2016 Vauxhall Insignia 1.6L Diesel · SC65 FBO

The most recent MOT test on 2026-01-30 resulted in a clean pass, marking a return to compliance after two consecutive failures in early 2026, both of which were major defects related to the rear coil springs of the Vauxhall Insignia. The failure history indicates a critical wear issue in the suspension system, with both near-side and offside rear coil springs fractured or broken during the previous test. While the vehicle has now passed, the prior failures suggest a pattern of progressive suspension degradation, which could imply underlying structural fatigue or poor maintenance practices affecting the springs and potentially their mounting points or associated components. The advisory and minor defects from previous years—such as worn tyres, deteriorated CV joint boots, and non-functional licence plate lamps—highlight recurring areas of wear and potential neglect, though these have not escalated to major failures. The recorded mileage of 72,081 miles for a vehicle aged approximately ten years represents a moderate annual usage rate of around 7,208 miles per annum, which is within the expected range for a car of this age and class. Such mileage does not necessarily indicate excessive wear if the vehicle has been maintained regularly, but it does suggest consistent operational use rather than prolonged periods of inactivity. However, the combination of relatively high mileage and the presence of coil spring failures raises concerns about the potential for accelerated wear in other suspension components, such as bushes, bushings, and potentially the subframe or wishbones, which may have already experienced stress cycles contributing to the spring failures. The lack of a service history or detailed maintenance records further complicates the assessment, as wear patterns could be influenced by factors like driving style, road conditions, and whether the vehicle was frequently driven or stood idle for extended periods. Given the history of coil spring failures and the associated advisories and minor defects, the prospective buyer should prioritise a thorough inspection of the suspension system during the purchase process. Focus on the rear suspension geometry, checking for excessive play or binding in the coil springs, which could indicate further fatigue or mounting issues. Listen for unusual clunking or rattling noises during the test drive, particularly when driving over bumps or at speed, as these may reveal worn suspension components or misaligned wheels. Inspect the rear tyres for uneven wear patterns, which could signal suspension misalignment or camber issues stemming from the coil spring failures. Additionally, verify the condition of the CV joint boots and drive shafts, as their deterioration from previous years’ advisories may have progressed, potentially leading to transmission or drivetrain problems if left unaddressed. Immediate attention to the suspension should include replacing the failed coil springs and assessing the mounting hardware for signs of corrosion or damage, as well as checking the alignment and balance of the wheels to ensure safe and efficient operation. For the broader vehicle assessment, the buyer should also conduct a visual and functional inspection of the vehicle’s standing condition, particularly focusing on areas prone to corrosion from prolonged idleness. Check the undercarriage for signs of rust, especially around the rear suspension mounts, exhaust system, and wheel arches, as these areas are commonly affected by moisture exposure. Inspect the tyres for sidewall perishing or cracking, which can occur even at moderate mileage due to age-related degradation of the rubber compound. Test the braking system by applying the brakes firmly and listening for any signs of binding, shuddering, or excessive heat, which could indicate worn brake discs, pads, or warped rotors. Verify the condition of the 12-volt battery and associated electrical systems, as older vehicles may experience reduced performance or failure due to age-related battery degradation, particularly if the vehicle has been stored for extended periods. Finally, ensure that the vehicle’s service history is up to date, with particular attention to the timing of fluid changes—such as the brake fluid, coolant, and transmission fluid—since these fluids degrade over time regardless of mileage, and their replacement is critical for maintaining roadworthiness and component longevity.
