2005 Ford Fiesta 1.2L Petrol · GV55 OGC

Corrosion of the rear sub-frame and brake pipes represents the primary mechanical concern for this vehicle, as these issues have persisted or emerged in recent testing cycles. The most recent MOT on 27 February 2026 confirms that the rear sub-frame is corroded and both rear brake pipes are showing signs of corrosion, though they are currently covered in grease or similar material. This follows a pattern of recurring advisories regarding brake pipe corrosion and exhaust leaks noted in 2024 and 2025, alongside a previously recorded failure for a binding nearside front service brake in 2022. While the vehicle has passed its latest inspection, the trend indicates an increasing number of advisories related to structural and fluid containment components. The recorded mileage of 114,806 miles over a 21-year lifespan equates to an average annual accumulation of approximately 5,467 miles. This is a low rate of usage for a vehicle of this age, which can often lead to specific mechanical vulnerabilities. Low-mileage vehicles are frequently subject to more frequent thermal cycles and longer periods of inactivity, which can contribute to the degradation of rubber components, such as the tyre perishing and anti-roll bar linkage dust cover deterioration noted in previous tests. Furthermore, the low annual mileage does not preclude the development of corrosion, as evidenced by the current state of the sub-frame and brake lines. A prospective buyer should pay close attention to the underside of the vehicle during a test drive, specifically looking for signs of active fluid leaks or excessive rust. The 2026 advisory regarding an oil leak, while described as not excessive, necessitates a close inspection of the engine and transmission seals to ensure it is not worsening. Additionally, the 2025 advisory regarding power steering seepage on the offside front component should be verified to ensure there is no significant loss of hydraulic pressure or visible pooling. During the drive, listen for any knocking or clunking sounds from the rear suspension, which could indicate that the sub-frame corrosion is progressing beyond surface level, or any pulling to one side that might suggest issues with the previously noted brake binding or steering components. Specific attention must also be given to the braking system and exhaust. Given the history of corroded brake pipes and worn front brake discs, the pedal feel should be checked for any sponginess or pulsation, which could indicate air in the system or uneven disc surfaces. The minor exhaust leak noted in 2024 should be checked for any changes in exhaust note or smell within the cabin. Because the rear sub-frame and brake lines are flagged for corrosion, it is essential to confirm whether the grease applied to the pipes is a temporary measure or part of a preventative approach, as the structural integrity of these components is vital for long-term roadworthiness.
