2013 Porsche Cayenne 3.0L Diesel · LS02 BEL

Structural corrosion on the front and rear sub-frames, alongside deteriorating rear lower suspension arms, defines the current mechanical state of this vehicle. While the test on 11 September 2025 resulted in a pass, the record shows a persistent and widening trend of oxidation across the chassis and suspension linkages that has been flagged since 2024. This pattern of recurring advisories suggests that the underbody is subject to ongoing degradation. The recorded mileage of 90,865 miles is typical for a thirteen-year-old vehicle, averaging approximately 6,990 miles per year. This steady rate of accumulation suggests regular use rather than prolonged periods of stagnation, which generally results in a more predictable wear pattern for drivetrain components and rubber bushings, though it also exposes the underbody to consistent environmental degradation. Particular attention must be paid to the underbody corrosion noted on both the front and rear sub-frames and the rear lower suspension arms. A physical inspection is necessary to determine the extent of the oxidation and whether it is superficial or beginning to compromise the structural integrity of these components. During a test drive, listen for any unusual knocks or clunks when traversing uneven surfaces or during low-speed manoeuvres, as these can be symptoms of deteriorating suspension bushings or weakened linkages. The braking system has a history of wear and pitting on the rear discs, and a previous record from 2022 noted an oil leak from the rear crank seal area. Check for any pedal judder or pulsations during braking, which would indicate warped or heavily pitted discs. Additionally, inspect the ground beneath the rear of the engine bay for fresh oil residue to ascertain if the previously recorded crank seal leak has progressed or been addressed.
