2012 Vauxhall Astra 1.7L Diesel · ST12 MKA

A pattern of brake and tyre deterioration sits at the core of this Astra's MOT history. Across nine recorded tests spanning 2016 to 2021, the vehicle passed on seven occasions with no defects recorded, but the two failures both centre on the same mechanical theme. In March 2016 the nearside front brake pads were flagged as below 1.5 mm, classed as a pre-test failure item. More seriously, in April 2019 the vehicle was presented with a dangerous failure for both rear brake discs being seriously weakened, alongside dangerous nearside front tyre tread below 1.6 mm, and major cuts on both rear tyres deep enough to expose ply or cords. That single test therefore combined compromised braking hardware with illegal tyres, indicating that braking and tyre condition warranted immediate attention at that point. The most recent test on 21 October 2021 returned a clean pass with no advisories, and the absence of recorded defects between 2018 and 2021 suggests the roadworthiness presentation stabilised after the 2019 rectification, though the underlying pattern of brake-related wear remains the defining mechanical signature of this car. Annual mileage of roughly 6,948 miles sits broadly in line with what would be expected for a 2012 Astra, neither unusually low nor particularly high. The earliest recorded test is March 2016 and the latest is October 2021, meaning the five-year testing window contains nine entries, which is consistent with the vehicle being in regular use throughout. The mileage accumulation between tests appears steady rather than erratic, with no obvious long lay-up gaps that would raise concerns about dormant corrosion or seized components. At 97,278 miles the vehicle is now approaching the upper end of typical Astra service life, so consumable wear on brakes, tyres, clutches, suspension bushes and exhaust mountings should be anticipated regardless of the MOT record. The relatively modest annual mileage means wear is likely to be progressive rather than aggressive, but components such as rear brake discs have already been replaced once at around 74,000 miles equivalent, which is a useful benchmark. For a prospective buyer, the priority areas to investigate on inspection are those that produced the recorded failures. The April 2019 dangerous failure on both rear brake discs is significant because the Astra of this era is known to suffer rear disc wear, particularly if the handbrake mechanism has been left to seize. On a test drive, listen for any graunching or scraping from the rear on light braking, feel for pulsing through the brake pedal suggesting disc runout, and check that the handbrake holds firmly on an incline without excessive lever travel. Inspect both rear discs through the wheels for a pronounced lip on the outer circumference or visible scoring, and confirm the calipers are retracting freely rather than binding, which would accelerate future disc wear. The earlier nearside front brake pad failure also warrants checking the front discs for wear ridges, as pads and discs are typically replaced together. The tyre-related defects from April 2019 are less mechanically concerning in isolation but indicate the vehicle was being driven with significantly degraded rubber and cuts exposing ply, which compromises structural integrity and wet grip. On any inspection, examine all four tyres for age-related cracking in the sidewalls, uneven shoulder wear that may point to suspension misalignment, and ensure there is sufficient tread depth across the full width. Beyond the flagged items, an Astra of this age and mileage should be assessed for the usual Vauxhall weak points: knocking or clonking from the front suspension over speed humps suggests worn lower wishbone bushes or anti-roll bar drop links, while any pulling under braking or steering wander points to worn front suspension arms or top mounts. Check for oil seepage from the rocker cover gasket, coolant leaks around the thermostat housing, and condition of the exhaust flexi joint and rear silencer, as these are typical MOT advisory candidates on higher-mileage Astras and would help anticipate the next test outcome.
