2018 Porsche 911 3.0L Petrol · AF18 TVO

A major suspension failure is the most significant mechanical event recorded for this 2018 Porsche 911, with the off‑side rear coil spring listed as fractured and broken in the 2024 MOT failure. The subsequent 2024 pass shows only tyre condition advisories, and the 2025 and 2026 tests were passed, the latter noting an off‑side rear nail in the tyre. The pattern therefore indicates a single, serious suspension defect that appears to have been remedied, but persistent tyre surface issues that have recurred across several years. The recorded 15,219 mi over eight years works out to roughly 1,900 mi per annum, well below the typical annual mileage for a sports car of this age. Such low utilisation can reduce cumulative wear on engine, transmission and brake components, yet it also means that rubber parts such as tyres and suspension bushings have aged in situ. The recurring tyre advisories—cracking or perishing on both front wheels and a recent nail puncture—are consistent with prolonged storage or limited rotation, and the previous coil‑spring fracture may have been exacerbated by infrequent dynamic loading. When inspecting the rear suspension, feel for any uneven ride height, excessive body roll or clunking noises over bumps that could signal lingering issues with the coil spring mounts or associated dampers. Verify that the replacement spring, if fitted, is correctly seated and that the rear sub‑frame shows no signs of stress cracking. On the tyres, examine the tread depth and sidewall for dry rot, cracks, or bulges, and confirm that the punctured off‑side rear tyre has been repaired or replaced with a tyre of matching specification. Pay particular attention to the front tyres where the advisory for slight damage has persisted; uneven wear or tread separation would be a red flag. A comprehensive pre‑purchase inspection should include a dynamic test ride to assess rear ride quality, steering response and braking performance, even though the MOT history shows no brake or emissions failures. Listen for any squeaks or rattles from the suspension, monitor the pedal feel for any judder, and check that the steering remains centred without pull. Confirm that all tyre pressures are correct and that the wheels are free of corrosion or warped rims. Addressing these specific items will give a clear picture of whether the earlier suspension fault has been fully resolved and whether the tyre condition has been brought back to a safe, road‑worthy state.
