2002 Ford Focus 1.6L Petrol · SD52 YDM

A persistent theme of structural and underbody corrosion runs through the MOT history of this 2002 Ford Focus, establishing it as the defining mechanical concern for any prospective buyer. The most recent test on 31 May 2022 recorded a pass but carried multiple advisories flagging corroded rear brake pipes both sides, corroded rear suspension component mountings within the inner and outer sills, corroded rear coil springs, and corroded rear fuel pipes. These advisories mirror concerns raised in earlier years, with nearside and offside outer sill corrosion noted as Major defects at the May 2019 test, where the prescribed areas were deemed excessively corroded and significantly reducing structural strength. Although the 2022 advisories describe the corrosion as not considered excessive, the recurrence of sill, brake pipe, coil spring, and trailing arm bushing deterioration across at least five separate tests from 2017 onwards indicates an ongoing, well-established pattern of underbody oxidation rather than an isolated incident. Mileage accumulation is unusually low for a vehicle of this age, with 80,619 recorded miles over approximately 24 years equating to around 3,359 miles annually. There are notable gaps in the MOT testing record, with no entries between 2017 and the current period being representative of continuous annual testing, and the vehicle appears to have been used sparingly rather than covering substantial distances. Low annual mileage of this nature typically results in reduced wear on high-mileage consumables such as clutch friction material and engine internals, but it does not mitigate corrosion, which progresses regardless of mileage and is often accelerated on vehicles that see short journeys, damp conditions, and infrequent prolonged use. The pattern here suggests underbody exposure to the elements has been the dominant wear factor rather than mechanical fatigue from high usage. From a buyer inspection standpoint, the rear underbody and sill areas should be the primary focus, given the repeated advisories and the 2019 Major defects. A thorough examination should involve checking both inner and outer sills for perforation, particularly where the rear suspension mountings bolt through, and closely inspecting the rear brake pipes along their full length for rust scaling or active leaks, as these were flagged as corroded in four of the recorded tests. The rear coil springs should be examined for surface pitting and cracking, while the trailing arm inner bushes, noted as deteriorated in 2017, 2018, and 2019, should be checked for splitting, cracking, or excessive movement by physically levering the arms with a pry bar or by observing whether the rear axle shifts laterally under acceleration and braking. Given the 2019 Major for an excessively binding nearside front service brake and the 2022 advisory for a leaking nearside rear hydraulic brake cylinder, the brake system warrants a road test with particular attention to any pulling to one side under braking, a soft or sinking pedal, uneven pedal effort, or any need to pump the pedal to maintain effectiveness, all of which could indicate caliper seizure, master cylinder failure, or residual hydraulic fluid loss from corroded pipework. On the road, the buyer should listen for clonking or knocking from the rear suspension over uneven surfaces, which would suggest advanced trailing arm bush deterioration or loose coil spring seats, and should pay attention to any rattling from beneath the vehicle that could indicate exhaust or fuel pipe failure given the 2022 advisory on rear fuel pipe corrosion. The nearside front outer drive shaft CV boot, which was recorded as split at the May 2022 test, should be inspected visually for fresh grease loss and the joint itself rotated by hand to check for any clicking, popping, or binding when steering is applied at low speed. A final check beneath the vehicle with a torch and ideally on a ramp will be essential to confirm whether the corrosion flagged as advisories in 2022 has progressed since, as MOT advisories represent the examiner's judgement on the day and any further deterioration between tests would not be reflected in the record.
