2015 Vauxhall Insignia 2.0L Diesel · SB65 UDU

The 2015 Vauxhall Insignia presents a stable and improving maintenance trend, culminating in a clean pass on 20 November 2025 at 67,205 miles with zero defects recorded. This clean sheet marks a significant turnaround from the November 2023 failure at 53,487 miles, where the tester flagged a fractured offside rear coil spring alongside a misaligned offside headlamp aim. The coil spring fracture was a serious structural fault, yet the subsequent retest on the same day at 53,487 miles passed, indicating the spring was replaced promptly. Suspension wear has not disappeared entirely. In the November 2024 test at 61,840 miles, the tester noted a worn nearside front suspension arm pin or bush, though not yet causing excessive movement. This suggests the front suspension remains a watch point, likely reflecting age-related deterioration rather than neglect. The mileage accumulation tells a consistent story. Between November 2022 at 45,168 miles and November 2024 at 61,840 miles, the car covered 16,672 miles in two years, averaging roughly 8,300 miles annually. The following year saw a slowdown to 5,365 miles between November 2024 and November 2025, bringing the total to 67,205 miles. This pattern sits close to the typical 6,100 miles per year for an eleven-year-old vehicle, with no suspicious gaps or sudden spikes that would suggest odometer tampering or prolonged standing. The steady accumulation supports the view that the car has been used regularly rather than left idle. Brake condition has appeared repeatedly across the record. In November 2022 at 45,168 miles, the tester flagged rear brake pads wearing thin and an offside front service brake binding, albeit not excessively. These items did not recur in subsequent tests, implying they were addressed, but the history warrants a close inspection of rear brake pads, discs, and caliper slide mechanisms during any pre-purchase check. The front caliper binding risk should also be tested on a road drive to confirm no drag or uneven braking persists. Prospective buyers should prioritise a thorough underbody inspection, paying close attention to the condition of both rear coil springs for any signs of corrosion or cracking, the nearside front suspension arm bush for play, and the general state of engine undertrays and covers that have been noted across multiple tests. The headlamp aim issue from 2023 was resolved, but verifying beam alignment and lens condition on both sides remains prudent. Overall, the record reflects a vehicle that has moved from a period of mechanical concern to a clean bill of health, though its eleven-year-old chassis and suspension components demand careful hands-on verification before purchase.
