2015 Vauxhall Insignia 2.0L Diesel · FP15 POU

The most recent DVSA MOT test on the Vauxhall Insignia, conducted on 2026-08-06, resulted in a passing grade, though it revealed several persistent advisories that warrant careful consideration. The overall maintenance trend over the past decade is inconsistent, with a notable failure in 2021 due to a major offside rear coil spring fracture, followed by recurring issues with tyre wear and structural components. While the vehicle has passed subsequent tests, the presence of advisories—particularly regarding tyre wear close to legal limits, minor cuts, and coil spring corrosion—suggests that while the car remains roadworthy, its condition is not entirely optimal. The combination of these advisories indicates a pattern of wear that may require proactive attention to prevent escalation into more serious faults. The recorded mileage of 60,958 miles for a vehicle aged approximately 11 years represents a relatively low annual usage rate of around 5,542 miles per year, which is unusual for a car of this age and model. Lower mileage can stem from infrequent use, long periods of standing, or a preference for alternative transportation. However, this usage profile may mask underlying issues that have developed from prolonged exposure to environmental factors, such as corrosion from stationary conditions or fluid degradation without regular servicing. The most critical implications of low mileage are the potential for tyre sidewall perishing due to age-related cracking, standing corrosion in the suspension and exhaust systems, and the risk of brake system degradation from prolonged inactivity, which can lead to binding or reduced effectiveness. To conduct a thorough physical inspection, the prospective buyer should prioritise checking the tyre condition for signs of sidewall cracking or perishing, which can compromise structural integrity and safety, especially given the recent advisories on tyre wear. Inspect the front and rear suspension for any signs of corrosion on the coil springs, particularly the offside rear spring noted in the 2026 MOT, and listen for unusual clunking or rattling noises when driving over bumps, which may indicate worn suspension bushes or damaged struts. The brake system should be examined for signs of binding calipers, particularly on the front brakes, where the 2023 MOT recorded minor binding without excessive wear. Additionally, verify the condition of the exhaust system for corrosion or leaks, as the 2021 failure highlighted the fragility of the coil spring, which could recur if not addressed. For fluid servicing, the buyer should consider a comprehensive check of all fluids, including the brake fluid, which should be replaced every 2–3 years due to its hygroscopic nature and potential for standing corrosion. The coolant system should also be inspected for signs of degradation, as prolonged exposure to heat and age can lead to sludge formation or leaks. The 12-volt battery should be tested for voltage output and overall health, especially given the low mileage, as standing vehicles are prone to battery drain from parasitic loads or internal corrosion. Finally, a thorough inspection of the exhaust emissions system is advisable, as the Vauxhall Insignia’s catalytic converter and oxygen sensors may degrade over time, particularly if the vehicle has been stationary for extended periods. If any of these checks reveal issues, addressing them promptly will help maintain the vehicle’s roadworthiness and longevity.
