2016 Vauxhall Insignia SRI NAV Cdti Auto 1.6L Heavy oil · LP65 CGO

The most recent DVSA examination on 23 November 2025 resulted in a PASS with no defects or advisories recorded, and this clean outcome is consistent with the preceding four tests conducted between 2020 and 2024, all of which passed without any advisories. Such a defect-free run over five consecutive annual examinations indicates a stable and well-maintained mechanical condition, suggesting that the vehicle has been subject to a consistent standard of preventative upkeep. The absence of recurring advisories related to suspension components, brake wear, or corrosion is particularly encouraging for a car of this age, as these are the areas most commonly flagged on higher-mileage vehicles. Overall, the MOT trajectory demonstrates a steady, well-cared-for example rather than one showing progressive deterioration. The recorded mileage of 108,020 miles over a ten-year registration period equates to an average annual usage of approximately 10,800 miles, which is broadly typical for a vehicle of this age and class. There is no evidence in the DVSA record of excessive mileage accumulation or extended standing periods between tests, with annual readings following a logical incremental progression. While the mileage is moderate rather than low, it is not unusually high, meaning that major drivetrain components such as the diesel engine and automatic transmission have experienced regular working cycles rather than being subjected to the added stresses of short journeys or prolonged inactivity. For a diesel-powered automatic Insignia of this age and mileage, this usage profile is generally favourable from a component longevity perspective. Although the MOT history is commendably clean, a prospective buyer should still conduct a thorough physical inspection, as the DVSA test does not cover every age-related wear item. The tyres warrant particular attention, specifically checking the sidewalls for perishing and cracking caused by environmental exposure over the past decade, even if the tread depth remains legal. The wheels and brake assemblies should be examined for signs of corrosion around the disc edges or seized caliper slider pins, which is common on vehicles subjected to mixed driving conditions. It is also advisable to inspect the exhaust system for surface corrosion at the mounting points and pipe joints, as ten-year-old diesel exhausts frequently exhibit early-stage rusting. Under the bonnet, the coolant, brake fluid, and automatic transmission fluid should be checked for age-related degradation, with a service history review confirming whether these have been changed in accordance with manufacturer time-based intervals rather than purely mileage-based schedules. On a test drive, the buyer should listen for any clonking or knocking from the front suspension, particularly over speed humps and uneven surfaces, which would indicate worn lower wishbone bushes or drop links typical of Insignias approaching or exceeding the 100,000-mile mark. The automatic gearbox should be tested for smooth, prompt changes across all ratios, with particular attention to any hesitation, flare, or harsh engagement that could suggest internal wear or low/contaminated transmission fluid. The diesel engine should be assessed from cold start for excessive smoke, rough idle, or excessive timing-chain rattle, and once warmed up should run smoothly without misfires or unusual vibrations. Finally, verifying the 12-volt battery health is worthwhile, as units over six years old often struggle to maintain charge, especially during colder months, and ensuring the service book contains evidence of regular cambelt and water pump replacement in line with Vauxhall's diesel intervals will provide further confidence in the vehicle's long-term mechanical integrity.
