2010 Jaguar XJ 3.0L Diesel · SM10 AAK

The most recent MOT test on the 2010 Jaguar XJ took place on 2024-03-07, resulting in a passing outcome with two advisories related to tyre wear that approached the legal limit—specifically, the offside and nearside rear tyres showing significant lateral wear patterns indicative of uneven loading or alignment issues. This follows a pattern of fluctuating MOT results, with two prior failures in 2022 and 2023, where major defects were identified in critical components such as rear anti-roll bar ball joints, brake discs, and front suspension arms. While the 2024 test cleared the vehicle, the recurring issues in suspension and braking systems suggest a history of wear progression that may require closer attention, particularly if the vehicle is driven regularly. The presence of multiple advisories—particularly those tied to tyre and suspension wear—also indicates that the vehicle has not been maintained to the same level of precision as a newer or lower-mileage model, warranting a thorough inspection before purchase to mitigate potential long-term reliability risks. The recorded mileage of 97,236 miles for a 2010 XJ represents a moderate annual usage rate of approximately 6,077 miles per year, which is within the expected range for a vehicle of this age and class. However, the mileage data alone does not fully capture the vehicle’s operational profile, as the gap between 2022 and 2024—over two years without an MOT—could imply periods of prolonged standing, which often accelerates wear on components like brakes, suspension, and seals due to corrosion and fluid degradation. The front tyres failed the 2022 MOT with tread depths below the legal minimum, a common issue for vehicles that have been stationary for extended periods, as standing can cause brake dust accumulation and uneven wear. This further underscores the need for a detailed inspection, particularly focusing on the braking system, as standing can also lead to brake disc corrosion or binding calipers, which may not be immediately apparent but could compromise stopping performance. Given the MOT history and the vehicle’s age and mileage, the buyer should conduct a meticulous pre-purchase inspection to address the known and suspected issues. The rear tyre wear advisories from 2024 suggest that the vehicle may have been subjected to misalignment or incorrect load distribution, leading to lateral wear. During a test drive, check for uneven tyre wear patterns, particularly on the shoulders or edges of the tread, which may indicate alignment or suspension misalignment. Listen for unusual noises from the suspension, such as clunking or rattling, especially when driving over bumps, as this could signal worn ball joints or suspension arm pins. The major failures from 2023—particularly the excessively worn anti-roll bar ball joints and brake discs—highlight the need to inspect these components for further deterioration. Inspect the brake discs for deep grooves, warping, or corrosion, and listen for a grinding noise when applying the brakes, which could indicate worn brake pads or metal-on-metal contact. Additionally, verify that the brake fluid is clear and free of contamination, as standing fluid can degrade over time, leading to reduced braking efficiency. For the 2010 XJ’s age and mileage, the buyer should also assess the vehicle’s overall structural integrity and fluid condition. Given the vehicle’s age, inspect the tyres for signs of sidewall perishing or cracking, which can occur due to prolonged exposure to UV light and temperature fluctuations. Check the 12-volt battery for signs of corrosion on the terminals and ensure it holds a charge when cold cranking amps (CCA) are tested, as older batteries may struggle to provide sufficient power for modern electrical systems. The suspension should be examined for signs of corrosion in the control arms, bushes, or struts, particularly in the rear where the 2023 MOT flagged issues. Inspect the exhaust system for leaks or corrosion, as emissions-related advisories from past MOTs may indicate catalytic converter or oxygen sensor wear. Finally, verify that the service history is up to date, particularly for fluid changes—oil, brake fluid, coolant, and transmission fluid—since these should be replaced at specified intervals, even if the vehicle has not been driven extensively. If the vehicle has been stored for long periods, consider a comprehensive fluid flush to prevent sludge buildup and ensure long-term reliability.
