2021 Porsche Cayenne 2.9L Petrol · SW21 AWM

The latest DVSA MOT test for this 2021 Porsche Cayenne was conducted on 2025-11-06 and resulted in a pass, though it included an advisory regarding the rear brake pads, which are noted to be wearing thin to a level of 1.1.13 (a) (ii). This advisory is not a failure but indicates that the brake pads will require replacement within the next few months to maintain safe braking performance and prevent excessive wear to the backing plates or potential damage to the brake discs. The previous MOT tests in October 2024 and February 2024 both showed no defects, suggesting a stable maintenance record up to that point. The presence of this single advisory over the past year, however, does warrant closer attention to the braking system, particularly the rear assembly, to avoid compounding issues such as uneven wear, reduced braking efficiency, or even binding calipers from prolonged pad wear. The recorded mileage of 48,591 miles for a vehicle aged five years represents a reasonable annual usage rate of approximately 9,718 miles per annum, which is consistent with typical driving patterns for a high-performance vehicle of this class. This level of mileage suggests moderate to active use, which can accelerate wear on consumables like brake pads, suspension components, and fluid systems. However, the absence of significant mileage gaps—such as long periods of inactivity—does not necessarily imply excessive stress on the drivetrain or structural integrity, though prolonged standing without fluid movement could theoretically lead to minor corrosion or fluid degradation over time. The consistent mileage accumulation does mean that consumables like brake pads, filters, and fluids should be monitored more closely, as higher mileage often correlates with faster depletion rates. Given the advisory on rear brake pad wear, the prospective buyer should conduct a thorough inspection of the braking system, focusing on the rear calipers and discs for signs of uneven wear, corrosion, or binding. During a test drive, listen for any unusual grinding noises when applying the brakes, which could indicate pad-to-disc contact or caliper binding. Additionally, check for a reduction in braking performance, particularly at higher speeds or when braking from a stop, which may signal that the pads are nearing the end of their effective life. Inspect the rear brake pads visually for thickness and condition, ensuring they are not glazed or warped, and measure their remaining thickness against the manufacturer’s specifications. If the pads are indeed thin and the advisory remains unresolved, replacement should be prioritised to prevent further damage to the backing plates or discs. Beyond the braking system, the buyer should also assess the vehicle’s suspension and fluid condition. Given the vehicle’s age and mileage, inspect the suspension components for signs of wear, such as cracked or seized coil springs, damaged suspension bushes, or excessive play in the struts or control arms. Listen for clunking noises during cornering or over bumps, which may indicate worn suspension bushings or damaged spring mounts. Check the fluid levels in the brake, coolant, and differential systems, ensuring they are topped up and free from contamination. Given the vehicle’s performance-oriented nature, the differential fluid should be replaced according to the manufacturer’s recommendations, typically every 60,000 to 100,000 miles or every two years, whichever comes first. Finally, verify that the service history includes scheduled maintenance such as oil changes, timing belt replacement (if applicable), and exhaust system inspections, as these are critical for long-term reliability. For the tyres, given the age of the vehicle, check for sidewall cracking or perishing, which can compromise structural integrity and safety, even if the tread depth is adequate.
