2017 Vauxhall Insignia 1.6L Diesel · KY17 LOJ

The vehicle is currently roadworthy, but the maintenance trend shows a concerning shift toward reactive repairs. While the car passed its most recent test in November 2025 at 166,952 miles, this followed a significant failure just one day prior. That failure revealed critical engine issues, specifically excessive exhaust emissions and dense blue smoke, which typically indicate internal mechanical distress such as injector wear or turbocharger failure. The fact that the vehicle passed immediately after these failures suggests the owner only addresses faults when legally compelled, rather than performing proactive preventative maintenance. At 166,952 miles over nine years, this Insignia has covered a high average of approximately 18,500 miles annually. This intensive usage profile places substantial strain on the drivetrain and suspension components. The data shows consistent high mileage accumulation, with roughly 6,500 miles driven between February 2024 and November 2024, and another 6,600 miles in the following months. Such high mileage suggests the vehicle was used for frequent motorway commuting, which explains the accelerated wear on consumables like the nearside front tyre noted in the recent test history. A buyer must conduct a thorough physical inspection of the engine and suspension systems. The recurring blue smoke recorded in November 2025 is a major red flag for long-term engine health and may require a specialist to diagnose fully. Furthermore, the serious fluid leak on the nearside rear shock absorber indicates that the suspension is reaching the end of its life; you should check the remaining shocks for similar weeping. The uneven edge wear on the nearside front tyre also suggests an alignment issue or worn suspension bushes that require attention to prevent further premature tyre degradation.
