2016 Vauxhall Insignia 2.0L Diesel · SC66 PFX

The most recent DVSA examination recorded on 15 January 2026 returned a pass outcome with no defects or advisories noted, indicating that on the day of testing the vehicle met all statutory roadworthiness requirements. However, when reviewing the broader pattern, the maintenance trend is mixed rather than uniformly stable. A pass was achieved on 14 December 2023, followed by a failure on 18 December 2024 (with no defect details recorded on the official summary), a pass recorded on the same date in December 2024, and then another failure on 18 December 2025, again with no specific defect information captured, before the January 2026 pass. The alternation between pass and fail outcomes within a single twelve-month window suggests that items may have been addressed between tests, but the absence of recorded advisory or failure details makes it difficult to confirm whether these were minor rectifiable items or more substantive mechanical concerns. For a prospective buyer, it would be prudent to obtain the previous advisory and failure documentation directly from the testing garage to establish exactly what was attended to prior to the January 2026 pass. With 128,970 miles accumulated over approximately ten years, the vehicle is averaging around 12,897 miles annually, which is notably above the typical usage profile for a vehicle of this age. While this figure is not extreme, it does indicate above-average consumption that places greater cumulative demand on serviceable components such as braking friction materials, clutch assemblies (on manual variants), suspension bushes, coil springs, and drivetrain ancillaries. Higher annual mileage generally correlates with accelerated wear of consumables, and at this odometer reading items such as timing chains, dual-mass flywheels (where applicable), and turbocharger components on diesel derivatives should be considered as having reached or be approaching their expected service life. There do not appear to be significant gaps in the recorded mileage trajectory, suggesting the car has been in consistent rather than sporadic use, which from a corrosion and standing-start standpoint is generally positive but from a wear standpoint warrants closer mechanical scrutiny. Given the clean advisory record on the most recent test, attention should turn to age- and mileage-appropriate items that are not always captured during an MOT but are nevertheless relevant to a ten-year-old high-mileage vehicle. Tyre condition warrants a thorough physical inspection beyond simply checking tread depth, as the sidewalls should be examined for cracking, perishing, and any bulging that develops with calendar age even when tread remains adequate. Brake discs should be inspected for lipping, surface corrosion, and any signs of binding calipers, particularly given the high cumulative mileage, and a test drive should include several moderate to firm stops from higher speeds to detect any brake shudder, vibration through the pedal, or pulling to one side. The 12V battery should be load-tested, as batteries typically degrade after five to seven years regardless of use, and the charging system should be confirmed as operating within specification. Further checks appropriate to this profile include a comprehensive under-bonnet inspection of fluid condition and levels, with particular attention to engine oil clarity, coolant strength and age, brake fluid hygroscopic content (which should ideally be renewed every two years irrespective of mileage), and the condition of the power steering reservoir where applicable. The exhaust system should be examined for corrosion at joints, mounts, and the catalytic converter area, as ten-year-old vehicles are particularly susceptible to exhaust deterioration from internal moisture and salt exposure. On a test drive, listen for suspension clonks over speed humps and uneven surfaces, which would indicate worn bushes, drop links, or anti-roll bar components, and listen for any whining from the drivetrain or timing chain area that might suggest stretch or guide wear. Finally, verify the service book stamp history to confirm that intervals have been maintained in line with the higher-than-average annual mileage, and consider a compression test or diagnostic scan for any stored fault codes relating to emissions, sensors, or the engine management system before committing to purchase.
