2007 Ford Fiesta 1.6L Diesel · SB57 AAN

Corrosion of the braking system and structural subframes represents the primary mechanical risk for this vehicle, following a failure on 6 December 2025 due to an excessively corroded nearside front brake pipe. While the most recent test resulted in a pass with no defects, the preceding years show a recurring pattern of degradation involving brake lines, subframe integrity, and suspension mounting points. The record indicates a trend of progressive corrosion, moving from advisories regarding pitted brake discs and corroded fuel pipes in 2023 to more significant structural concerns regarding the front and rear subframes in 2024. The vehicle has covered 67,581 miles over its nineteen-year lifespan, averaging approximately 3,557 miles per year. This low annual mileage is significantly below the UK average and suggests the vehicle has spent considerable time stationary or has been used for very short, infrequent trips. Mechanically, this usage pattern often correlates with the types of defects observed in the MOT history, as vehicles that sit for extended periods are more susceptible to surface corrosion on brake discs, the deterioration of rubber components like CV boots, and the seizing of various mechanical linkages. Prospective buyers should pay close attention to the underside of the vehicle, specifically the front and rear subframes and the rear suspension component mounting areas. Although the 2024 advisories noted that the subframe corrosion was not yet seriously weakened, the subsequent failure of the nearside front brake pipe in late 2025 suggests that corrosion is an active issue. During a test drive, it is essential to monitor the steering for any play or vagueness, which could stem from the previously recorded play in the steering rack inner joints, and to listen for any knocking or clunking sounds from the suspension when traversing uneven surfaces or speed bumps. Braking performance must be scrutinised to ensure the recent repairs to the brake pipes have addressed the underlying issue. Listen for any grinding noises or feel for pulsations through the brake pedal, which may indicate that the previously advised pitted and scored brake discs have not been replaced or have deteriorated further. Additionally, check for any uneven pulling to one side during braking or any changes in steering weight, as these could be symptoms of binding calipers or further degradation in the steering and suspension geometry.
