2018 Ford Fiesta 1.5L Diesel · FG18 WPU

The most recent MOT test on 2026-08-08 resulted in a failure, with multiple major defects affecting the vehicle’s lighting systems and structural integrity. This marks a significant deviation from the previous five consecutive MOTs, all of which passed without recorded issues, indicating a potential deterioration in both electrical functionality and mechanical stability. The central rear lower engine mounting failure, in particular, suggests a critical structural weakness that may have developed over time, warranting immediate attention. While the prior MOTs were clean, the sudden onset of these failures raises concerns about underlying wear, poor maintenance, or a latent defect that has now progressed to a point where the vehicle no longer meets roadworthiness standards. The recorded mileage of 117,614 miles for an eight-year-old Ford Fiesta represents a high annual usage rate of approximately 14,702 miles per year, which is unusually aggressive for its age. Such high mileage typically accelerates wear on consumables like brake pads, suspension components, and drivetrain elements, as well as fluid degradation. The absence of significant mileage gaps suggests the vehicle has been in regular, heavy service rather than idling or undergoing prolonged periods of disuse. This pattern increases the likelihood of premature component failure, particularly in areas subjected to repeated stress, such as the suspension, exhaust system, and electrical wiring harnesses. Given the recent MOT failures, the prospective buyer should prioritise a thorough inspection of the near and offside lighting circuits, ensuring all lamps are functional and properly aligned. The central rear lower engine mounting failure indicates a severe structural issue, likely causing excessive movement that compromised the vehicle’s stability. Visually inspect the mounting points for signs of cracking, corrosion, or deformation, and listen for unusual noises during a test drive, particularly when the engine is running at idle or under acceleration, which may reveal vibrations or rattling from loose or damaged mounts. The near and offside stop lamps and rear position lamps failing suggest a common electrical fault, possibly a failing lamp module, wiring harness, or relay. Test each lamp individually by isolating circuits and checking for continuity; if any are non-functional, the underlying cause should be traced to prevent recurrence. Additionally, the 2022 MOT advisory of an offside front coolant leak indicates a potential long-standing issue that may have worsened over time. This leak could lead to overheating if not addressed promptly, so inspect the radiator hoses, coolant reservoir, and water pump for signs of wear, cracks, or leaks. Check the coolant level and condition—old coolant can degrade over time, even with infrequent use—and consider a full flush if the vehicle has been in service for several years. The near-side front tyre showing wear close to the legal limit on the edge suggests uneven tyre wear, which could stem from misalignment, suspension issues, or incorrect wheel balancing. During a test drive, observe tyre contact with the road; uneven wear may indicate steering or suspension problems, and the buyer should ensure the tyres are replaced before they reach the legal minimum tread depth to maintain safety and traction. Finally, given the vehicle’s age and high mileage, a comprehensive mechanical inspection should include checks on the suspension (for worn bushes, broken springs, or binding calipers), brakes (for corrosion, warping, or excessive pad wear), and drivetrain components (for fluid leaks or unusual noises from the transmission or differential). A professional inspection by a qualified mechanic is strongly recommended to assess the full extent of the recent failures and prevent further roadworthiness issues.
