2009 Porsche Cayenne 3.0L Diesel · SH59 OTV

The vehicle is currently roadworthy, but the maintenance history reveals a significant decline in structural and mechanical condition recently. While the most recent test in October 2024 at 164,331 miles passed with no defects, this followed a problematic period in 2023 where extensive advisories and a failure occurred. The trend suggests a shift from a historically clean record to a phase of accelerated corrosion and component wear, though the current owner appears to have addressed the issues flagged in mid-2023. At 17 years old, the recorded 164,331 miles represent an average annual usage of approximately 9,600 miles, which is consistent with typical UK driving patterns for this age. However, the interval between June 2022 and June 2023 saw nearly 10,000 miles driven, during which the vehicle suffered its most significant mechanical failures. The gap between the last MOT in October 2024 and today's date is nearly nine months, meaning the vehicle is still operating within its valid test period since the last professional inspection. The 2023 inspection records at 160,372 miles highlighted widespread corrosion across the chassis and suspension. The tester identified corroded Macpherson struts, sub-frame mounting points, and fuel tank straps. While these were noted as not seriously weakened at the time, the presence of multiple corroded brake pipes and steering hoses indicates a high risk of fluid-related failures. A buyer should specifically inspect for further degradation of the sub-frame, as the previous records showed recurring rust in these structural areas over several years. Suspension components have also shown signs of fatigue, with worn upper arm bushes and corroded coil springs noted in 2023. The parking brake efficiency was also described as just meeting the requirement during that period, suggesting the system is nearing the limit of its adjustment range. Given the history of sub-frame bush failures back to 2013, a thorough check of the current structural integrity and rubber bushings is essential to ensure the corrosion has not progressed since the 2024 pass.
