2010 Vauxhall Insignia 2.0L Diesel · BD10 ONT

The Vauxhall Insignia’s most recent MOT test on 2025-02-27 at 110,630 miles passed without defects, but the immediate preceding test on 2025-01-28 at 110,564 miles failed—despite no recorded issues. This abrupt reversal suggests either a late-stage pre-test service or a minor oversight in the final inspection, though the absence of defects in the February pass implies no critical failures were present. The pattern of two consecutive tests in early 2025 (both at over 110,000 miles) with no warnings or advisories indicates the vehicle’s core systems were stable during that period. However, the lack of any recorded faults across five tests spanning nearly two years raises questions about the thoroughness of previous inspections, as even minor recurring issues—such as brake wear or suspension wear—are typically flagged in MOTs of this age. The recorded mileage of 110,630 miles over 16 years aligns closely with the average annual distance of 6,914 miles, suggesting consistent, moderate use without prolonged periods of neglect or rapid acceleration in wear. There are no gaps longer than a year between tests, which is commendable, though the clustering of two tests in early 2025—just 59 miles apart—implies either a rushed pre-test service or an attempt to avoid a failure. The absence of mileage jumps or extended periods of inactivity means high-mileage components like timing belts, suspension bushes, and brake calipers have likely seen steady use rather than sporadic heavy loads or prolonged storage. Given the lack of recorded defects, a buyer should prioritise an independent inspection of the suspension geometry, particularly the rear bushings and coil springs, which are common failure points on this model at this mileage. The brakes, while not explicitly flagged, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle was driven hard between tests. Structural integrity should be checked for corrosion in wheel arches, sills, and subframes, as 16 years of exposure to UK road conditions often accelerates rust in these areas. Finally, the engine bay should be inspected for fluid leaks, as the absence of advisories does not preclude gradual degradation in hoses, belts, or the cooling system.
