2012 Jaguar XJ 3.0L Diesel · OY12 OXF

The most recent MOT, carried out on 11 May 2026, was passed with a single advisory concerning mild corrosion on the prescribed area of the sub‑frame mounting. Over the eight‑year MOT record the vehicle has consistently passed without any recorded failures, and apart from the 2019 advisories the only other note is this recent, non‑excessive corrosion. This pattern indicates a generally stable maintenance regime with no evidence of deteriorating safety‑critical items, although the recurring advisories suggest that some wear items have been allowed to approach the legal limits rather than being proactively renewed. At 110,059 miles the Jaguar XJ averages roughly 7,800 miles per year, which is modest for a 14‑year‑old executive saloon. The mileage is neither unusually low nor excessive, implying the car has not spent prolonged periods idle for the majority of its life, but the relatively low annual distance also means that many components may have aged more by calendar time than by use. Consequently, parts such as rubber bushings, seals and tyre sidewalls are likely to have experienced ageing‑related degradation even if they have not been heavily stressed by mileage. When inspecting the vehicle the buyer should give particular attention to the front and rear tyre condition, as the 2019 advisory noted edge‑wear on both off‑side tyres. Look for uneven tread depth, sidewall cracking or bulging, and listen for a hollow thump when the tyre is rolled under load, which can indicate internal separation. The brake discs were flagged as worn and pitted in 2019; while they were not deemed unsafe at the time, any pulsation or shudder through the pedal, especially under hard braking, may signal that the discs have progressed beyond acceptable limits and will require resurfacing or replacement. The sub‑frame corrosion advisory, though described as not excessive, warrants a visual inspection for any flaking or rust that could compromise mounting points; any looseness or creaking from the rear suspension during cornering would be a symptom of advancing corrosion affecting structural rigidity. Given the car’s age, a thorough calendar‑based check is advisable regardless of mileage. Examine all tyre sidewalls for age‑related cracking, as tyres over six years can deteriorate even with low wear. Verify the 12 V battery’s cranking voltage and check for any sulphation, especially if the vehicle has been stored for extended periods. Inspect the suspension bushes, ball joints and coil springs for signs of dry rot, cracking or excessive play, and ensure the steering rack and tie‑rod ends are free of binding. Confirm that engine oil, coolant, brake fluid and power‑steering fluid have been changed in accordance with the manufacturer’s time‑interval recommendations, as fluids can degrade and lose effectiveness even on low‑mileage cars. Finally, review the service book for regular oil changes, filter replacements and any recorded major services; a complete and up‑to‑date service history will reinforce confidence in the vehicle’s overall mechanical soundness.
