2013 Porsche Cayenne 3.0L Diesel · LS02 BEL

The 2013 Porsche Cayenne presents a stable but structurally weathered mechanical picture as of its most recent MOT on 11 September 2025 at 90,865 miles. The vehicle passed, yet the tester flagged corrosion on both rear lower suspension arms and the rear sub-frame, each noted as not seriously weakened. A single inoperative nearside rear registration plate lamp was also recorded. Comparing this to the 2024 pass at 83,249 miles, the same rear suspension arm and sub-frame corrosion advisories persist, indicating surface corrosion has been present for at least two years without structural deterioration. The 2024 test also recorded worn rear sub-frame bushes on both sides and worn rear brake discs, items that did not reappear in 2025, suggesting they may have been addressed or that wear has not yet reached advisory thresholds again. The 2024 failure at 83,246 miles for a defective electronic parking brake, worn nearside rear brake pads below 1.5 mm, a brake fluid warning lamp, and a failed nearside headlamp dipped beam shows that critical safety systems were neglected at that point, though these were evidently rectified before the retest two days later. The mileage progression is consistent and unremarkable for a thirteen-year-old vehicle. From 62,049 miles on 28 July 2022 to 75,891 miles on 14 September 2023, the vehicle covered 13,842 miles in just over twelve months. The following year saw 7,358 miles added between September 2023 and September 2024, and then a minimal 7,616 miles between September 2024 and September 2025. The final interval is notably low at roughly 1,600 miles if annualised from the last test, suggesting either a change in ownership pattern or reduced use. There are no glaring gaps in the MOT record that would indicate long-term storage or clocking concerns, and the annual testing pattern is regular. A buyer should focus the physical inspection on the rear sub-frame and suspension mounting points. The repeated advisories for corrosion on the rear sub-frame and both rear lower suspension arms across multiple tests point to an environment or usage pattern that promotes underbody rust. While testers have consistently judged the corrosion not seriously weakened, any visible scaling, flaking, or soft spots around the sub-frame mounting points and lower arm attachment areas warrant a thorough check with a torch and probe. The rear brake discs have appeared as worn in both 2022 and 2024, so pad and disc thickness at the rear should be measured, and the rear calipers checked for binding given the history of uneven wear. The electronic parking brake fault in 2024, though resolved, means the parking brake function should be tested on an incline and the actuator inspected for sluggance or noise. The oil leak noted at the rear crank seal area in 2022 did not reappear in subsequent tests, but the engine and gearbox underside should still be examined for fresh weeping. Finally, the headlamp aim and function should be verified, as a dipped beam failure was recorded in 2024 and headlamp alignment issues can recur on vehicles with suspension wear.
