2016 Vauxhall Insignia 2.0L Diesel · DY66 AAF

The latest MOT test on 15 January 2026 resulted in a pass, but the overall maintenance trend is concerning. There is a chronic pattern of fluid leaks, with an oil leak noted consistently since 2023 and a recurring coolant leak appearing in 2021 and 2024. The most recent inspection also reveals a decline in the condition of the front tyres, suggesting that preventative maintenance has lapsed. While the vehicle remains roadworthy, the persistence of these advisories indicates that underlying mechanical issues are being monitored rather than rectified. The recorded mileage of 80,570 miles over approximately ten years reflects a typical annual usage rate of roughly 8,000 miles. This level of use is generally ideal as it avoids the degradation associated with long periods of standing while remaining below the threshold where major drivetrain fatigue typically occurs. However, at this age and mileage, the vehicle is entering a phase where rubber components, suspension bushings, and seals naturally perish, which aligns with the recorded leaks and suspension failures. Prospective buyers must prioritise an inspection of the engine bay and the underside of the sump to assess the severity of the persistent oil leak. The history of coolant leaks requires a thorough check of the radiator, hoses, and expansion tank for any signs of crystallised residue or active dripping. During the test drive, pay close attention to the suspension; the 2023 failure of a fractured offside rear coil spring suggests the chassis is susceptible to fatigue. Listen for knocks or clunks when traversing uneven road surfaces, as this may indicate further worn suspension bushes or failing dampers. The most recent advisories regarding the inner edges of both front tyres are a significant red flag for wheel alignment or tracking issues. This uneven wear pattern will lead to rapid tyre degradation and potential instability if the geometry is not corrected. Carefully inspect the current tread depth and look for scrubbing on the inner sidewalls. Additionally, while rear brake pads were flagged as thin in 2022, you should verify that these have been replaced by checking the remaining friction material through the caliper. Finally, ensure the service history confirms calendar-based fluid changes to mitigate the risks posed by the recorded leaks.
