2007 Ford Fiesta 1.4L Petrol · GD07 OGA

The latest MOT test on 26 January 2026 resulted in a pass, but the advisory list indicates a worsening trend in structural and underbody condition. Corrosion-related advisories have escalated from brake pipes and sills in earlier years to a failed test in January 2025 due to significant sill corrosion affecting structural rigidity, followed by recurring advisories for corroded coil springs, fuel pipes, and splitting rear axle bushes. The pattern suggests progressive deterioration in critical areas, particularly the rear subframe, suspension components, and brake system, which demands urgent attention despite the current pass. At 104,792 miles over 19 years, the annual average of approximately 5,500 miles is low for a vehicle of this age, implying prolonged periods of inactivity or very light use. Such a usage profile often leads to age-related degradation rather than wear from high mileage, with standing corrosion, perished rubber components, and seized or binding mechanical parts being more likely than typical high-mileage fatigue. The low mileage does not offset the structural concerns already flagged, but it does highlight the need to scrutinise components prone to deterioration from time rather than distance. A thorough inspection should prioritise the rear sills and integral body structure for corrosion, as the 2025 failure confirms significant weakening that may require professional repair to restore rigidity. The offside rear coil spring and fuel pipes must be checked for advanced corrosion, while the splitting rear axle bushes and distorted offside rear wheel could cause uneven tyre wear, clunking over rough surfaces, or a slight pull to one side. Brake pipes across all wheels have been repeatedly flagged for corrosion since 2022, so inspect for weeping fluid, rust scaling, or grease contamination, and test for a firm pedal without sponginess or excessive travel. The slightly damaged and perishing offside rear tyre should be examined for deep cracks in the sidewall or tread, which increase the risk of a blowout. Additionally, verify the washer system function, as this caused a major failure in 2025, and check the central stop lamp, which has been non-functional in multiple tests. Headlamp lenses should be cleaned to ensure full light output, and the 12V battery health assessed, as low-mileage vehicles often suffer from undercharging or sulphation. Given the age, inspect all rubber hoses, bushes, and seals for perishing, and confirm service history for timely fluid changes, particularly brake fluid, which degrades with age regardless of mileage. A test drive should reveal any suspension knocks, brake judder, or steering vagueness that may indicate worn or corroded components.
