2013 Vauxhall Insignia 1.8L Petrol · DU63 ADZ

The Vauxhall Insigna’s most recent MOT tests, conducted just over a year ago on 27 August 2025, reveal a concerning pattern of repeated failures despite no recorded defects. Both the 2025 tests—conducted at identical mileages (82,774)—resulted in a pass followed immediately by a fail, suggesting either a technical error in the testing process or a vehicle that narrowly avoided critical failings. The previous cycle in 2022 also showed identical failures at 79,962 and 79,292 miles, with no defects logged, reinforcing the likelihood of a procedural oversight rather than genuine mechanical issues. The absence of advisories or defects across all tests implies the vehicle was not subjected to thorough inspection beyond the minimum legal requirements, leaving critical components unchecked. The recorded mileage of 82,774 miles over approximately 13 years (as of July 2026) averages around 6,367 miles annually, a rate consistent with typical usage for this age. However, the MOT history lacks intermediate tests, with the last valid checks spanning nearly two years between August 2022 and August 2025. This gap is unusual for a vehicle of this mileage and age, as it suggests either prolonged periods of non-use or a deliberate avoidance of regular inspections. The sudden accumulation of 3,500 miles between the 2022 and 2025 tests—from 79,292 to 82,774—without intermediate checks raises questions about whether maintenance was neglected during this period. Given the repeated failures and sparse inspection history, a prospective buyer should prioritise an independent inspection of high-wear components, particularly the suspension system, where bushes and coil springs often degrade silently. The repeated test failures, despite no defects being recorded, imply potential issues with brake binding or caliper wear, which could lead to uneven pad wear or disc damage. Structural integrity should also be scrutinised, as the lack of advisories in prior tests may mask corrosion in wheel arches, sills, or subframe areas—common in vehicles of this age. Finally, the exhaust system warrants close examination, as catalytic converter failures are frequently missed in basic MOT checks but can lead to catastrophic engine damage if ignored.
