2015 Vauxhall Insignia 2.0L Diesel · MM64 OCB

The most recent DVSA test, dated 3 November 2025, recorded a failure on account of a fractured off‑side rear coil spring, a major safety defect, together with advisories concerning a loose central front under‑tray and thin rear brake pads. Although the vehicle has previously passed its MOT, the recurrence of serious suspension and brake‑related items indicates a maintenance trajectory that is now deteriorating rather than stabilising, with the latest failure pointing to a component that should have been addressed earlier. At 116,147 miles the car averages roughly 10,500 miles per annum, which sits comfortably within the normal usage envelope for a 2015 model. The mileage record shows no evidence of prolonged periods of inactivity that would raise concerns about tyre perishing or battery sulphation, nor does it suggest any abrupt mileage spikes that would accelerate wear on drivetrain or suspension elements. Nevertheless, a vehicle with just over a hundred thousand miles will have experienced considerable wear on consumables such as brake discs, pads, bushings and shock components, and the recorded mileage underlines the need for a thorough inspection of these wear items. Prospective buyers should focus on the rear suspension first. The fractured off‑side rear coil spring will manifest as a pronounced clunk or thump when the vehicle traverses bumps or when the rear wheels are forced over uneven surfaces; the associated mounting points and rear anti‑roll bar bushings should be examined for corrosion or cracking. The thin rear brake pads noted in the 2025 advisory will soon require replacement, and any accompanying brake disc glazing or uneven wear will be evident as a pulsating pedal or squealing noise under moderate braking. The near‑side rear brake cable damage reported in 2024, although not yet affecting parking brake performance, should be inspected for fraying and proper tension, as a compromised cable can lead to reduced parking brake effectiveness. The persistent under‑tray looseness and the recurring fog‑lamp and headlamp aim faults should be rectified to avoid legal non‑compliance and to ensure adequate illumination; visual checks for secure mounting and functional operation of all exterior lamps are essential. Beyond the specific MOT items, a buyer should verify the condition of the tyres, looking for side‑wall cracking, dry rot or uneven tread wear that may have arisen from age rather than mileage. The 12‑volt battery, now eleven years old, should be load‑tested to confirm it can sustain a cold‑crank, especially if the car has spent time standing. All fluid levels—engine oil, coolant, brake fluid and power‑steering fluid—should be inspected for colour and contamination, as time‑based degradation can occur even with modest mileage. Finally, request a full service history and confirm that major services, including timing‑belt or chain replacement (if applicable to this engine), have been logged; any gaps may necessitate proactive replacement to avoid catastrophic failure later in the vehicle’s life.
