2012 Ford Fiesta 1.4L Diesel · SP12 XOY

Corrosion across the underbody and structural components represents the primary mechanical risk for this vehicle, with a consistent pattern of advisories regarding the front subframe, fuel pipes, and various suspension mounting areas. While the 2025-10-15 test resulted in a pass, the record shows a recurring trend of degradation, including a major failure in October 2024 due to an exhaust leak and emissions issues, and a failure in October 2025 concerning excessively worn offside rear axle swivel pins and bushes. The presence of surface corrosion on the fuel pipes and subframe, alongside previous advisories for corroded suspension spring mountings and rear axle components, indicates an ongoing progression of oxidation throughout the chassis and running gear. The vehicle has covered 80,755 miles over its 14-year lifespan, which equates to an average annual accumulation of approximately 5,768 miles. This is a low mileage profile for a vehicle of this age. While lower mileage typically implies less wear on drivetrain components, it can also correlate with the observed corrosion issues, as vehicles covering fewer miles may spend more time stationary or in environments where road salt and moisture are not cleared by regular driving. The mechanical wear documented in the MOT history, specifically regarding the axle bushes and track rod ends, suggests that despite the low mileage, the rubber and metal components are reaching the end of their service life. Prospective buyers should pay close attention to the condition of the suspension and steering linkages during a test drive. The recent history of track rod end play and worn axle swivel pins and bushes means you should listen for knocking or clunking sounds when driving over uneven surfaces or speed bumps. Any wandering sensation in the steering or a tendency for the vehicle to pull to one side could indicate that the previously flagged track rod end or suspension bush issues have not been fully resolved or have recurred. Additionally, the advisory regarding a slight bind on the offside front wheel suggests checking for uneven brake wear or a sticking caliper, which may manifest as a pulling sensation under braking or heat radiating from that specific wheel. The documented corrosion on the front subframe and fuel pipes necessitates a thorough visual inspection of the underside to determine the depth of the oxidation. While the 2025 advisory noted the subframe was not seriously weakened, the presence of corrosion on fuel lines is a specific point of interest for safety. During the inspection, check for any signs of weeping or degradation in the fuel delivery system. Given the previous failure regarding the exhaust back box being unattached, ensure the entire exhaust system is securely mounted and that there are no audible leaks or excessive vibration from the engine bay or under the floor, which would indicate the previous emissions and exhaust issues have been addressed.
