2012 Vauxhall Astra 1.7L Diesel · ST62 FHD

The most recent DVSA test on 28 October 2022 recorded a failure, principally for a dangerous rear‑tyre tread depth below the legal 1.6 mm, although the test also produced a pass with a series of advisories. Over the preceding eight years the MOT record shows a pattern of recurring issues – a persistent oil leak, progressive wear of front suspension arm bushes, chronic tyre wear on all corners, rear‑coil‑spring corrosion and a fractured rear coil spring in 2018, together with thinning rear brake pads. The frequency of failures has increased, moving from minor advisory items in 2018 and 2020 to a dangerous tyre condition in 2022, indicating that the overall maintenance trajectory is worsening rather than stabilising. At 284,312 mi the Astra averages roughly 20,300 mi per annum, well above the typical UK usage rate of around 10‑12 000 mi per year. This high annual mileage accelerates wear on engine internals, transmission components, suspension bushings, brake discs and pads, and tyre carcasses. The record shows no significant gaps in MOT testing, suggesting the vehicle has been driven consistently rather than sitting idle for long periods, which would otherwise raise concerns about battery sulphation or brake‑disc rust. Nevertheless, the cumulative mileage combined with the age of the car (14 years) means that many wear‑items are likely approaching the end of their service life and will require proactive replacement. A prospective buyer should begin by inspecting the source of the oil leak noted on every MOT since 2020; look for fresh oil stains on the sump, valve‑cover gasket or oil filter housing and monitor the oil level between fills. On a test drive, listen for clunking or knocking when passing bumps, which would confirm the front‑suspension arm bush wear flagged in multiple years, and feel for any steering play or uneven tyre wear that could indicate mis‑alignment. The rear tyre that failed the 2022 test must be replaced immediately, and all four tyres should be examined for tread depth, sidewall cracking and age – tyres older than six years can deteriorate even if the tread appears adequate. Check the rear coil springs for signs of corrosion or fatigue, such as uneven ride height or squeaking when the vehicle is lifted, and verify that the rear brake pads have sufficient thickness; a soft or pulsating pedal, or shudder when braking, would be symptomatic of the previously reported thin pads. Given the vehicle’s age and mileage, a comprehensive service is advisable before purchase. This should include a full oil and filter change, replacement of the front‑suspension arm bushes, a fresh set of tyres, renewal of the rear brake pads and discs, and a thorough inspection of the exhaust system for corrosion that could affect emissions. Verify the condition of the 12 V battery, checking voltage and cranking performance, as prolonged high‑mileage use can accelerate battery depletion. Finally, inspect the chassis and under‑body for rust, especially around the wheel arches and rear‑spring mounting points, and confirm that the service book contains stamps for regular interval servicing, which will give confidence that the engine, timing chain or belt, and coolant have been maintained in line with manufacturer recommendations.
