2015 Vauxhall Insignia 2.0L Diesel · VX02 ALL

The vehicle remains roadworthy, but the maintenance trend shows signs of decline regarding structural and consumable upkeep. While the most recent test in January 2026 at 154,637 miles resulted in a pass, it introduced several advisories that were absent in previous years. The appearance of corrosion on both the front and rear sub-frames indicates that the vehicle is entering a phase where structural degradation will require close monitoring to prevent a failure in future tests. At 154,637 miles, this Insignia has covered a significant distance for its age, averaging approximately 14,000 miles per year. The data shows consistent usage patterns, with roughly 6,000 to 7,500 miles driven between each annual inspection. This high mileage places considerable stress on the drivetrain and suspension components. The clean records between 2023 and 2025 suggest a period of adequate mechanical health, but the recent defects indicate that the high mileage is beginning to outpace standard service intervals. A buyer must prioritise a physical inspection of the sub-frames to determine the depth of the corrosion noted in the 2026 test. While the tester marked it as not seriously weakened, surface rust on these components can accelerate rapidly in salted road conditions. Additionally, the recurring issue with uneven tyre wear on the rear axle, noted in 2022 and again in 2026, suggests a persistent wheel alignment problem or worn suspension bushes that have not been addressed. The inoperative registration plate lamp is a minor fix but should be rectified to ensure full legal compliance.
