2012 Vauxhall Insignia 2.0L Diesel · SD62 FWC

The most recent DVSA test dated 26 May 2026 resulted in a failure, with the vehicle presenting a combination of Major and Dangerous defects across multiple safety-critical systems. Notable Major items include corrosion and serious weakening of the nearside front sub-frame, a missing or compromised offside front steering rack gaiter allowing ingress of dirt, and excessively worn front lower suspension arm pins or bushes on both sides. Advisories were also raised for thinning rear brake pads and slightly discoloured front direction indicators. Looking at the broader pattern, the vehicle passed cleanly in 2025 and again in February 2024, but the failure history shows a clear deterioration in 2026, with chassis corrosion, steering protection, and front suspension wear all flagged in a single visit. This indicates a worsening trend rather than stable maintenance, particularly in structural and suspension integrity, which warrants close physical inspection before purchase. With 132,770 miles recorded over approximately 14 years, the vehicle is averaging around 9,484 miles annually, which is broadly typical for its age and usage profile. There are no particularly significant mileage gaps or sudden accumulation spikes visible from the test history, suggesting steady use rather than long periods of standing or extreme high-mileage driving. That said, a 14-year-old Insignia at this mileage has likely reached a stage where general consumable wear, corrosion fatigue, and age-related degradation of rubber and fluid systems become the dominant mechanical concerns, regardless of annual mileage averages. For a prospective buyer, the recent sub-frame corrosion defect is the most pressing structural concern and should be inspected thoroughly on a ramp or over a pit, paying particular attention to mounting points, jacking areas, and any perforation around the front suspension turrets. The worn front suspension arm pins or bushes and the earlier 2022 advisory on coil spring corrosion suggest the front end is due for renewed bushes, springs, and likely dampers; on a test drive, listen for clonking over bumps, imprecise steering through corners, or uneven tyre wear across the front axle. The missing steering rack gaiter should also prompt a check of the rack itself for signs of leaking fluid or contamination, as prolonged dirt ingress accelerates internal wear. Given the dangerous rear brake pad finding in early 2024 and the advisory in 2026 for thinning rear pads again, the rear braking system clearly receives heavy use, so the caliper mechanisms, discs, and handbrake cables should all be inspected for binding or seizure. Beyond the recorded defects, age-related checks remain essential on a vehicle of this profile. Inspect all tyres, including the spare, for sidewall cracking and perishing consistent with fourteen years of service, even where tread depth remains adequate. Examine the exhaust system for corrosion at joints and hangers, and verify that the 12V battery is recent and holding charge, particularly if the vehicle has at times been used only for short journeys. Brake fluid and coolant should have been changed at the recommended calendar intervals regardless of mileage, and the timing belt or chain service history verified in line with manufacturer schedules. Finally, given the high overall mileage, check the automatic or manual transmission for smooth engagement, examine the engine oil on the dipstick for discolouration or creamy residue indicating head gasket or moisture issues, and review the service book stamps to confirm regular oil and filter changes throughout the vehicle's life.
