2010 Jaguar XJ 3.0L Petrol · OU60 AGV

The vehicle's roadworthiness is currently compromised, showing a worsening maintenance trend characterized by recurring mechanical and emissions failures. The most recent test on 18 June 2026 at 110,747 miles resulted in a failure due to an inoperative engine MIL, multiple exhaust leaks, a faulty seat belt, and tyres with structural damage. This follows a pattern of intermittent failures, including a significant exhaust and brake hose issue in October 2025 and emissions-related failures in September 2024. The frequent recurrence of exhaust leaks and engine management warnings suggests that underlying issues are being patched rather than properly resolved. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 6,900 miles per year. The data shows steady usage over the last decade, moving from 58,260 miles in 2018 to the current 110,747 miles. There are no significant gaps in the record that would suggest long periods of inactivity, which is positive for preventing seal degradation. However, the consistent pattern of failing on consumables like tyres and brake pads suggests that while the car is driven regularly, basic preventative maintenance has been reactive rather than proactive. A prospective buyer must prioritise a thorough inspection of the exhaust system and engine management components. The record shows a persistent history of exhaust leaks and emissions failures, specifically regarding Lambda readings and carbon monoxide levels, which may indicate expensive catalytic converter or sensor issues. The repeated failures of the engine MIL (Malfunction Indicator Lamp) are particularly concerning for a Jaguar of this age, as they can mask more serious engine faults. The suspension and braking systems also require close scrutiny. The 2022 test revealed extensive wear across multiple wishbone bushes and ball joints, and while these appear to have been addressed, the recurring issues with brake pads and corroded brake hoses suggest the braking system is not being maintained to a high standard. Additionally, the history of uneven tyre wear and bald inner edges indicates potential alignment or suspension geometry issues that could lead to further premature component failure.
