2015 Jaguar XJ 3.0L Diesel · BC15 YBE

The vehicle's roadworthiness is currently compromised by emerging structural and corrosion issues, indicating a worsening maintenance trend. While the car passed its most recent MOT on 3 February 2026 at 141,718 miles, the tester flagged significant corrosion on both rear fuel tank straps and the rear sub-frame. The inspector also advised that the exhaust is corroded at the rear. These findings follow a failure on 2 February 2026 involving a perished nearside rear tie bar outer dust cover, suggesting that the vehicle's underbody is increasingly susceptible to environmental degradation. The mileage profile shows consistent, heavy usage, averaging approximately 12,883 miles per year. The data shows a steady climb from 48,048 miles in July 2018 to the current 141,718 miles. Between February 2025 and February 2026, the vehicle covered 10,534 miles. This high annual mileage places significant stress on mechanical components and consumables. The record shows a pattern of neglecting basic upkeep, evidenced by repeated failures for worn tyres, such as in July 2019 and February 2024, and inoperative lighting in July 2018. A prospective buyer must conduct a thorough underside inspection to assess the extent of the sub-frame and fuel strap corrosion. The transition from minor suspension component failures, like the compliance arm bushes in February 2025, to structural corrosion in 2026 suggests the vehicle is entering a phase of more expensive repairs. You should specifically check the integrity of the exhaust system and the mounting points for the fuel tank. The suspension history also warrants attention. The tester identified issues with the nearside rear track control arm in February 2024 and compliance arm bushes in February 2025. Given the high mileage and the recent reports of corrosion, the condition of all suspension bushes, ball joints, and mounting hardware should be verified to ensure the chassis remains structurally sound and the ride quality is not compromised by excessive play in the steering or suspension geometry.
