2015 Vauxhall Insignia 2.0L Diesel · MD15 MYA

This Vauxhall Insignia’s most recent MOT tests—conducted just ten months ago on 2 July 2025—show an unusual but technically stable pattern: two consecutive tests at the same mileage (103,258), one passing and one failing without recorded defects. While the lack of specific fault codes makes it impossible to confirm the failure reason, the absence of defects in the passing test suggests either a minor administrative oversight or a test centre error. The previous clean history from September 2023 and August 2022 (both at high mileages) reinforces that the vehicle has not experienced recurring mechanical issues, though the double-test anomaly warrants scrutiny of service records for potential undocumented work. The recorded mileage progression reveals a steady but slightly above-average annual average of 9,387 miles, consistent with typical usage for its age. There are no obvious gaps or spikes in mileage between tests, though the identical mileage at two consecutive 2025 tests is unusual and may indicate the odometer was not reset or that the vehicle was not driven between tests. The 2022–2023 period shows a slower accumulation (around 6,465 miles per year), which could imply lighter use or seasonal variations, but the overall trend does not suggest aggressive driving or neglect. Buyers should verify whether the odometer readings align with the vehicle’s actual usage, particularly around the 2025 test dates. Given the lack of specific MOT defects, the most critical areas for an in-person inspection would be the suspension components—front and rear coil springs, bushes, and dampers—given their typical wear patterns at this mileage. The double MOT tests in 2025, despite passing, raise questions about brake performance, particularly if binding calipers or uneven wear were present but not recorded. Structural integrity should also be checked for corrosion in wheel arches, sills, and subframes, as rust can compromise safety without always being flagged in an MOT. Finally, the exhaust system and emissions should be inspected for leaks or excessive smoke, as these are common failure points that may not always appear in a passing test. The absence of advisories in prior tests suggests no major deferred repairs, but a thorough mechanical check is essential to confirm the vehicle’s true condition.
