2008 Ford S-MAX 2.0L Diesel · PF08 FPJ

Chronic underbody corrosion and accumulating suspension component wear define the mechanical profile of this 2008 Ford S-Max, with the most recent test on 8 January 2025 returning a pass only after a same-day failure for a seriously weakened offside rear lower suspension arm and insecure headlamp mountings. That failed-to-pass sequence on a single date is significant, as it indicates the structural advisories previously recorded had progressed to a point of major defect on one component within the space of twelve months. The 2024 test also required a re-presentation after failures involving an insecure headlamp, an incompatible LED light source, and a non-functioning front position lamp, suggesting previous attempts at lighting upgrades that did not meet type-approval requirements. Across both 2024 and 2025, advisories for rear sub-frame corrosion, numerous corroded suspension components, worn rear suspension arm pins and bushes, and corroded integral body sills and underside structure all point to a vehicle steadily accumulating age-related structural and chassis deterioration rather than holding a stable roadworthy condition. Recorded mileage stands at 185,898 miles across approximately eighteen years of use, which equates to a roughly typical annual accumulation of 10,328 miles, so usage intensity is not unusual for the age of the vehicle. There is, however, a notable two-year gap between the January 2023 pass and the December 2021 tests, with no MOT recorded for 2022, which may simply reflect the vehicle being either newly registered or untested during that window, or alternatively a period off the road. The mileage progression cannot be fully verified from the records provided, but the consistent year-on-year testing from late 2021 onwards through to January 2025 indicates active use throughout the more recent period. At this overall mileage level, wear on consumables, braking components, clutch, and drivetrain mountings should be expected, but the MOT history itself contains no recorded defects relating to braking or exhaust components. For a prospective buyer, the priority inspection areas must be the rear suspension and underbody structure, given the recurring advisories for sub-frame corrosion, lower suspension arm corrosion, and worn rear trailing arm bushes. On a test drive, listen for clonking or knocking noises from the rear over uneven surfaces, particularly on undulations and speed bumps, and feel for any vagueness or wandering from the rear axle, which would indicate the worn pin or bush movement has progressed beyond the advisory threshold. Visually inspect the rear sub-frame mounting points and lower suspension arms for advanced corrosion, paying particular attention to the offside rear lower arm where the seriously weakened defect was recorded. Examine the sills and underside floor from beneath the vehicle for perforation or bubbling, and check the rear trailing arm bushes by rocking the wheel fore and aft to detect free play. Verify that the headlamp securing mechanisms are properly fixed and that any replacement bulbs or light sources are of a compatible type, as the 2024 failure for an incompatible LED light source suggests previous non-standard modifications were attempted. Finally, confirm that all tyres are of matching size on each axle, as the 2021 failure for mixed rear tyre sizes should not recur, and check the windscreen for any damage that could be argued to impede the driver's view.
