2015 Vauxhall Insignia 2.0L Diesel · Y16 ULE

The vehicle is currently roadworthy but the maintenance trend shows a shift toward developing mechanical wear and minor structural degradation. The most recent test in October 2025 at 101,694 miles identified multiple advisories including a minor exhaust leak, corroded fuel filler pipes, and binding front brake calipers. While the car passed without failures, the appearance of these distinct issues after a clean record the previous year suggests the vehicle is entering a phase where aging components require proactive attention to prevent future MOT failures. At 101,694 miles over eleven years, the Insignia averages approximately 9,245 miles per year, which aligns with typical national averages for its age. The data shows a consistent usage pattern, with roughly 20,000 miles driven between August 2023 and October 2025, and another 21,000 miles prior. This regularity suggests the vehicle has not sat stationary for long periods, which is generally positive for seals and mechanical, despite the mileage-related wear seen in the suspension components. A buyer must prioritize a thorough inspection of the suspension and braking system. The record from 2022 highlighted significant corrosion on rear camber arms and fractured coil springs, while the 2023 test noted worn rear upper suspension arm bushes, indicating the rear subframe area is a point of recurring vulnerability. Additionally, the binding of both front service brakes noted in the 2025 test indicates likely sticking calipers or seized pistons which will lead to uneven pad wear and reduced stopping efficiency. The minor exhaust leak at the middle silencer should be monitored or addressed, as even small leaks can lead to failed emissions tests if they expand. The corroded offside rear fuel pipe also requires close visual inspection to ensure there is no risk of leakage. Given the history of corrosion on the suspension arms, a physical check of the chassis integrity and rear mounting points is necessary to confirm that structural rust has not progressed beyond the surface level noted in previous tests.
