2017 Vauxhall Insignia 1.6L Diesel · DN67 FKB

The most recent MOT test on 2026-03-18 resulted in a failure, with two major defects—near-side rear brake pads worn to the wear indicator and an offside rear coil spring fractured—alongside persistent advisories regarding front suspension arm bush wear and front oil dampness. This outcome contrasts with the previous MOT on 2024-09-11, which passed, indicating a deterioration in structural and braking integrity over the intervening period. The vehicle’s history also reveals recurring advisories on suspension components and uneven tyre wear, suggesting a pattern of wear progression rather than isolated incidents. While the 2023 and 2022 MOTs included advisories, the severity of the latest failure underscores the need for immediate attention to critical components, particularly the rear coil spring and brake system, which could compromise ride quality and safety if neglected. The 2017 Vauxhall Insignia’s mileage of 76,509 miles over nine years represents a moderate annual usage rate of approximately 8,501 miles, which is within the expected range for a vehicle of this age. However, the lack of a significant mileage gap between the 2021 and 2022 MOTs—suggesting relatively consistent driving—combined with the recent failures, implies that the vehicle has been subjected to wear beyond typical low-mileage expectations. Higher mileage in this context means accelerated consumption of suspension components, brake pads, and potentially drivetrain elements, all of which require closer monitoring. The presence of a fractured coil spring and worn brake pads at 76,509 miles highlights the importance of addressing these issues promptly, as rear suspension integrity directly affects handling stability and ride comfort, while brake performance is critical for stopping efficiency. For the prospective buyer, the most urgent actions should focus on the rear coil spring and brake system. The fractured offside rear coil spring is a major failure that must be replaced immediately to restore structural stability and prevent further damage to the sub-frame or suspension linkages. During a test drive, listen for excessive clunking or rattling from the rear during cornering or over bumps, which may indicate loose or failing suspension components. The near-side rear brake pads worn to the wear indicator necessitate immediate replacement to avoid reduced braking performance and potential overheating. Inspect the brake discs for warping or corrosion, and check for a binding or dragging caliper, which could cause uneven wear or reduced braking efficiency. Listen for a grinding noise when applying the brakes, which would confirm pad wear and the need for replacement. Beyond the immediate concerns, the vehicle’s history warrants thorough inspection of the front suspension, which has repeatedly been flagged for worn arm bushes and oil dampness issues. Visually inspect the front suspension arms for signs of excessive play or deformation, and check for oil leaks around the dampers, which could indicate failing seals or internal damage. The front tyres, while not failing the latest MOT, have shown significant wear—including edge wear and uneven patterns—suggesting misalignment or suspension misalignment. Measure the remaining tread depth and look for sidewall perishing, which can weaken tyre integrity over time. Given the vehicle’s age, also verify the condition of the 12V battery, as prolonged standing or high mileage can lead to reduced capacity or corrosion in the terminals. Finally, check the service history for fluid servicing, particularly brake fluid, differential fluid, and coolant, as these should be replaced according to manufacturer recommendations—typically every 2–3 years—to prevent degradation from prolonged exposure to air or heat.
