2010 Jaguar XJ 3.0L Diesel · D9 ULU

The 2010 Jaguar XJ presents a largely stable mechanical picture through its recent MOT record, though the latest test on 2 October 2025 at 207,435 miles introduces a minor but telling concern. Four consecutive clean passes from 2021 through 2024 suggest the car was maintained to a reasonable standard during that window. The 2025 advisory on front tyre condition, worn close to the legal limit on both edges, marks the first recorded defect in five years. This is a consumable item rather than a structural or mechanical failure, yet it hints that basic upkeep may have slipped slightly in the most recent ownership period. The mileage trajectory tells a clear story of sustained high use. Between the July 2022 test at 197,639 miles and the October 2025 test at 207,435 miles, the car covered 9,796 miles across more than three years, a relatively modest pace. However, the earlier stretch from July 2021 at 194,159 miles to July 2022 at 197,639 miles saw only 3,480 miles added, indicating a period of lighter use or possible standing time. The overall average of roughly 12,965 miles per year across its sixteen-year life sits well above typical for a luxury saloon of this age, meaning suspension bushes, brake components, and drivetrain mounts have endured more cycling than a lower-mileage equivalent. A buyer inspecting this car in person should focus on the front suspension and steering geometry. The edge wear pattern flagged on both front tyres in October 2025 points to possible toe misalignment, worn track rod ends, or deteriorated suspension bushes rather than simple underinflation. The rear brakes and handbrake mechanism deserve close attention on a car of this age and mileage, as binding calipers and parking brake linkage wear are common failure points on the XJ platform that do not always surface as advisories until they become outright failures. Structurally, the front subframe mountings, rear spring pans, and inner wing seams should be checked for corrosion, particularly if the car has spent time in a region that uses road salt. The exhaust system, including the catalytic converters and Lambda sensors, warrants a live emissions reading given the mileage, as degraded catalyst efficiency can pass a visual inspection but fail under loaded conditions.
