2014 Ford Fiesta 1.5L Diesel · FL14 ACF

The most recent DVSA test on 22 April 2026 resulted in a pass, but the outcome should be interpreted with caution because the vehicle failed the same checks just one day earlier on 21 April 2026. The earlier failure cited headlamp aim being too high on both sides, an exhaust emission reading exceeding the manufacturer's specified limit, and a minor defect for an inoperative registration plate lamp. These were rectified and the vehicle returned the next day for a pass, although the headlamp adjustment and lamp defect may suggest underlying electrical or alignment issues that could readily reoccur. Advisories recorded alongside the latest pass include a nail in the offside rear tyre, a smooth brake pedal, damaged diesel particulate filter sensors at the front, and a chip in the front windscreen within zone B. The two earlier passes in 2025 and 2024 were entirely clean of advisories, so the recent cluster of minor and advisory items suggests a slight worsening of condition, particularly regarding emissions, lighting, and brake feel. With 177,457 miles recorded over approximately twelve years, this Fiesta has covered an average of around 14,800 miles annually, which is well above the typical UK usage for a supermini. This is consistent with predominantly motorway or high-mileage commuter use, which accelerates wear on suspension components, brake friction materials, clutch or dual-mass flywheel on the diesel variant, and drivetrain bearings. There is no apparent period where the odometer remained static for a prolonged absence of tests, indicating the car has been in regular service rather than left standing, which is generally positive for avoiding corrosion-related issues but raises the likelihood of mechanical fatigue in high-stress components. On a physical inspection, the advisory for a smooth brake pedal should be investigated carefully, as this often indicates worn pedal rubber that can become slippery when wet, but it may also mask a more serious master cylinder or servo issue if the pedal itself lacks firm resistance under foot. The damaged diesel particulate filter sensors warrant close attention given the recent exhaust emissions failure, which on a 2014 diesel Fiesta typically points to a clogged DPF, a failing differential pressure sensor, or an exhaust gas temperature sensor that is skewing readings. Ask for evidence of recent DPF cleaning or forced regeneration, and listen for any rattle or smell of unburned fuel from the exhaust on start-up. The nearside rear stop lamp failure recorded in 2024 should be checked to confirm it has been properly repaired and that the wiring has not deteriorated, as Ford tailgate harnesses on this era can suffer broken conductors where they flex into the tailgate. Given the high mileage, it is prudent to inspect the suspension comprehensively for wear, particularly the front track rod ends, as a dangerous defect was recorded on the nearside in February 2024 for excessive wear presenting a serious risk of detachment. Although replaced to achieve the subsequent pass, the fact that it failed to that severity suggests the surrounding bushes, wishbones, and anti-roll bar drop links are likely to be approaching replacement intervals now. Check for uneven tyre wear across the axle which would indicate camber or tracking issues, and feel for any knocking through the steering on uneven roads. Inspect the front coil springs for signs of corrosion or sagging, and verify the condition of the rear brake drums or discs for any lipping or binding calipers. Finally, although mileage is high rather than low, time-based servicing remains critical, so confirm the age of the cambelt and water pump if petrol, the dual-mass flywheel behaviour if manual diesel, and the condition of the brake fluid, coolant, and engine oil, all of which degrade with calendar years regardless of miles covered.
