2009 Mazda 2 1.4L Diesel · ST09 LGC

The most recent MOT test for this 2009 Mazda, conducted on 2023-11-01, resulted in a clean pass with no recorded defects, marking a significant improvement from its preceding failures. However, the vehicle’s MOT history reveals a pattern of persistent and worsening mechanical issues, particularly in the suspension, brakes, wheel bearings, and structural integrity. While the latest test shows stability, the earlier failures—including major defects such as excessive brake fluctuation, corroded brake pipes, worn suspension components, and rough wheel bearings—demonstrate a history of neglect or deferred maintenance that has led to critical wear progression. The advisories from previous MOTs, such as corroded sub-frames and underseal applications, underscore ongoing corrosion risks that, if left unaddressed, could compromise long-term structural reliability. The recorded mileage of 85,791 miles for a vehicle aged 17 years represents an unusually low annual usage rate of approximately 5,047 miles per year, which is far below the typical expectations for a car of this age. Such low mileage often reflects periods of inactivity, particularly if the vehicle has been stored for extended durations, leading to accelerated degradation from factors like standing corrosion, fluid degradation, and tyre perishing. The suspension and brake systems, in particular, are more susceptible to corrosion and fluid leaks when a vehicle stands idle for prolonged periods, as seen in the repeated MOT failures related to ball joints, shock absorbers, and brake pipe corrosion. Additionally, the lack of regular servicing during these gaps could exacerbate internal wear in components like wheel bearings and engine systems, as evidenced by the 2021 and 2022 failures. Given the vehicle’s history of MOT failures and the low mileage, the prospective buyer should conduct a thorough inspection focusing on the suspension, brakes, and structural components. On a test drive, listen for unusual noises such as clunks or rattles from the suspension, which may indicate worn ball joints or damaged coil springs, and check for uneven tyre wear patterns that could signal misalignment or suspension issues. Inspect the brake system for any signs of pulsation or shuddering, which may suggest binding calipers or warped discs, and verify that the brake pipes are free of leaks or corrosion. The rear cills near the jacking points should be closely examined for signs of severe corrosion, as the 2020 and 2021 MOT failures highlighted significant rigidity concerns. Additionally, since the vehicle has been stationary for extended periods, inspect the tyres for sidewall cracking or perishing, which can compromise their structural integrity, and check the 12V battery for signs of weakness or corrosion, as standing vehicles are prone to battery drain. For fluid systems, the buyer should consider the calendar-based servicing of brake fluid, which should be replaced every 2–3 years due to moisture absorption, even if mileage is low. The engine oil and coolant should also be checked for signs of degradation, as prolonged idling can accelerate sludge formation and corrosion in the cooling system. Finally, verify that the service history is up to date, particularly for the suspension and brake components, as the vehicle’s history suggests these areas require proactive maintenance. If possible, obtain a pre-purchase inspection by a qualified mechanic to assess the extent of corrosion, fluid condition, and internal component wear beyond what the MOT records reveal.
