2015 Vauxhall Insignia 2.0L Diesel · DN65 KLC

The defining event in this Insignia's MOT record is a fail in August 2025 caused by fractured rear coil springs on both sides, accompanied by an inoperative horn. The vehicle was re-presented two days later on the same month and passed with no advisories, confirming the suspension and horn issues were rectified. Prior to this, the car had accrued seven consecutive passes from 2019 through 2024 without any recorded defects or advisories, so the rear spring fracture is the only blemish on the otherwise clean paper trail. Both rear springs failing simultaneously is a notable mechanical event rather than a slow, progressive wear item, and while it has been resolved, the buyer should regard rear suspension condition as the primary area of mechanical interest going forward. Against an age of roughly eleven years, the recorded 86,626 miles equates to an annual accumulation of approximately 7,800 miles, which is broadly typical for a vehicle of this vintage and gives no indication of unusually low use or extended periods off the road. There are no significant gaps between annual tests, with the record showing consistent year-on-year presentations from 2019 onwards, suggesting the car has been in regular use throughout. Mileage progression between tests has not produced any extraordinary spikes or plateaus, which is consistent with steady everyday driving rather than commercial or motorway-heavy operation. At this mileage, mid-life consumables such as brake discs, pads, tyres, and ancillary drive belts would reasonably be approaching or past their second replacement cycle on a vehicle of this age. Given the dual rear coil spring failure, a prospective buyer should pay particular attention to the condition of the remaining rear suspension components, including the rear dampers, trailing arms, and any associated bushes, as a fractured spring can sometimes be linked to bottoming-out events or pre-existing weakness in adjacent parts. On a test drive, listen for clonking or knocking noises from the rear over speed humps, uneven road surfaces, and when traversing potholes, and feel for any rear-end instability, excessive bouncing after a single bump, or a noticeably sagging corner. The ride height at each rear corner should be visually checked for symmetry, and the spring seats should be inspected for any signs of coil corrosion or displacement. It is also worth confirming that the horn operation has been fully restored, as a vehicle failing on this item can sometimes be related to steering wheel airbag clockspring or earth connection issues on Insignias of this era. Beyond the suspension, although the braking, steering, exhaust, and emissions records are entirely clean, the buyer should still conduct standard due diligence for a car of this age and mileage. Test the brakes progressively from higher speed to confirm there is no pulling, vibration through the pedal, or binding that would suggest worn front discs or a sticking caliper, and check that the steering remains precise without looseness over bumps, which could indicate worn drop links or front strut top mounts. Inspect the underside visually or via a ramp for any emerging corrosion on subframe mounting points, brake lines, and suspension arms, as surface rust becomes increasingly relevant at this age even though nothing has yet been flagged. Finally, verify the condition and age of the tyres, confirm all warning lamps extinguish promptly after ignition, and ensure the service history paperwork reconciles with the consistent mileage progression shown in the MOT record.
