Our Verdict
This 2014 Jaguar XJ diesel is a relatively attractive option for buyers seeking a luxury saloon, supported by a largely clean MOT history and mileage well below the model average. However, buyers should investigate the unexplained fail-then-pass sequence in October 2024 and arrange a thorough pre-purchase inspection before committing.
The most unusual aspect of this vehicle's record is the rapid fail-then-pass sequence in October 2024. The failure on 8 October 2024 at 33,205 miles shows no defects recorded in the data provided, which means the failure category is not visible here, but the fact that a pass was issued only seven days later at 33,266 miles strongly suggests a repair was carried out between tests. Ask the seller for the failure advisory or refusal notice so you can see exactly what caused the initial failure and what was subsequently fixed. A pre-purchase inspection by a specialist familiar with the XJ platform is essential given the complexity and cost of Jaguar parts.
When viewing, check the service history carefully for evidence of regular oil and filter changes on the 3.0-litre V6 diesel, as this engine is sensitive to extended service intervals. Inspect the alloy wheels and bodywork for scuffs and kerbing damage, which are common on low-mileage luxury cars that have been driven predominantly in urban conditions. Also confirm that all electrical systems function correctly, including the infotainment screen, climate control, and adaptive dynamics settings, as electronic faults are a known area of cost on this generation of XJ.
Running a 3.0-litre diesel Jaguar XJ is not a cheap undertaking. Real-world fuel economy typically falls between 35 and 45 mpg depending on driving style, and the vehicle sits in a relatively high insurance group given its value and performance. Road tax for a diesel of this age and engine size is modest under the current bands, but London-area buyers should factor in the ULEZ charge until the vehicle meets the required emissions standard. Annual maintenance costs tend to be higher than for mainstream saloons, with timing belt replacements, brake disc changes, and tyre replacements all commanding premium prices.
Given the top MOT failure reasons across the Jaguar XJ range are suspension arms, headlamps, and tyres, these are the areas to focus on during inspection. Check the front suspension arms and bushes for play or knocking, as these are the most common MOT failure point across nearly 30,000 examples analysed. Inspect both headlamps for condensation, lens cracks, and correct beam pattern, as headlamp-related failures are disproportionately common on this model. Tyres should be examined for even wear across the axle, as inside-edge wear can indicate worn suspension components or alignment issues.
Beyond the model's known weak points, pay close attention to the 3.0-litre diesel engine for any signs of oil consumption, coolant loss, or excessive smoke on startup, which can indicate timing chain stretch or injector wear. Listen for any unusual knocking from the engine on cold start. Check the transmission for smooth changes, as the ZF automatic can develop mechatronic issues if fluid changes have been neglected. Finally, examine the undertrays and sump for any signs of oil leaks, which are common on higher-mileage examples of this engine.
This silver Jaguar XJ (OU14WXF) is a 3.0-litre diesel saloon first registered in March 2014, showing 40,813 miles on its most recent MOT in October 2025. Across five recorded MOT tests spanning 2022 to 2025, the vehicle passed four times with no defects recorded, although one test on 8 October 2024 resulted in a failure that was followed just seven days later by a pass at almost identical mileage. Annual mileage of roughly 5,000 miles sits close to the model average of 4,672, and the MOT pass rate aligns with the 81.6% figure observed across 29,827 Jaguar XJs analysed.
Across 29,827 Jaguar XJs analysed, the model shows an 81.6% MOT pass rate, which is below the all-vehicle average and reflects the brand's reputation for more frequent MOT-related issues than mainstream competitors. Suspension arms, headlamps, and tyres are the most common failure points across the range.

Common Problems: JAGUAR XJ
Known issues reported by owners and MOT testers.
- Air Suspension Failure(Serious)
Air struts leak or the compressor fails to reach pressure, leaving the car "slammed" on its bump stops.
- Door Lock & Window Regulator Failures(Moderate)
The door lock actuators and window regulators are common failure points on the X350. Lock failures can leave doors stuck in the double-locked position, while window regulators fail with the cable-driven mechanism snapping or the motor burning out.
