2016 Vauxhall Insignia 2.0L Diesel · DV66 UNP

The most recent MOT recorded on 30 July 2026 resulted in a failure, the test citing a major fault for front‑brake imbalance across the axle and advisories for thin linings on both front brake pads. Earlier tests in the same year showed a pass, but the presence of a failure this year marks a clear deterioration from the clean or advisory‑only results of the preceding three years, indicating that the vehicle’s maintenance trajectory is now worsening rather than remaining stable. At 108,928 miles the 2016 Vauxhall Insignia averages roughly 10,900 miles per annum, which sits comfortably within the normal usage band for a ten‑year‑old family car. There are no obvious mileage gaps in the recorded history, suggesting the vehicle has not endured prolonged periods of inactivity that could exacerbate age‑related decay, but the cumulative distance does imply that wear items such as suspension bushings, steering components and drivetrain bearings will be approaching the latter stages of their service lives. Prospective buyers should give the front‑brake system immediate attention. Verify that the pads on both sides are replaced with a matching set and inspect the discs for scoring, glazing or uneven wear that could be contributing to the reported imbalance. During a test drive listen for any pulsation or shudder through the pedal, and feel for a soft or spongy pedal travel that may indicate a leaking caliper or air in the hydraulic line. The tyre advisories from 2024 and 2025 show all four tyres approaching the legal tread limit and exhibiting edge wear, so a full set replacement is advisable; inspect the sidewalls for cracking or dry‑rot, especially given the vehicle’s ten‑year age, and ensure the new tyres are correctly balanced and aligned to prevent premature wear recurrence. The lower rear suspension arms were noted as corroded but not structurally compromised; a visual inspection of the arm tubes, bushings and mounting points for any progression of rust or loss of material is prudent, and any excessive play in the rear wheel bearings or a clunk when applying load over bumps should be reported. Beyond the specific faults, a ten‑year‑old car warrants a thorough age‑related check. Confirm the health of the 12‑volt battery, looking for reduced cranking power or swollen cells, and consider a load test. Examine all fluid levels – engine oil, coolant, brake fluid and power‑steering fluid – and verify that they have been changed at appropriate intervals, as fluids degrade with time regardless of mileage. Inspect the exhaust system for corrosion or cracks, and ensure the emission control components such as the catalytic converter are intact. Finally, review the service book for evidence of regular oil changes, timing‑belt or chain service (if applicable), and any recorded replacement of wear items; a well‑documented service history will help mitigate the concerns raised by the recent brake failure.
