2007 Ford Fiesta 1.4L Diesel · FN57 HNF

A nineteen year old Ford Fiesta carrying over 134,000 miles presents a brake pipe corrosion pattern that dominates its recent MOT history and should be the primary mechanical concern for any prospective buyer. Across five of the six tests on record, the brake pipework has attracted advisories or failures, beginning with a 2020 advisory on the offside rear pipe, escalating through 2021 when all brake pipes were noted as corroded though coated, and culminating in a Major failure on 8 January 2022 due to an excessively corroded offside rear brake pipe. By the February 2022 retest, three pipes were again flagged as corroded and an offside front coil spring was added to the list, indicating that the corrosion is systemic rather than isolated to a single section of line. The January 2023 test returned a clean pass with no advisories, but brake pipe corrosion of this persistence on a Fiesta of this age is unlikely to have resolved itself; it is far more probable that the lines were replaced between tests and that the underlying corrosion on surrounding underbody metal remains. This chronic brake pipe issue sits alongside a separate engine oil leak narrative, first recorded as borderline in 2021, escalating to a Major failure for excessive leakage in January 2022, and then not recurring on the record, suggesting either repair or partial sealing between tests. The annual mileage accumulation of roughly 7,000 miles is broadly typical for a car of this vintage, and the testing record shows reasonably consistent annual contact with the MOT station from 2017 through 2023, indicating the vehicle has remained in regular use rather than being laid up for extended periods. There is a gap between the January 2020 test and the December 2018 test, and another between February 2023 and the prior January 2022 test, but neither interval exceeds fifteen months and both are consistent with normal SORN or post-test timing rather than long-term storage. The steady accumulation across nineteen years suggests consistent mechanical loading on the engine, transmission, brakes, and suspension, which combined with the high absolute mileage means consumable wear items such as dampers, bushes, clutch, and engine internal components will be correspondingly aged. For a prospective buyer, the brake pipe corrosion history warrants a thorough physical inspection of the entire underbody brake line circuit, including the rear axle lines, four-way unions, and sections running along the chassis rails, as corrosion frequently develops at bends and clip fixings before becoming visible on straight sections. It is also prudent to check for any signs of recent brake fluid leakage beneath the car or a low fluid level in the reservoir, which could indicate that a corroded section has been replaced and is now weeping at a joint. Given the oil leak that progressed from advisory to Major in 2022, the engine bay should be inspected for fresh oil residue on the block, sump, and cam cover, and the underside examined for drips on the subframe and exhaust shielding. During a test drive, listen for any brake pedal sponginess or excessive travel, as air ingress from a weeping seal during pipe replacement can mimic this, and feel for pulling under braking which would suggest a seized caliper or a hydraulic restriction in a corroded pipe. The coil spring corrosion advisory from February 2022 is another area demanding close attention on a vehicle of this age and mileage, particularly as Ford Fiesta front springs are known to fracture once surface corrosion has compromised the steel. With the engine off and the car on level ground, push down firmly on each front corner and release; a secondary thud or inconsistent damping return suggests a weakened or broken spring. The recorded front brake disc pitting from 2017 and 2020, combined with the 2017 tyre cut failure and twisted brake hose finding, points to a front end that has seen regular kerb or pothole contact, so check both front tyres for uneven inner or outer shoulder wear which would indicate alignment or suspension component wear. Finally, the 2017 position lamp failure is a minor electrical item, but on a Fiesta of this age the multi-plug connections to the front light units often become brittle, so verify that all front and rear lighting functions are reliable and that no warning lights remain illuminated on the dashboard before committing to purchase.
