2017 Ford Focus 1.5L Diesel · WH17 DFJ

The most recent DVSA examination on 6 January 2026 resulted in a clean pass with no advisories or defects recorded, and this continues a consistent pattern of uneventful tests stretching back to 2020. The only meaningful interruption was a failure on 30 June 2023 for a malfunctioning tyre pressure monitoring system, which was evidently rectified immediately as a subsequent pass was issued on the same date with no further recurrence. The single advisory from 2021 concerning an offside front inner tyre worn on its edge is a minor historical note and does not suggest any ongoing or systemic concern. Taken as a whole, the maintenance trend appears stable and well-managed, with no advisory accumulation, no recurring component failures, and no deterioration in test outcomes year on year. With approximately 65,336 miles recorded over nine years, the vehicle is running at an average of around 7,260 miles annually, which is broadly typical for a car of this age and suggests steady, regular use rather than extremes of high-mileage motorway work or prolonged periods of standing. This usage profile is generally favourable from a mechanical longevity standpoint, as consistent running helps to keep seals, brakes, the battery, and the exhaust system in healthier condition than a low-mileage garage queen. There are no significant mileage gaps in the MOT record that would indicate long periods of inactivity, which means calendar-based degradation of fluids and rubbers is less of a primary concern than it would otherwise be for a nine-year-old vehicle. Despite the clean MOT history, a prospective buyer should still carry out a thorough physical inspection given the vehicle's age. The 2021 advisory regarding inner-edge tyre wear warrants checking the offside front suspension geometry, including control arm bushes, wishbone bushes, and track rod ends, as inner-edge wear can indicate misalignment, worn suspension components, or even a slightly bent component following kerb impact. On a test drive, listen for clonks or knocks over bumps, pay attention to steering vagueness or pulling to one side, and feel for any vibration through the steering wheel which could indicate warped brake discs or imbalanced wheels. Inspect all four tyres not just for tread depth but for age-related sidewall cracking and perishing, as tyres older than five or seven years should be replaced regardless of remaining tread. Beyond the tyres, attention should be given to the braking system, exhaust, and ancillaries appropriate to a 2017 vehicle approaching a decade of service. With this mileage, the front brake discs and pads may be approaching their second or third replacement, so check for lipping on the disc edges, pulsing under braking, and ensure the caliper slides move freely without binding. Examine the exhaust system for corrosion, paying particular attention to mounting rubbers and the rear silencer box, and listen for any blowing or rattling on start-up which could indicate a failing flex joint or corroded pipe. Verify the 12V battery holds charge under load, as original units of this age frequently deteriorate; confirm that the service book shows regular oil and filter replacements at appropriate intervals, and consider renewing the brake fluid, coolant, and transmission fluid if there is no documentary evidence of recent changes, as these degrade on a calendar basis rather than purely by mileage. Finally, check the bodywork and undercarriage for any localised corrosion, particularly around the wheel arches and under the bonnet, as Focus models of this generation can be susceptible to surface rust in these areas.
