2012 Vauxhall Insignia 2.0L Diesel · DS12 WHJ

The Vauxhall Insignia’s most recent MOT tests, conducted just six months ago on 2025-11-20, reveal a concerning pattern of repeated failures despite identical mileage readings. Both tests at 106,806 miles were recorded as both passed and failed on the same date, which suggests either a clerical error or a deliberate attempt to bypass proper inspection—an anomaly that undermines confidence in the vehicle’s true roadworthiness. The lack of any recorded defects in the 2023 and 2024 tests at lower mileages (100,331 and 103,678 miles) implies that the vehicle may have passed without scrutiny until the most recent cycle, raising questions about whether critical components were overlooked or deliberately ignored. The mileage progression of approximately 3,128 miles per year (from 100,331 to 106,806 miles between 2023 and 2026) aligns with typical usage for a vehicle of this age, though the abrupt doubling of tests at the same mileage in 2025 is unusual. There are no gaps suggesting prolonged neglect, but the repeated failures at the same mileage—despite no defects being logged—suggest either a systematic issue with the testing process or a vehicle that may have been driven with deferred maintenance. The absence of advisories in prior tests means no prior warnings about suspension wear, brake fade, or structural corrosion were documented, which could indicate either diligent upkeep or a failure to address minor issues early. Given the irregularities in the 2025 MOT results, a buyer should prioritise an independent inspection of the suspension components, particularly the rear bushings and coil springs, which are common failure points on this model at this mileage. The repeated test failures at identical mileages warrant scrutiny of the braking system, including rear caliper binding, warped discs, or master cylinder leaks, as these are frequently flagged in MOT failures. Additionally, the absence of corrosion advisories in prior tests does not guarantee structural integrity—rust around wheel arches, sills, and the subframe should be thoroughly checked, as this is a critical failure risk for vehicles of this age. The engine bay and exhaust system should also be examined for leaks or excessive wear, particularly if the vehicle has been driven with deferred maintenance.
