2015 Porsche Cayenne 3.0L Diesel · SV65 UDM

The Porsche Cayenne’s most recent MOT test on 23 May 2026 at 75,604 miles reveals a stable but borderline roadworthiness status, with the only defect—rear tyres worn close to the legal limit and exhibiting uneven edge wear—indicating a critical consumable failure risk. The previous four tests, all passing without failings, suggest consistent compliance with minor wear thresholds until now. However, the May 2026 advisory on rear tyre condition signals a failure point that, if unaddressed, will escalate into a major safety hazard within the next 1,000–2,000 miles. The absence of structural, suspension, or braking advisories in prior tests implies these systems have not been compromised, though the tyre issue alone warrants immediate attention. The vehicle’s mileage progression of roughly 6,873 miles annually aligns with typical usage patterns for its age, with no abrupt spikes or prolonged stagnation. The most recent 2,293 miles between the May 2025 and May 2026 tests reflect steady operation, and the consistent annual intervals suggest regular driving rather than prolonged storage. There are no gaps exceeding 18 months between tests, which would otherwise raise concerns about deferred maintenance, though the lack of advisories in earlier records means no deferred failures have been documented. A prospective buyer should prioritise an immediate inspection of the rear tyres, verifying tread depth and confirming the cause of edge wear—potentially misalignment or suspension sag. Given the Porsche Cayenne’s age and mileage, the suspension bushes, coil springs, and rear brake calipers should be scrutinised for wear, as these components often degrade incrementally without MOT failings until failure. The absence of corrosion advisories in prior tests is reassuring, but a thorough underbody check for structural rust, particularly around wheel arches and subframes, is essential. The drivetrain and engine bay should also be examined for fluid leaks or degraded hoses, as these are common deferred issues in high-mileage luxury vehicles. The tyre advisory alone justifies caution, but the rest of the MOT history suggests the vehicle has been maintained at a basic level without catastrophic neglect.
