2012 Vauxhall Corsa 1.2L Diesel · AV12 MLK

The most recent MOT inspection on 25 August 2026 resulted in a failure, indicating a significant and concerning decline in the vehicle's mechanical condition. While the 2025 records showed a passing result, the recent failure for major defects including a split offside outer drive shaft constant velocity boot and excessive black smoke emissions suggests that maintenance standards have lapsed. The trend is clearly worsening, moving from minor advisories regarding shock absorbers and tyres in previous years to critical failures involving the drivetrain and exhaust emissions. This shift implies that the vehicle is currently not in a roadworthy state and requires immediate, potentially costly remedial work to address engine combustion issues and mechanical drive components. With a recorded mileage of 109,825 over approximately 14 years, the vehicle has averaged roughly 7,845 miles per year. This represents typical, relatively light usage for a petrol or diesel hatchback of this age. While lower annual mileage can reduce general engine wear, it often leads to other age-related issues such as component degradation from periods of standing. In this specific case, the mileage is consistent with the observed history of minor leaks and corrosion. However, the recent failure regarding diesel particulate filter emissions suggests that the low-to-moderate usage pattern may have contributed to carbon buildup or soot accumulation within the exhaust system, a common issue when vehicles are not driven frequently enough on motorways to reach optimal operating temperatures. A prospective buyer must exercise extreme caution due to the recurring and escalating nature of the defects. The recent failure for black smoke and emissions inability to be completed is a serious matter that could indicate fuel system issues, faulty injectors, or a compromised diesel particulate filter, which can be expensive to replace. You should listen for rough idling or hesitation under acceleration during a test drive. Furthermore, the split offside drive shaft CV boot is a critical failure; if not addressed, it will lead to the destruction of the drive shaft joint itself. During the test drive, listen for clicking or popping noises when turning the steering wheel at low speeds, which would indicate that the joint has already sustained damage from dirt ingress. Additional attention must be paid to the exhaust system and suspension. The history shows a persistent minor leak at the exhaust flexi-pipe, which has been noted across multiple years, and the recent failure for visible smoke suggests the exhaust system's integrity is compromised. Check for any unusual vibrations or loud droning noises from under the car. The previous advisories regarding misting shock absorbers and corroded coil springs should be physically inspected for significant rust or fluid leakage, as these components affect handling and safety. Finally, ensure the offside headlamp is securely mounted and that the windscreen wipers and lighting systems are fully operational, as these have been points of failure in the past.
