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 pop…

Production years 2010–2015 meet Euro 5 emissions standards (EU Regulation (EC) No 715/2007,.
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DC engine is fundamentally robust when operated under recommended conditions. Long-term reliability depends on regular highway driving to support DPF regeneration, use of correct oil (5W-30 C3), and adherence to service intervals. Urban-driven examples often face DPF and EGR issues, but well-maintained vehicles with consistent regeneration cycles demonstrate strong durability beyond 150,000 km.
The most common issues are DPF clogging, EGR cooler failure, turbo actuator sticking, and CP4 fuel pump wear. These are documented in Jaguar service bulletins and field reports. DPF problems arise from short-trip driving, while EGR and turbo faults are linked to carbon buildup. Fuel pump longevity depends on fuel quality and lubricity.
The DC engine was used in the Jaguar XF (2010–2015), XJ (2010–2015), and XK (2010–2014), primarily in 2.2D and 3.0D variants. It was not used in F-Type or Land Rover models during this period. The engine was factory-fitted only and not offered as a retrofit option for earlier petrol models.
Aftermarket ECU tuning is common on the DC platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
Typical fuel consumption is ~6.0 L/100km (47.1 mpg UK) in combined driving for the XF 2.2D. Highway economy improves to ~5.2 L/100km (54.3 mpg UK). Real-world figures depend on driving style and regeneration frequency. Urban driving with frequent regeneration cycles may increase consumption to ~7.5 L/100km (37.7 mpg UK).
Yes. The DC is an interference design. If the timing chain fails or jumps, piston-to-valve contact is likely, resulting in severe internal damage. While the chain system is robust, preventative maintenance—especially oil changes with correct specification—is essential to avoid catastrophic failure.
Jaguar specifies SAE 5W-30 C3 oil meeting Jaguar TXW-50-001 standard. This low-ash formulation protects the DPF and SCR system from contamination. Oil must be changed every 15,000 km or annually to maintain turbo and chain lubrication. Use of non-compliant oils can lead to DPF blockage and ECU fault conditions.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
