2006 Jaguar XJ 2.7L Diesel · P11 LBA

Chronic suspension wear and emerging structural corrosion define the mechanical history of this vehicle, which has shown a persistent trend of deteriorating rubber components and linkage failures. While the vehicle passed its most recent test on 18 February 2026, this outcome is accompanied by advisories for underbody corrosion across all suspension components and perished tyres. This follows a pattern of failures involving anti-roll bar linkages and track rod end dust covers in late 2025, as well as recurring issues with rear shock absorber bushes dating back to 2017. An average annual accumulation of approximately 5,402 miles is low for a vehicle of this age, suggesting a usage profile characterized by light use or extended periods of standing. A notable gap in the testing record exists between May 2022 and October 2025, a three-year interval that aligns with the recent findings of perished tyre sidewalls and underbody corrosion. Such patterns of inactivity often accelerate the degradation of rubber bushings and promote surface oxidation on exposed chassis components. During a physical inspection, particular attention must be paid to the underbody and suspension mounting points to assess the extent of the recorded corrosion. The history of binding offside rear brakes and recurring play in the steering rack inner joints requires a focused test drive. Listen for knocks or thumps over uneven surfaces, which would indicate the continued wear of the rear shock absorber bushes and radius arm pins. Any steering vagueness or a pull to one side may be linked to the previously flagged track rod and steering rack issues. The repeated failures regarding the bonnet primary retaining device and security mechanisms indicate a persistent fault with the hood latch system that should be physically verified. Additionally, the presence of an oil leak noted in 2018 should be checked for current evidence of seepage around the engine block. Ensure the offside rear brake does not exhibit excessive heat after a drive, as this would suggest the binding issue recorded in 2018 and 2022 has returned.
