2018 Porsche Cayenne 3.0L Diesel · RY18 AOU

The most recent MOT, carried out on 4 March 2026, was passed with no recorded defects, indicating that the vehicle presently meets the statutory safety standards. However, the preceding test on 23 February 2026 recorded a major failure of the off‑side front coil spring, a critical suspension component, and earlier years show a pattern of tyre‑related advisories and brake‑pad wear warnings. The sequence suggests that the car has required intermittent corrective work, but the latest clean result points to recent remedial action having restored the primary safety items, although the history of recurring tyre and brake wear signals that the maintenance regime has been reactive rather than proactively preventive. At 88 556 miles on the odometer, the Cayenne averages just over 11 000 miles per annum, which is within the normal usage envelope for a performance SUV of its age. The mileage does not indicate any periods of prolonged inactivity that might predispose the vehicle to age‑related degradation such as rubber perishing or battery sulphation, nor does it suggest excessive short‑trip abuse that could accelerate clutch or transmission wear. Nevertheless, the cumulative distance means that wear items such as suspension bushings, engine mounts, and drivetrain fluids will have approached the typical service intervals and should be inspected for signs of fatigue or contamination. When inspecting the vehicle, give particular attention to the off‑side front suspension where the coil spring was previously fractured; verify that the replacement spring is correctly fitted, that the associated damper shows no oil leakage, and that the mounting points and bushings are free of corrosion or play. Examine all four tyres for uneven tread wear, sidewall cracking, or cuts, especially the near‑side front tyre that was noted as close to the legal limit and the off‑side rear tyre that previously exposed ply; any vibration, thumping, or pulling to one side during a short drive could indicate lingering tyre or alignment issues. The brake pads were flagged as near the wear limit in early 2023, so check the pad thickness and inspect the discs for scoring or glazing; any pulsation or shudder when applying the brakes warrants immediate attention. Also confirm that the wiper blades have been replaced since the 2021 defect, as a defective blade can compromise visibility in adverse weather. Given the vehicle’s eight‑year age, a thorough audit of time‑based components is advisable. Inspect the 12‑volt battery for terminal corrosion and test its cranking voltage, as batteries can lose capacity even with moderate use. Verify that the coolant, brake fluid, and gearbox oil have been changed within the manufacturers’ recommended intervals, looking for signs of moisture ingress or sludge. Check for any rust on the chassis, especially around the wheel arches and suspension mounting points, which can be exacerbated by standing periods. Finally, ensure the service book is up‑to‑date with stamps for major services such as timing‑chain or belt replacements, as these are critical to the long‑term reliability of a high‑performance Porsche.
