2015 Vauxhall Astra 1.6L Diesel · SC15 VVR

The most recent MOT test on the Vauxhall Astra, conducted on 2026-03-05, resulted in a failure due to two major defects: the near-side rear outer side light not functioning and an incorrectly aimed offside front headlamp beam. This marks a significant deviation from the vehicle’s previous MOT history, where the majority of tests passed without defects or only recorded advisories, particularly concerning tyre wear and minor lighting issues. The failure suggests either a recent electrical fault in the rear position lamp circuit or a misalignment issue that may have been overlooked in prior tests, potentially indicating a recurring or newly developed problem. While the 2025 test showed consistent advisories on tyre wear and brake pad thickness, the absence of major failures prior to this suggests that the electrical or optical system may now be at a critical stage requiring immediate attention. The vehicle’s recorded mileage of 162,857 miles at an age of approximately 11 years represents a high annual usage rate of around 14,805 miles per year, which is notably elevated for its age. Such mileage accumulation typically accelerates wear on consumables like brake pads, tyres, and suspension components, as well as potential stress on the drivetrain and electrical systems. The absence of significant mileage gaps—suggesting continuous use rather than prolonged periods of inactivity—may also contribute to accelerated corrosion, particularly in areas prone to standing moisture, such as the brake calipers, exhaust system, and undercarriage. Additionally, high mileage increases the likelihood of fluid degradation over time, including brake fluid, coolant, and transmission fluid, which can lead to reduced effectiveness or system failure if not serviced regularly. Given the recent MOT failure and the recurring advisories on tyre wear and brake pad thickness, the prospective buyer should prioritise a thorough inspection of the rear electrical system, specifically the position lamp circuit and wiring harness, for signs of corrosion, loose connections, or damaged insulation. On a test drive, listen for any unusual electrical noises or flickering in the rear lights, and check for consistent illumination when braking to confirm the brake system’s functionality. The offside rear shock absorber fluid leak is a critical issue, as it indicates a compromised damper, which can lead to poor suspension performance, uneven tyre wear, and reduced vehicle stability. Inspect the rear suspension for excessive play, uneven ride height, or clunking noises during cornering, which may reveal the extent of the fluid loss and potential internal damage to the shock absorber. For the tyres, the advisories from previous MOTs indicate significant wear, particularly on the inner edges of the front and rear tyres, which may suggest overinflation, underinflation, or improper alignment. Measure the tread depth across the tyre’s central and side regions to confirm the wear pattern, as inner-edge balding can compromise traction and increase the risk of hydroplaning. The near-side rear tyre’s severe perishing and cracking may also warrant closer inspection for signs of internal damage or structural compromise, as this can lead to sudden blowouts. Additionally, check for uneven tyre wear, which may indicate misalignment, suspension issues, or steering problems. Given the vehicle’s age and mileage, consider replacing the tyres to ensure safe operation, as the remaining tread depth may not meet modern safety standards or provide adequate grip in adverse conditions. The brake system should also be inspected for signs of corrosion on the discs and calipers, particularly on the near-side rear where the pads were noted to be significantly worn. Binding calipers or corroded discs can lead to uneven braking performance, reduced stopping distances, and premature wear on the remaining pads. Lastly, verify the service history for fluid replacements, including brake fluid, coolant, and transmission fluid, as these should have been serviced at the recommended intervals to prevent degradation and system failure.
