2016 Vauxhall Insignia 1.6L Diesel · FN16 DPZ

The Vauxhall Insignia’s latest MOT test on 2026-05-26 resulted in a passing grade, though it was preceded by a failure in the same month due to persistent tyre wear close to legal limits and functional issues with the near-side windscreen wiper and dipped beam headlamp. The overall maintenance trend over the past two years shows a pattern of recurring tyre-related advisories, particularly on the rear tyres, which were flagged in both 2024 and 2026 tests. While the vehicle passed the 2025 MOT without defects, the presence of multiple advisories in the same areas suggests either suboptimal tyre rotation or alignment practices, or more likely, excessive wear from high-mileage usage. The failure in 2024 also highlighted additional issues with the windscreen washer and headlamp, indicating that while the vehicle may have been roadworthy at the time, these components were not functioning as intended. This history suggests a need for careful attention to tyre management and potential servicing of electrical components, particularly if the vehicle is to be relied upon for regular use. The recorded mileage of 140,207 miles for a vehicle aged approximately ten years represents a relatively high annual mileage of around 14,021 miles per year, which is significantly above the average for its class. Such usage levels typically accelerate wear on consumables like tyres, brakes, suspension components, and fluids, as well as potential stress on drivetrain and structural elements. The absence of significant mileage gaps—particularly if the vehicle has been in continuous use—could imply either a high-performance driving regime or a lack of regular maintenance intervals. However, the rapid accumulation of miles without evident service history or advisories related to drivetrain or suspension wear (e.g., clunking noises, uneven ride height, or fluid leaks) suggests that while the vehicle may have handled wear well, the cumulative effects of high mileage could still require proactive checks. The tyre advisories, in particular, are a red flag, as they often correlate with improper alignment, excessive load, or underinflation, all of which can exacerbate long-term damage. For the prospective buyer, the most critical areas to inspect are the tyres, given the repeated advisories and the high mileage. The near-side front tyre was worn close to the legal limit in 2026, and the rear tyres exhibited significant edge wear in both 2024 and 2026, which may indicate misalignment or uneven load distribution. On a test drive, listen for any signs of uneven tyre wear patterns, such as cupping or excessive shoulder wear, which could suggest suspension or steering issues. Measure the tyre tread depth with a tread depth gauge, and check for sidewall damage or cracking, which can compromise structural integrity and handling. Additionally, verify that all tyres are properly inflated to the manufacturer’s recommended pressure, as underinflation is a common cause of uneven wear. Beyond tyres, inspect the suspension for signs of wear, such as clunking noises when driving over bumps, which could indicate worn suspension bushes, coil springs, or struts. Look for fluid leaks under the vehicle, particularly around the brake fluid reservoir, oil cap, and coolant expansion tank, as these could signal failing seals or fluid degradation. Given the vehicle’s age and the pattern of advisories, it is also advisable to focus on the electrical systems and fluid condition. The repeated failures of the windscreen washer and dipped beam headlamp suggest potential issues with wiring harnesses, fuses, or bulb sockets, which may require professional diagnosis if the vehicle is to be used regularly. Test the washer system by operating the control and checking for fluid spray, and inspect the headlamp assembly for corrosion or binding calipers that could restrict movement. For fluids, check the condition of the brake fluid, engine oil, and coolant, as these can degrade over time even if the vehicle is not driven daily. Brake fluid should be replaced every two years or if it appears dark or contaminated, as this can compromise braking performance. The engine oil should be checked for metal particles or excessive viscosity, and the coolant should be flushed and refilled according to the manufacturer’s recommendations to prevent corrosion and overheating. Finally, consider a thorough inspection of the exhaust system for leaks or structural integrity, as the missing wheel arch and loose wiring from 2024 may indicate ongoing issues that could affect emissions or safety. A thorough visual and functional check of the battery and alternator is also prudent, as the high mileage and potential electrical issues could strain the 12V system over time.
