSB-14-08-01. This issue stems from inadequate lubrication when running near fuel reserve levels. From 2013, Jaguar introduced revised pump calibration and updated maintenance guidelines to mitigate premature wear.

Production years 2010–2015 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5678).
The Jaguar 8D is a 2,179 cc inline-four turbo-diesel engineered for premium saloons and SUVs (2010–2015). It combines common-rail direct injection with variable geometry turbocharging to deliver refined mid-range torque and highway cruising capability. Designed to meet Euro 5 standards, it balances performance with regulated emissions control.

The 8D's VGT turbo provides strong low-end torque ideal for city driving and motorway overtaking but requires consistent use of ultra-low-sulfur diesel (ULSD) meeting EN 590 to prevent high-pressure fuel pump (HPFP) failure. Jaguar WSS-M2C913-D (5W-30) oil is essential due to its thermal stability and compatibility with the EGR/DPF system. Fuel levels should not be allowed to drop below quarter-tank to ensure HPFP lubrication. The SCR system requires periodic AdBlue refills and regeneration cycles; neglect can trigger limp mode. Post-2013 models benefit from updated pump calibration per JTSB-14-08-01, reducing failure incidence.
Oil Specs: Requires Jaguar WSS-M2C913-D (5W-30) specification (Jaguar SIB JTSB-11-20-03). Supersedes ACEA B4.
Emissions: Euro 5 certification applies to all 2010–2015 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under SAE J1349 standards. Output consistent across EU markets (Jaguar TIS Doc. JT-8D-POWER).

The Jaguar 8D was used across Jaguar's X250/X150 platforms with longitudinal mounting and shared design lineage with Land Rover units in the L538 Evoque. This engine received platform-specific adaptations-fuel mapping revisions in the XF and enhanced cooling in the XK-and from 2013, updated HPFP calibration improved reliability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the right-side cylinder block near the exhaust manifold (Jaguar TIS JT-8D-ID). The 8th VIN digit indicates engine type ('D' for diesel). Pre-2013 models use Bosch EDC17CP55 ECU with rectangular diagnostic connector; post-2013 units feature updated HPFP control logic. Critical differentiation from Ford Duratorq: Jaguar 8D has unique intake manifold routing and ECU calibration. Service parts require model-year verification—HPFP assemblies before 2013 are not interchangeable with later revisions (Jaguar SIB JTSB-14-08-01).
The 8D's primary reliability risk is high-pressure fuel pump (HPFP) degradation, with elevated incidence in urban-driven vehicles with frequent low-fuel operation. Internal Jaguar field reports from 2014 indicated a significant share of pre-2013 units required HPFP replacement before 120,000 km, while UK DVSA MOT data shows DPF-related failures are common in short-trip usage. Extended oil intervals and low fuel levels increase pump and injector stress, making adherence to service schedules and fuel management critical.
