2011 Vauxhall Insignia 2.0L Diesel · NL61 OBP

The 2011 Vauxhall Insignia presents a broadly stable maintenance trend, though the record reveals a pattern of deferred minor faults rather than proactive servicing. The most recent test on 18 July 2025 at 146,815 miles resulted in a pass, but the tester still flagged a worn, pitted nearside rear brake disc. This advisory carried over from the 2024 failure, where the rear brake pads were below 1.5 mm and both rear discs were likely compromised. The vehicle has now covered 14,000 miles since that 2024 failure, meaning the owner has been driving on a known brake defect for over a year. That is a significant concern. Brake components are consumable, but allowing a known issue to persist across two MOT cycles suggests a reactive rather than preventative approach to maintenance. The mileage accumulation is consistent at roughly 9,800 miles per year, which is typical for a vehicle of this age. There is a notable gap in the record between the clean pass on 24 July 2023 at 118,177 miles and the failed test on 26 July 2024 at 132,995 miles, representing 14,818 miles in just over twelve months. That is a sharp increase compared to the earlier average of around 8,000 miles per year between 2021 and 2023. The sudden spike in use, combined with the cluster of failures in 2024, points to a period of harder driving or neglected servicing. The subsequent drop back to minimal mileage between July 2024 and July 2025, just 13,820 miles, suggests the vehicle may have been used less intensively after the repairs, or possibly stood for periods. A buyer should focus the physical inspection on the rear braking system first. The recurring disc wear and pad degradation indicate the nearside rear caliper may be sticking or the slider pins seizing, a common issue on the Insignia. Check the disc thickness and scoring depth, and inspect the caliper for free movement. The 2024 failure also flagged structural tyre damage, bulges and lumps on both axles, which implies the previous owner was driving on damaged tyres rather than replacing them promptly. Inspect all four tyres for sidewall deformation and uneven wear. The persistent oil leak noted in both 2024 tests warrants a close look at the rocker cover gasket and the turbo oil feed line, as these are known weak points on the 2.0 diesel. Finally, examine the subframes and suspension mounting points for corrosion, particularly around the rear trailing arm bushes, which can deteriorate on higher-mileage examples of this platform.
