2010 Vauxhall Insignia 2.0L Diesel · SA60 LMF

The most recent DVSA examination on 4 October 2025 resulted in a pass, though it carries two advisories worth noting: an offside rear coil spring noted as corroded and a rear subframe flagged for corrosion. Reviewing the broader test history, the maintenance trend is best described as broadly stable but with a recurring theme of structural and suspension corrosion that has been progressively flagged since at least 2023. The vehicle passed in 2021 and 2020 with no defects recorded, indicating that the corrosion issues are relatively recent in their MOT visibility, but they have not deteriorated into outright failures on the rear axle. However, a separate Major defect was recorded in October 2024 against the front subframe, which was deemed seriously weakened and clearly required remedial attention prior to the subsequent pass. Overall, the trajectory suggests an older vehicle that is just about holding its roadworthiness but is on a clear downward trajectory in terms of underbody integrity. With 88,033 miles accumulated over approximately 16 years, this Insignia has covered only around 5,500 miles per year on average, which is notably low for the model and its age. Such modest annual usage often reflects a mixture of light running and extended periods of standing, both of which carry their own mechanical consequences. Low-mileage vehicles frequently suffer from aged perishing of rubber components, oxidation of brake discs due to infrequent use, deterioration of brake fluid through calendar ageing rather than mileage, and potential 12V battery failure from irregular charging cycles. Equally, prolonged standing can encourage corrosion in box-section steel and subframe areas, which aligns with the pattern of advisories observed in the MOT record. The structural advisories warrant close physical inspection before purchase. The repeated flagging of the rear subframe, both rear track arms, and both rear trailing arms for corrosion strongly suggests that the underside of this vehicle has been exposed to road salt or moisture over many winters. A prospective buyer should arrange for the car to be examined on a ramp, paying particular attention to the rear subframe mounting points, suspension arm bushes, and coil spring seats for any visible perforation, flaking, or sagging. On a test drive, listen for clonks or rattles from the rear suspension over uneven surfaces, and watch for uneven rear tyre wear, which can indicate geometry distortion from weakened components. The advisories also note an offside rear coil spring corroded, which can lead to spring snapping or vehicle sag on that corner, so the ride height should be compared side to side. The braking history merits equal attention. In 2023 the front brake pads were measured at less than 1.5 mm and categorised as Dangerous, and both front and rear brake discs were flagged for pitting and scoring. Although the 2025 pass implies these were renewed, a buyer should confirm the date and mileage of the most recent brake replacement, including caliper condition. Seized or binding calipers are common on low-mileage cars that have stood idle, and on a test drive any pulling to one side, a spongy pedal, or brake shudder under heavy application should be treated as a red flag. Additionally, given the calendar age, the brake fluid, coolant, and timing chain components should be verified as recently serviced, and the tyres should be examined closely for sidewall cracking, as age-related perishing is more relevant than tread depth on a vehicle of this profile. Confirming full service history and evidence of remedial work to the front subframe addressed in 2024 should be an absolute priority.
