2012 Ford Mondeo 2.0L Diesel · LB12 LJL

A picture of emerging corrosion is the defining mechanical concern in this 2012 Ford Mondeo's recent MOT history, with the 2026 test recording advisories on both rear suspension arms for corrosion not deemed serious enough to fail. The 11 May 2026 outcome also included a failure for the offside steering rack gaiter being missing or no longer preventing the ingress of dirt, a component-level issue that can allow contamination of the rack mechanism and accelerate wear if left unaddressed, though the vehicle subsequently passed the same day once rectified. Prior to 2026 the record is otherwise clean, with consecutive passes from 2021 through 2025 and a single trivial failure for an insecure undertray in March 2025. The shift from a completely advisory-free history to corroded rear suspension components at fourteen years of age is consistent with structural ageing rather than neglect, but it does mark the beginning of a pattern that warrants close physical inspection. Recorded mileage of 39,671 over fourteen years equates to roughly 2,834 miles annually, which is markedly below average for a vehicle of this age and type. The MOT log does not show significant gaps in testing, indicating the car has remained on the road continuously and likely in regular if modest service, though the annual accumulation suggests it has not been used as a primary high-mileage vehicle. Low annual mileage of this nature reduces wear on major drivetrain and braking components but also increases the likelihood of surface corrosion developing on exposed steel items such as suspension arms, subframe mountings, brake lines and exhaust hangers, simply because the vehicle is older and components have had prolonged exposure to the elements. For a prospective buyer, the immediate priority is a hands-on examination of the rear suspension assembly, paying particular attention to the condition of the trailing arms and their mounting points where they bolt to the subframe, as corrosion flagged as not serious today can deteriorate to a structural failure point within a single winter. On a test drive, listen for clonking or knocking from the rear over uneven surfaces and check for any vagueness in the rear suspension response, which could indicate advancing corrosion beyond what was visible to the MOT tester. The steering rack gaiter failure should also prompt a check for any play in the steering, uneven tyre wear across the front pair, and signs of grease or weeping around the rack boots, as a gaiter that has been off the road for any length of time may already have allowed debris into the steering internals. Given the appearance of corrosion advisories at this stage, it would be prudent to inspect the exhaust mounting rubbers, brake pipes along the underbody and the subframe itself for early signs of similar deterioration, as these are typical neighbours to corroding suspension components on a car of this vintage. The brake discs and pads should be examined for surface rust and lipping, as low-mileage cars that do many short journeys can suffer from corroded disc surfaces even when pad material remains adequate. Finally, verify that the steering rack gaiter has been replaced with a proper sealed unit rather than a temporary repair, and confirm there is no recorded advisory history prior to 2026 that might suggest an older corrosion issue previously masked or resolved.
