2004 Porsche Cayenne Tiptronic S 3.2L Petrol · MX54 MTY

The vehicle is in a state of significant decline following a failed MOT test on 15 May 2026 at 186,635 miles. This recent failure reveals a critical escalation in structural issues, as the tester identified excessive corrosion on the suspension component mounting areas across both the nearside and offside front, and the nearside rear, which significantly reduces the structural strength of the sills. Furthermore, the vehicle failed on an inoperative engine management light and exhaust leaks that prevented emissions testing from being completed. These faults suggest that fundamental mechanical and structural maintenance has not been prioritised despite the previous 2025 failure. At 186,635 miles over 22 years, the Cayenne has averaged approximately 8,500 miles per year, which is consistent with typical usage for its age. However, the record shows a worsening trend in hardware and structural integrity. While the September 2023 test at 178,607 miles noted only minor exhaust leaks and slightly deteriorated brake hoses, the 2025 and 2026 tests show rapid degradation of brake pipes and structural metal components. The transition from minor corrosion in 2023 to significant structural strength loss in 2026 indicates that the chassis is reaching a terminal stage of advanced oxidation. Immediate attention is required for the chassiswork and braking system. The 2026 test also flagged multiple lighting failures, including both headlamps and stop lamps, alongside a nearside rear tyre below the legal tread depth limit. The presence of excessive corrosion on both front brake pipes and pitted inner brake discs suggests that the braking system requires a comprehensive overhaul for safety. Given the structural damage reported to the sills and mounting points, the vehicle represents a high risk for a prospective buyer, as the cost to rectify structural rust often exceeds the market value of an older vehicle.
