2014 Vauxhall Insignia 2.0L Diesel · ST64 KLO

The vehicle's most recent DVSA examination on 17 January 2026 resulted in a PASS with no defects or advisories recorded, which is a positive immediate indicator. Looking at the broader trend, however, the 2023 test cycle revealed a cluster of braking and structural advisories that, while not severe enough to cause failure, pointed toward developing wear patterns. Notably, the same advisory list appeared on both the 2023 fail and the subsequent pass on the same date, suggesting the fail was driven by items not recorded in the advisory notes but rather rectified during the test or immediately prior to the retest. The subsequent tests in 2024 and 2026 returned clean results with no advisories, indicating that whatever corrective work was undertaken appears to have held, although the absence of advisories does not necessarily mean the underlying components are renewed, merely that they remain within advisory thresholds at the time of test. Overall, the maintenance trajectory shows a stabilising pattern after the 2023 concerns were addressed. The recorded mileage of 136,250 miles over approximately twelve years equates to an annual average of around 11,350 miles, which is broadly typical for a vehicle of this age. There is a noticeable gap between the 2019 and 2021 MOT tests, suggesting either a period of reduced use or a change of keeper during that interval. The mileage progression between recorded tests implies accumulation has continued at a steady, moderate pace without extreme high-use bursts that would disproportionately accelerate wear on drivetrain and suspension components. For a diesel or petrol Insignia of this vintage and mileage, the engine, clutch or automatic transmission, and turbocharging components (if applicable) will have accumulated significant working hours, and timing chains, dual-mass flywheels, and injectors become increasingly common failure points beyond this odometer reading. For a prospective buyer, several areas warrant specific physical inspection and test drive attention based on the historical advisories. The 2021 failure noted an offside rear upper suspension arm ball joint excessively worn, which should be checked for play by hand at the wheel and listened for as a clonking noise over speed humps or uneven surfaces. The 2023 advisories concerning pitted front and rear brake discs, an offside rear binding brake, and fluctuating rear brake performance suggest the rear brake caliper may have been sluggish or seized, and on a test drive you should listen for any rear brake drag or pulling to one side under firm stopping. The recurring rear sub-frame corrosion advisory, first noted in 2022 and again in 2023, demands a close underbody inspection on a ramp to confirm the corrosion has not progressed beyond surface level, as sub-frame integrity is critical for suspension mounting points and structural rigidity. Additionally, the historical oil leak advisory and fuel filler pipe corrosion should prompt inspection of the engine sump, cam cover gasket, and the fuel filler neck area for fresh seepage or active corrosion. Beyond the recorded advisories, age- and mileage-appropriate checks are essential given the vehicle has covered 136,000 miles and stands twelve years old. The brake discs and pads, even if currently within limits, should be expected to require replacement imminently given the 2023 wear patterns. Coolant, brake fluid, and automatic transmission fluid (if fitted) will have been in service for many years and should be replaced on a calendar basis regardless of appearance, as fluid degradation is not visible. Tyres should be examined for sidewall perishing and cracking, which is common on lower-mileage or ageing vehicles, and the 2021 TPMS fault should be verified as rectified with all sensors functioning. The 12V battery should be load-tested, as batteries typically require replacement every five to six years and a failing battery is a common cause of non-start issues and electrical gremlins. Finally, verify a full service history with stamps at appropriate intervals, including cambelt or timing chain inspection records, and ensure the diesel particulate filter (if a diesel model) has a history of motorway use to prevent costly regeneration issues.
