2015 Vauxhall Insignia 2.0L Diesel · SM15 VPU

This Vauxhall Insignia has maintained a consistent roadworthiness record over the past three MOT cycles, with the most recent test on 10 April 2026 confirming no defects and a clean pass. The absence of advisories or recurring failures across the last three tests suggests the vehicle has been kept in stable mechanical condition, though the 2023 test date—just eight months prior to the failure—appears anomalous. The failure itself was recorded without defects, which may indicate a procedural error rather than a mechanical issue, but the lack of any subsequent advisories or defects in the intervening tests implies no unresolved underlying problems. The recorded mileage of 87,848 miles over approximately 11 years equates to around 7,986 miles per year, which aligns with typical usage patterns for a vehicle of this age. There are no obvious gaps or spikes in mileage between tests, though the irregular spacing of the 2023 tests (a failure followed immediately by a pass) could warrant scrutiny of the vehicle’s service history. The most recent test was conducted just under five months ago, which is within the standard MOT validity period, but the lack of any advisories does not preclude the need for a thorough pre-purchase inspection. Given the clean MOT history, the primary focus of an in-person inspection should be on high-wear components that are not directly tested under MOT but are critical to long-term reliability. The suspension—particularly the rear bushes and coil springs—should be examined for excessive play or corrosion, as these are common failure points in vehicles of this age and mileage. Brake systems, including caliper binding, uneven wear on discs, and the condition of the rear brake shoes, should be checked, as the absence of MOT advisories does not guarantee they have been recently serviced. Additionally, the structural integrity of the chassis and wheel arches should be assessed for signs of corrosion, especially around the rear wheel housings and sills, where rust can compromise safety. The engine bay and drivetrain components, such as the timing belt (if applicable) and power steering fluid condition, should also be inspected, as these are not covered by MOT but can fail catastrophically if neglected. The lack of advisories in recent tests does not rule out deferred maintenance, so attention to detail—particularly in areas not routinely checked—will be essential. The vehicle’s recent MOT history is reassuring, but the irregular 2023 test dates suggest a history that may not have been meticulously documented.
