2008 Ford S-MAX 2.0L Diesel · OU08 XVB

The most recent MOT test on 4 March 2026 was a clean pass with no advisories or defects recorded, which is a positive immediate indicator. However, a review of the preceding tests reveals a maintenance trend that has been somewhat inconsistent and is worth careful consideration. The vehicle passed in February 2022 with no advisories, then began accumulating a steady list of advisories related to rear suspension damping, brake wear, and underbody corrosion from 2024 onwards. The February 2025 test, which followed a failed attempt just three days earlier, recorded advisories for reduced rear shock absorber damping, rear brake disc wear, an engine oil leak, and corrosion on underbody suspension components. While the most recent 2026 pass shows no recorded issues, this could indicate either that the previously noted concerns have been resolved or that they have progressed to a point where they no longer warrant advisory status, making physical inspection essential. The fractured nearside front coil spring failure in early 2025 is particularly noteworthy as coil spring failures are typically symptomatic of age-related material fatigue and may suggest the offside spring could be approaching a similar condition. With approximately 109,541 miles recorded over 18 years, this S-MAX has averaged around 6,086 miles per year, which is broadly typical for a vehicle of its age and original purpose as a family MPV. The mileage accumulation appears reasonably consistent, with MOT tests recorded annually since 2022, suggesting the vehicle has remained in regular use rather than being left standing for prolonged periods. This level of usage is generally favourable from a mechanical longevity perspective, as it implies regular fluid circulation, battery charging, and prevention of severe standing corrosion. However, the mileage is now substantial for any vehicle, and components subject to wear per mile, including timing chain components on the 2.0 TDCi engine commonly fitted to this model, dual mass flywheels, clutches, turbochargers, and injectors, will have experienced significant cumulative stress and should be considered for potential replacement or close inspection. The recurring advisories on the rear shock absorbers indicating reduced damping effect across multiple tests from 2024 onwards suggest these units are deteriorating progressively and may now require replacement. On a test drive, pay particular attention to any excessive body roll through corners, a wallowing or floating sensation over undulations, extended stopping distances, or a harsh, bouncy ride quality over minor surface imperfections, all of which would indicate the dampers have reached the end of their service life. The advisory on rear brake disc wear, combined with the noted rear brake pad wear from 2024, suggests the rear braking system may be approaching the point of requiring disc and pad renewal. Listen for any grinding, squealing, or juddering under braking, and check for scoring or lipping on the visible edge of the discs during a physical inspection. The advisory regarding an engine oil leak from the front, although noted as not excessive, should be monitored as oil leaks on the S-Max typically originate from the cam cover gasket, front crankshaft seal, or turbo oil feed and return pipes, all of which can deteriorate further with age. Check the underside of the engine bay for fresh oil residue and inspect the undertray for oil accumulation before a test drive. The underbody and suspension corrosion advisories are consistent with a vehicle of this age, particularly one that may have seen winter road salt exposure, and while not classified as serious at the time, corrosion can progress rapidly. During inspection, pay close attention to suspension arms, subframes, and mounting points, tapping structural components with a suitable tool to detect any flaking or compromised metal. Beyond the MOT history, given the vehicle's age, verify the condition of all tyres for sidewall cracking or perishing even if tread depth is adequate, check the 12V battery for hold-charge capability as batteries typically require replacement every five to seven years, and confirm that brake fluid, coolant, and transmission fluid have been changed in line with manufacturer schedules rather than purely by mileage. Finally, ensure the timing chain and dual mass flywheel have been inspected or replaced where appropriate, as these are known cost items on higher-mileage S-Max diesel models.
