The Jaguar DC is a 2,993 cc, inline-six, turbocharged diesel engine produced between 2010 and 2015. Developed in collaboration with Ford as part of the joint AJD-V6/V8 programme, it features common-rail direct injection, variable geometry turbocharging, and double overhead camshafts. In standard tune, it delivered 177 kW (240 PS) and 500 Nm of torque, providing strong low-end pull and refined motorway performance.
Fitted to the XF, XK, and XJ models, including the popular XF 2.2D and XJ 3.0D variants, the DC engine was engineered for a balance of refinement, fuel efficiency, and responsive driving dynamics. Emissions compliance was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 compliance across its production run.
One documented technical concern is DPF clogging in vehicles used primarily for short urban journeys, highlighted in Jaguar Technical Information Service Bulletin JAG-TIS-4512. Inadequate regeneration cycles due to frequent cold starts and low exhaust temperatures reduce filter efficiency. From 2013, Jaguar introduced revised EGR cooling calibration and updated DPF regeneration logic to improve urban reliability.
Jaguar
Production years 2010–2015 meet Euro 5 emissions standards (EU Regulation (EC) No 715/2007, VCA UK Type Approval #VCA/JAG/DC/2010).
The Jaguar DC is a 2,993 cc inline-six turbo-diesel engineered for executive and grand tourer applications (2010–2015). It combines common-rail direct injection with a single variable-geometry turbocharger to deliver strong low-RPM torque and smooth cruising. Designed to meet Euro 5 standards, it balances refinement with everyday economy.

The single VGT turbo provides strong low-RPM torque ideal for urban and highway driving but requires regular highway runs to support DPF regeneration. SAE 5W-30 C3 oil meeting Jaguar TXW-50-001 is critical for turbo and chain lubrication. Short-trip driving leads to incomplete DPF regeneration, increasing backpressure and risk of limp mode. The Bosch CP4 fuel pump demands ultra-low-sulfur diesel (ULSD) meeting EN 590 to prevent high-pressure system failure. EGR and SCR systems require periodic inspection; AdBlue levels must be maintained to prevent start-up inhibition. Post-2013 models feature improved regeneration logic, reducing urban reliability risks.
Oil Specs: Requires SAE 5W-30 C3 meeting Jaguar TXW-50-001 (Jaguar SIB JAG-OIL-2011). Supersedes ACEA C3 standards.
Emissions: Euro 5 certification applies to all 2010–2015 models (VCA Type Approval #VCA/JAG/DC/2010). SCR system required for compliance.
Power Ratings: Measured under ECER 85 standards. Output reflects engine-only test with full exhaust system and emissions controls.

The Jaguar DC was used across Jaguar's XF/XJ/XK platforms with longitudinal mounting and no licensed external applications. This engine received model-specific tuning adjustments-variable intake manifolds on the XJ and revised exhaust manifolds on the XK-and from 2013 the facelifted XF and XJ models adopted updated EGR and DPF control logic, creating software compatibility limits. All adaptations are documented in OEM technical bulletins.
Locate the engine serial number stamped on the machined pad at the front of the right-hand cylinder block (Jaguar TIS AJD-ID-001). The "DC" designation is cast into the cylinder head near the cam cover. XF 2.2D models feature a single VGT turbo with black heat shielding; XJ 3.0D units have revised exhaust routing. Critical differentiation from AJ-V8: The DC has a diesel-specific fuel rail and high-pressure pump. Service parts require model-year verification—DPF control modules for pre-2013 models are incompatible with post-2013 ECU revisions due to updated regeneration programming (Jaguar SIB JAG-DPF-2013).
The DC's primary reliability risk is DPF clogging in urban-driven vehicles, with elevated incidence in short-trip usage. Jaguar internal field reports from 2012–2014 noted a significant number of 2.2D models requiring forced regeneration or DPF replacement before 80,000 km, while UK DVSA MOT records show DPF and EGR faults as frequent causes of advisory notices. Frequent cold starts and low-exhaust temperatures inhibit regeneration, making regular highway driving and correct oil selection critical.
