2016 Porsche Macan 3.0L Diesel · N26 BAX

A clear pattern of rear suspension corrosion defines the mechanical profile of this 2016 Porsche Macan across its MOT history. The most recent test on 10 November 2025 recorded an advisory for both rear coil springs showing corrosion, the same component that was flagged at the 6 November 2024 inspection. This repeat advisory indicates a progressive deterioration rather than a one-off observation, suggesting the springs have lost protective coating integrity and the surface oxidation is advancing into the metal. Aside from a minor defect relating to the offside rear outer stop lamp lens and two advisories for child seats preventing full inspection of the rear adult belts, the November 2025 outcome was a pass with no failures recorded across the entire documented history. The vehicle has not been presented for test with any advisory-free result since November 2022, when the last fully clean pass was issued. Annual mileage accumulation of approximately 9,788 miles per year sits close to the expected average for a ten-year-old vehicle, indicating regular use rather than long stationary periods. The recorded tests run consecutively each November from 2019 through 2025, with no gaps in the documentation, confirming the vehicle has remained in active road use and on the public road throughout this period. Mileage progression between tests appears broadly linear and consistent with the stated annual rate, which should mean normal wear rates on engine, transmission, and drivetrain components without the elevated consumption typically seen on high-mileage examples. The continuity of testing also confirms the vehicle has not been off the road for extended lay-up, which removes concerns about seized callipers, perished rubber, and flat-spotted tyres that often accompany long periods of inactivity. Given the recurring rear coil spring corrosion advisory, a prospective buyer should carry out a physical inspection of the springs for advanced scaling, flaking, and any loss of coil cross-section, as the MOT advisory represents only a baseline observation and springs can deteriorate significantly between annual tests. The test drive should include firm pressing of the rear suspension over speed humps and uneven road surfaces to listen for knocking or clonking noises that would indicate the corroded springs have begun to compromise the spring seats or neighbouring mounting areas. Additionally, the rear brake pad advisory from 2024 alongside the front brake pad advisory from the same test suggests consumable wear was approaching replacement thresholds, so a thorough check of current pad thickness and disc condition on all four corners is warranted, with particular attention to any binding or uneven wear on the rear callipers given the Macan's known sensitivity to slide pin corrosion. The 2024 advisories also recorded both rear tyres worn to 3mm on the edges, indicating either an alignment issue or consistent shoulder loading; a buyer should verify current tyre condition and check for uneven shoulder wear that might point to a developing geometry problem. Undertrays and engine covers have been noted at multiple tests as obscuring inspection of underlying components, meaning oil leaks, CV joint gaiters, and exhaust condition cannot be fully verified through MOT data alone, so a raised inspection with the undertrays removed is essential to check for oil weeps from the sump, transfer case, and rear differential area. The stop lamp lens defect on the offside rear should be verified as purely cosmetic, with confirmation that the lamp still illuminates correctly and that no water ingress has affected the bulb holder. Beyond these documented items, an extended road test should focus on PDK gearshift quality, any vibrations through the steering or driveline at speed, and a scan for any warning lights on the instrument cluster, as MOT records cannot establish the mechanical integrity of electronic systems, turbocharger function, or oil consumption trends specific to this powertrain.
