2017 Jaguar XJ 3.0L Diesel · WXT 97

A generally clean MOT record is now tempered by emerging front‑brake wear, as the 27 June 2026 test – which the vehicle passed – recorded fluctuating service‑brake readings on both nearside and offside fronts and noted that each front disc is worn, pitted or scored, though not yet seriously weakened. All preceding six tests from 2020 to 2025 were passed without any recorded defects, indicating a long‑term pattern of roadworthiness that has only recently begun to show the first signs of brake component fatigue. At 77 854 mi the Jaguar XJ averages roughly 8 650 mi per year over its nine‑year life, a mileage rate that sits comfortably within normal usage for a luxury saloon of this age. The MOT history shows no gaps in annual testing, suggesting the odometer readings are consistent and there have been no prolonged periods of inactivity that could mask hidden corrosion or fluid degradation. Mechanically, this mileage level places the vehicle in the mid‑to‑high wear bracket for consumables such as brake pads, discs, suspension bushings and tyre tread, while still leaving ample life for major drivetrain components provided they have been serviced appropriately. When inspecting the brakes, pay particular attention to pedal feel and consistency; a fluctuating service‑brake indication often manifests as a spongy or variable pedal travel, especially under moderate to heavy braking. Listen for any high‑pitched squeal or low‑frequency grinding that could signal worn pads or disc surface damage, and feel for pulsation through the pedal that may point to warped discs. A visual check should confirm that the front discs are not excessively scored and that pad thickness remains within safe limits; given the advisory, anticipate that replacement of pads and possibly discs may be required within the next few thousand miles. Additionally, verify that the brake calipers move freely and that the hydraulic lines show no signs of leakage or corrosion, as these can exacerbate fluctuating brake readings. Beyond the brakes, a thorough pre‑purchase inspection should include a walk‑around for any signs of chassis or subframe corrosion, a check of suspension components for play in the control arms and bushings, and a test‑drive assessment for steering pull, uneven tyre wear or abnormal noises over bumps. While the MOT data does not flag any other defects, confirming the condition of tyres, steering rack, and exhaust system will help ensure that the vehicle’s overall mechanical integrity aligns with its historically clean MOT profile.
