2015 Vauxhall Insignia 2.0L Diesel · AW15 FXG

The Vauxhall Insignia’s most recent MOT test on 2025-12-16 passed without defects, marking the first successful outcome following a failure on 2025-12-08—an unusual but isolated anomaly. The preceding tests from 2024-12-13, 2023-12-16, 2022-12-17, and 2021-12-17 all passed cleanly, suggesting a stable maintenance pattern with no recurring advisories or faults. The failure in December 2025, however, warrants scrutiny, as it lacks recorded defects, which may indicate an administrative or procedural oversight rather than a mechanical issue. Without further context, this single failure does not imply a worsening trend, but it does necessitate verification of its cause. The vehicle’s mileage of 130,441 miles over approximately 11 years equates to roughly 11,858 miles annually, a rate consistent with typical usage for its age. There are no evident gaps or spikes in the MOT schedule, as tests have been conducted annually without exception. This regularity suggests the vehicle has been driven steadily rather than left unused for prolonged periods, which could otherwise accelerate wear on suspension bushes, coil springs, and drivetrain components. Given the lack of recorded defects in recent MOTs, the primary focus for an in-person inspection should centre on components prone to wear at this mileage. The suspension—particularly the rear bushes and coil springs—should be examined for excessive play or corrosion, as these often fail silently before becoming MOT-critical. Brake systems, including rear binding calipers and warped discs, are another critical area; while not flagged in tests, repeated braking loads at this mileage can lead to uneven wear. Structural integrity, especially around wheel arches and sills, must be checked for corrosion, as Vauxhall Insignias from this era are susceptible to rust progression over time. Finally, verify the exhaust system for leaks or damaged mounts, as emissions-related failures are not uncommon in older models despite passing tests.
