2017 Ford Focus 1.5L Diesel · R70 JBA

The most recent MOT, conducted on 24 February 2026, recorded a pass with no defects, but it follows a failure on the preceding day for excessive exhaust emissions. Across the seven‑year record the vehicle has alternated between clean passes and a series of advisories and failures – tyre tread depth in 2024, tyre damage and uneven wear in 2025, thin front brake pads in 2022 and the current emissions breach. This pattern indicates a maintenance trajectory that is becoming less stable, with recurring tyre concerns and a new emissions issue suggesting that the car may be entering a period of increasing wear and component degradation. At 41,886 miles the 2017 Focus averages roughly 4,650 miles per annum, well below the typical UK usage of 7‑10 thousand miles a year. Such low mileage often reflects periods of limited use or prolonged storage, which can be as detrimental as high mileage in terms of ageing of rubber, metal corrosion and fluid breakdown. The modest annual distance does not offset the risk of components ageing in situ; for example, tyre sidewalls may have perished despite low wear, and brake discs can develop rust when the vehicle sits for extended periods. Prospective buyers should give particular attention to the tyre and exhaust condition. Inspect all four tyres for sidewall cracking, dry rot and tread depth well above the legal 1.6 mm limit, remembering that the rear tyres were previously deemed dangerous and the front tyres showed early cracking. Look for uneven wear patterns that could signal mis‑alignment, worn suspension bushes or incorrect tyre pressures. During a test drive listen for any whine or clatter from the exhaust system and note any black smoke or unusual engine note, as the recent emissions failure may point to a failing catalytic converter, injector fouling or an air‑fuel mixture problem that will require diagnostic scanning and likely component replacement. In addition, verify the health of the braking system – the 2022 advisory about thin front pads suggests that the pads may be approaching the end of their service life and the discs could be corroded from inactivity. Check that the calipers move freely and that there is no pulsation or shudder when applying the brakes. Examine the battery terminals for corrosion and have the charge tested, as a vehicle with long idle periods often suffers reduced battery capacity. Finally, inspect the under‑carriage for rust, especially around the wheel arches and suspension mounting points, and confirm that the engine oil, coolant and gearbox fluids have been changed in line with calendar intervals rather than mileage alone. A thorough visual inspection combined with a sensible road test will reveal whether the car’s low mileage truly reflects gentle use or concealed ageing.
