2017 Ford Focus 1.5L Diesel · WN17 VLZ

The most recent MOT, conducted on 8 July 2022 at 91,926 miles, passed with zero defects. However, this clean result sits at the end of a concentrated cluster of failures earlier that same year, making the maintenance trend difficult to read as genuinely stable. Between January and April 2022, the car failed three times in quick succession, all within a narrow mileage band of roughly 91,855 to 91,895 miles. The tester repeatedly flagged a diesel particulate filter issue producing visible smoke, exhaust emissions exceeding the manufacturer's specified limit, and a parking brake system with insufficient reserve travel and poor efficiency. A January failure also recorded a damaged nearside rear tyre sidewall with a nail puncture. The fact that these faults disappeared by the July retest suggests the previous owner carried out targeted repairs rather than allowing a chronic problem to persist. Still, the record ends there, and no further MOT entries exist to confirm whether the underlying causes, particularly the DPF and emissions faults, have remained resolved over the last four years. The mileage pattern raises a significant question for any prospective buyer. Between the March 2021 pass at 76,150 miles and the January 2022 failure at 91,855 miles, the car covered roughly 15,700 miles in ten months, a sharp jump averaging over 1,500 miles per month. Yet from January 2022 through July 2022, the recorded mileage barely moved, climbing just 71 miles across six months. After July 2022, the mileage remains frozen at 91,926 with no subsequent MOT recorded. This plateau is unusual. It could indicate the vehicle has been sitting unused for an extended period, or it could point to a gap in testing that obscures genuine use. Either scenario demands closer scrutiny. A buyer should focus the physical inspection on the components that failed repeatedly in early 2022. The exhaust and DPF system warrants a thorough check: look for soot staining around manifold and pipe joints, listen for blow-by at the turbocharger connections, and verify that the DPF warning light behaves correctly on a cold start. The parking brake system needs equal attention. Excessive lever travel and low efficiency suggest either stretched cables, maladjusted rear calipers, or worn brake shoes if the car uses a drum-in-disc setup. Inspect the rear brake assemblies for seized sliders or binding handbraque mechanisms, as these faults can recur if only superficially addressed. The nearside rear tyre damage and puncture earlier in 2022 also point to a need for a close look at all four tyres and inner wheel arches for embedded debris or sidewall deterioration, particularly if the car has been stationary for long periods. Beyond the flagged items, the extended gap since the last MOT means corrosion and rubber component ageing should not be overlooked. Check the underside for structural rust on subframes, suspension mounting points, and brake lines, as a vehicle sitting unused can develop surface corrosion that accelerates once returned to regular use. Inspect all suspension bushes, coil springs, and shock absorbers for perishing or weeping, and verify that no new advisories have accumulated during the untested period. A compression test and an exhaust gas analysis would provide the clearest picture of engine health given the earlier emissions failures.
