2004 Porsche Cayenne 4.5L Petrol · MAG 100

A persistent theme in the MOT history of this 2004 Porsche Cayenne is the condition of its tyres, with multiple advisories across 2023 and 2024 flagging cracking and perishing on all four corners, and a dangerous failure recorded in October 2025 for an exposed ply or cord on the nearside rear tyre. That dangerous defect, which was rectified just five days later when the vehicle passed a retest, sits alongside a generally clean structural and emissions record across six further tests. Advisories from 2020 also noted worn rear brake discs and thin rear brake pads, suggesting the braking system has required ongoing attention at the rear axle. With the exception of those brake and tyre concerns, the recorded defects are limited, and there is no history of suspension, exhaust, or structural advisories across the seven tests on file. The recorded mileage of 140,261 over roughly 22 years equates to an annual accumulation of around 6,376 miles, which sits in a broadly typical band for a vehicle of this age. There are no extended gaps between tests, indicating the vehicle has remained in continuous use rather than being laid up for prolonged periods, which is generally favourable for avoiding issues such as seized brakes, perished rubber, and flat-spotted tyres. The mileage progression between tests appears consistent with regular, moderate use, though a 22-year-old Porsche with this mileage will inevitably show wear on major mechanical components such as the cooling system, air suspension struts and reservoirs, transfer box, and engine gaskets. The relatively even usage pattern means the advisories are more likely to reflect genuine component wear than neglect during storage. For a prospective buyer, the priority areas to examine are those directly linked to the recorded advisories. A close visual inspection of all four tyres is essential, paying particular attention to the sidewalls and tread for cracking, perishing, bulges, or exposed cords, as the history suggests this has been a recurring issue. The rear brakes should be evaluated for residual wear by checking disc lipping, pad thickness, and caliper slider operation, as a binding or sticking rear caliper is a common fault on higher-mileage Cayennes and would manifest as uneven wear or a pulling sensation under braking. On the test drive, listen for clonks or knocking from the suspension over speed humps and uneven surfaces, which would indicate worn front lower control arm bushes, a known weakness on this platform, and check for any sagging at the rear that could point to fatigued air suspension struts or a leaking reservoir. Finally, inspect the underside for any signs of oil misting around the cam covers, coolant leaks from the front of the engine, and corrosion on the subframes and brake lines, as these are age-related concerns that MOT testing does not always fully expose but are critical to long-term roadworthiness.
