2013 Ford Focus 1.6L Diesel · FP13 WCD

A pattern of rear axle deterioration and recurring minor electrical defects defines the mechanical history of this 2013 Ford Focus, with the most recent test on 12 November 2025 recording a pass alongside two advisories directly related to the rear wheels and underbody. The vehicle returned a fail on 30 October 2025, driven by inoperative stop lamps and a nearside rear tyre measuring just 1.5mm of tread, which was classified as dangerous with cords visible on the inner edge. Prior tests in 2024 and 2022 also produced fails, though the 2024 failure carried no major or dangerous defects, only a collection of advisories. The advisories, when read as a sequence, point to a chronic pattern: rear coil spring corrosion flagged in 2022, a light oil misting on the offside rear shock absorber in 2024, and general underbody corrosion noted at both 2025 tests, suggesting progressive degradation of the rear suspension and structural metalwork that warrants close physical inspection. Recorded mileage stands at 101,339 miles over approximately 13 years, which equates to an annual accumulation of roughly 7,800 miles, consistent with typical commuter use for a vehicle of this age. The mileage progression between tests is steady rather than erratic, with no unusual spikes or extended gaps in MOT coverage that would imply long periods of standing or sudden changes in usage. This level of consistent running generally keeps the drivetrain and seals active, though it does mean that common Focus wear items such as suspension bushes, anti-roll bar links, and clutch components will have accrued substantial in-service fatigue. The absence of mileage-related advisories on braking components or exhaust emissions suggests the mechanical consumables are being replaced in line with wear, but the rear-end corrosion narrative is the dominant concern for a buyer. A prospective buyer should focus their physical inspection on the rear suspension and underbody, given the documented coil spring corrosion, shock absorber oil misting, and general underbody corrosion. On a test drive, listen for clonks or knocking from the rear over uneven surfaces, which would indicate weakened coil springs or worn trailing arm bushes, and pay particular attention to any uneven ride height at the rear corners. The underbody should be examined on a ramp for scale loss on the rear axle, spring seats, and subframe mounting points, as the advisory language used in 2022 and 2025 suggests surface corrosion that could progress to structural concern if left unchecked. The offside rear shock absorber, noted as misting in 2024, should be inspected for fresh oil residue and tested by pushing down firmly on the rear corner to confirm it dampens without bouncing. Further checks should centre on the electrical and lighting systems, which have produced multiple advisories and majors across the recorded history. Stop lamps, position lamps, headlamp dipped beam, and the horn have all failed at various points, suggesting either aged wiring, a failing multifunction switch, or bulb holder corrosion. A walk-around prior to purchase should confirm all exterior lamps function consistently and that the horn operates on first press. Tyre wear is another critical area, as the nearside rear tyre was found dangerously worn in late 2025 and the offside rear was simultaneously at the legal limit, indicating either an unresolved geometry issue at the rear or simply neglected replacements. After any new tyres are fitted, the wheel alignment should be verified, and the inner edges of all four tyres should be inspected periodically for uneven wear patterns consistent with the camber or tracking problems that this record implies.
