2015 Vauxhall Insignia 2.0L Diesel · LL64 KCV

The latest MOT test on 14 August 2026 passed with no recorded defects, which is a positive indicator of its current roadworthiness. However, the history reveals a recurring and concerning pattern with the rear coil springs, which failed on two separate occasions in 2024 and 2023 due to fracture. While the advisories for tyre wear have been addressed—evidenced by the absence of such notes in the last two tests—the repeated coil spring failures suggest a potential weakness in the rear suspension that may require closer inspection. The trend is not worsening in terms of frequency of failures, but the structural integrity of the suspension remains a key watchpoint. At 160,220 miles over 11 years, this Insignia has covered an average of around 14,565 miles annually, which is on the higher side for a vehicle of its age. Such consistent, high-mileage usage typically accelerates wear on consumables like tyres, brake components, and suspension bushes, as well as placing greater demand on the drivetrain and engine ancillaries. The absence of long periods of inactivity reduces the risk of standing-related issues such as brake caliper binding or fluid degradation from lack of use, but it does mean that mechanical fatigue is more likely to be a factor in its overall condition. Given the history of fractured rear coil springs, a thorough inspection of the entire rear suspension is essential. Check for signs of corrosion or fatigue on both coil springs, as well as the condition of the shock absorbers, bushes, and mountings, as these components often degrade in tandem. Listen for clunks or knocks over rough surfaces, which could indicate worn or damaged suspension components, and observe the vehicle’s stance for any uneven ride height. The tyres should also be scrutinised for uneven wear patterns, which may point to alignment or suspension issues, even if the tread depth is currently legal. Additionally, with this mileage, the brake system warrants close attention. The advisories for thin brake pads in 2023 suggest that the braking components have been under consistent stress, so inspect the discs for scoring, grooving, or excessive lip formation, and check for any signs of binding or uneven wear. Fluid levels and condition, particularly the brake fluid and coolant, should be verified, as high-mileage vehicles often require more frequent changes to maintain optimal performance. Finally, assess the overall underseal and structural areas for corrosion, as rust can compromise the vehicle’s integrity, especially in older, high-mileage examples.
