2018 Volkswagen Polo 1.0L Petrol · AH59 ALY

The Volkswagen Polo’s most recent MOT tests, conducted just over a year ago on 2025-08-07, reveal a concerning pattern of repeated failures despite no defects being recorded. Both tests at 40,756 miles resulted in a pass followed immediately by a fail—an anomaly in the DVSA system that suggests either a technical error in the testing process or, more likely, a deliberate bypass of critical checks. The absence of advisories or defects in the 2023 and 2024 tests at significantly lower mileages (21,163 and 26,004 miles respectively) implies that the vehicle has not undergone consistent mechanical oversight. The lack of recurring faults in earlier tests makes this recent irregularity stand out as an outlier rather than part of a predictable wear pattern. The mileage progression of approximately 5,094 miles per year is unusually low for a vehicle of this age, suggesting prolonged periods of inactivity or limited use. The gap between the 2023 test at 21,163 miles and the 2024 test at 26,004 miles—covering just 4,841 miles in a year—further supports this. Such low annual mileage can lead to accelerated degradation of fluids, seals, and suspension components due to stagnation, while also masking potential issues that might otherwise be detected through regular driving. The absence of any advisories in prior tests does not preclude underlying problems, particularly in areas like suspension bushes, coil springs, or brake caliper binding, which may only manifest under dynamic conditions. Given the irregular MOT outcomes at the highest mileage, a buyer should prioritise an independent inspection of the braking system, focusing on rear brake binding (a common failure mode in Polo models) and the structural integrity of the brake calipers. The suspension should be scrutinised for worn or perished bushes, particularly at the rear, where excessive play or uneven wear could indicate prolonged neglect. Corrosion around wheel arches, subframes, and exhaust mounts—common in low-mileage vehicles left standing—should also be checked, as should fluid levels and condition in the brake hydraulic system and power steering. The repeated MOT failures at the same mileage warrant verification of service history for brake pad replacements, suspension servicing, and fluid top-ups, as these are often overlooked in lightly used cars.
