2017 Vauxhall Insignia 1.6L Diesel · DV17 LWL

The Vauxhall Insigna’s most recent MOT test on 2026-02-18 confirms it remains roadworthy at 138,219 miles, with no defects recorded. However, the history reveals a concerning pattern of repeated failures at identical mileages—both 111,659 and 124,994 miles—despite subsequent retests passing. This suggests either a critical component was replaced between failures or the tester’s focus shifted, but the lack of recorded defects in the latest pass does not guarantee underlying issues have been resolved. Buyers should treat the clean pass as provisional until a thorough inspection verifies no recurring faults persist, particularly in areas where failures are historically common. The vehicle’s mileage progression of roughly 15,358 miles annually is unusually high for its age, indicating consistent use rather than sporadic driving. The gap between the 2023 and 2024 tests spans 12 months, with no intermediate mileage recorded, which could imply either accurate annual servicing or a period of standing. The final 13,225 miles between the 2024 failure and the 2026 pass—covering just 18 months—suggests accelerated wear may have been addressed, though without service records, the nature of repairs remains speculative. Given the repeated failures at identical mileages, priority should be given to inspecting components prone to failure in this model, such as the suspension bushes and coil springs, which often degrade predictably. The rear brakes were flagged in the 2023 failure (though no specifics are noted), so binding calipers or uneven wear should be checked. Structural corrosion, particularly around wheel arches and sills, is another critical area given the vehicle’s age; rust can compromise wheel bearings and subframe integrity. Finally, the exhaust system should be examined for leaks or cracks, as catalytic converter failures are a known issue in this range. A pre-purchase inspection should confirm whether the repeated failures were isolated incidents or signs of a broader neglect pattern.
