2017 Ford Fiesta 1.0L Petrol · WF67 FPP

A near-term MOT record of two pass results, the most recent on 17 September 2025, frames a vehicle that is broadly roadworthy on test, but the underlying history is not entirely uneventful. Across eight recorded tests since 2020, the Fiesta has accumulated two failures and two advisories, with the most recent pass in 2025 and the previous one in 2024 both recorded with no defects. The earlier 2024 entry on 11 September was a straight fail on the offside front drive shaft CV boot, which was retested and passed the following day, indicating the defect was addressed promptly rather than being an ongoing structural concern. A separate failure in September 2023 for an out-of-specification exhaust Lambda reading after the second fast idle is a more ambiguous item, as it can be triggered by a deteriorated oxygen sensor, an exhaust leak ahead of the lambda, or an engine management issue, and the car passed the same day on the retest, suggesting the cause was resolved at that time. Two advisories were raised in September 2022 for slight damage and perishing on both rear tyres, an age-related rubber degradation issue common to low-mileage vehicles that have stood for long periods. Against an age of roughly nine years, the recorded odometer figure of 33,409 miles equates to an average annual accumulation of approximately 3,712 miles, which is materially below typical usage for a Fiesta of this vintage. There are no conspicuous gaps in the testing record, with annual tests consistently presented from 2020 through 2025, and the mileage progression between tests appears steady and proportionate rather than showing any anomalous jumps or clocked readings. Mechanically, this level of use tends to place the vehicle in a middle ground where wear items such as brake pads, discs, and tyres may have aged through material degradation rather than being worn through, while components like the timing belt, coolant, and clutch may still have substantial service life remaining. The principal risk associated with low annual mileage is the rubber and sealing deterioration flagged by the 2022 tyre advisories and the 2024 CV boot failure, both of which are consistent with underuse rather than overstress. A prospective buyer should pay particular attention to the offside front drive shaft area, as the 2024 failure for a split CV boot suggests the joint may have been exposed to contamination. Even with a replacement boot fitted at the retest, the CV joint itself can suffer latent damage that manifests as a clicking or knocking noise on full lock at low speed, or as a vibration under load. The Lambda sensor failure of 2023 also warrants follow-up, as a recurring oxygen sensor fault or an unresolved exhaust leak ahead of the catalyst can produce driveability symptoms including uneven idle, hesitation on light throttle, and elevated fuel consumption, alongside a possible reappearance of an emissions-related test failure. A visual inspection under the bonnet for any residual staining around the exhaust manifold joint, downstream lambda wiring, and oxygen sensor connector would be worthwhile. On a test drive, the items worth exercising deliberately include brisk low-speed turns in either direction to provoke any CV joint noise, and a steady motorway cruise to detect any vibration or hesitation that could point to exhaust or lambda issues. Given the age, a thorough check of the underbody for corrosion is sensible, particularly around the suspension subframes, rear axle beam, brake pipes, and jacking points, as corrosion advisories tend to develop on Fiestas of this generation once they pass the eight-year mark. The brakes should be assessed for smooth operation without pulling, and the tyres, particularly the rear pair, examined for sidewall cracking in line with the 2022 advisories, replacing both rear tyres as a precaution if perishing is visible. Finally, a mechanical inspection including engine oil condition, coolant strength, and the state of the auxiliary drive belt would help confirm whether the low recorded mileage corresponds to genuinely preserved mechanical condition or to long static periods that have allowed rubber and sealing components to deteriorate ahead of the mechanically worn items.
