2004 Volkswagen Polo 1.4L Petrol · LS04 KZM

The most recent MOT on 2025-08-05 recorded a pass at 75,929 miles, but a failure just 5 days earlier on 2025-07-31 highlighted two critical issues: an inoperative engine MIL (indicating a potential fault) and a split windscreen washer pipe. These suggest intermittent or unresolved problems with the vehicle’s diagnostic systems and fluid integrity. The failure was addressed before the subsequent pass, but the proximity of the two events raises concerns about the reliability of the vehicle’s systems. Recurring mechanical patterns include repeated failures of anti-roll bar ball joint dust covers, first noted in 2023-08-08 (damaged) and 2023-08-07 (severely deteriorated). These issues resurfaced in 2024-08-05 (nearside track rod end dust cover) and were likely unresolved by 2025. Deteriorated dust covers allow dirt ingress, accelerating wear on suspension components. This indicates a persistent lack of maintenance or a design vulnerability in the vehicle’s suspension system. The trend shows worsening conditions. While earlier MOTs in 2023 and 2024 recorded minor issues, the 2025 failure introduced a critical engine MIL fault, which could signal underlying engine or emissions problems. The vehicle’s low mileage (3,451 miles per year) suggests either light use or prolonged periods of inactivity, which can cause rubber and seal components to degrade.
