2013 Jaguar XJ 3.0L Diesel · G24 SAX

Recurring advisories regarding exhaust integrity and tyre wear patterns suggest a vehicle that requires focused attention on its consumables and structural underpinnings. The most recent MOT test on 11 March 2026 resulted in a pass, yet it highlighted a persistent minor exhaust gas leak on the offside front and the onset of corrosion on the rear sub-frame. While the vehicle has maintained a consistent pass rate over the last six years, the re-emergence of exhaust-related advisories and the new notation regarding sub-frame condition indicate that the mechanical profile is shifting from a period of stability toward one requiring proactive component replacement. Accumulating 92,930 miles over thirteen years results in an average of approximately 7,148 miles per annum, which places this Jaguar XJ within a standard usage bracket for its age. This rate of mileage suggests the vehicle has been in regular operation rather than subjected to prolonged periods of inactivity, which typically benefits complex electronic and hydraulic systems. However, the consistent history of tyre-related advisories—specifically those noting uneven wear on the edges—points to potential alignment sensitivities or suspension geometry issues that often manifest in vehicles of this weight and complexity as they reach this mileage milestone. Prospective buyers should prioritise a thorough inspection of the rear sub-frame, as the recent advisory confirms the presence of corrosion. During a test drive, listen for any metallic grinding or creaking noises from the rear axle when navigating uneven road surfaces, which could indicate that this corrosion is affecting the mounting points or associated suspension bushes. Furthermore, the persistent exhaust leak on the offside front should be investigated for signs of blowing or soot deposits in the engine bay, as this can lead to increased cabin noise and potential sensor interference if left unaddressed. The noted uneven tyre wear on both the front and rear axles warrants a professional four-wheel alignment check to ensure the suspension geometry is within factory specifications. On the road, pay close attention to the steering response; any tendency for the vehicle to pull to one side or any vibration felt through the steering wheel at motorway speeds may indicate that the tyres are not the only factor contributing to the uneven wear. Ensure the test drive includes a variety of speeds to confirm that the suspension remains composed and that no knocking sounds are present, as the combination of sub-frame corrosion and tyre wear patterns can often mask underlying issues with control arm bushings or ball joints.
