2012 Vauxhall Astra 2.0L Diesel · GL12 NLV

A dominant concern for this Astra is the progressive deterioration of its braking system, which has been flagged repeatedly across the MOT record. In late 2025 the car failed a test when the off‑side rear pad measured less than 1.5 mm and both rear discs were deemed significantly worn, a dangerous failure that required immediate remedial work. The following day the vehicle passed, yet the same oil‑leak advisory persisted, indicating that while the most recent inspection cleared the car, the brake wear trend remains a key risk factor. At 204,052 mi the Astra has accumulated roughly 14,600 mi per year, a mileage level well above the average for a fourteen‑year‑old family hatchback. Such utilisation accelerates wear on consumables – brake pads and discs, tyres, suspension bushings and engine seals – and reduces the remaining service life of components that are already showing wear in the MOT history. There are no significant gaps in the testing chronology, so the high mileage is a continuous exposure rather than a period of inactivity. When inspecting the brakes, feel for a firm, progressive pedal without any sponginess or pulsation; listen for squeal or grinding that would suggest pad material contacting the disc. Visually examine all four pads for thickness approaching the 1.5 mm danger threshold and inspect the discs for scoring, glazing or excessive rust, especially on the rear side where major failures have been recorded. A thorough check of the brake lines for any signs of oil or fluid leakage around the calipers is also advisable, as the recurring oil‑leak advisory may indicate a source that could affect brake performance. The oil‑leak advisory, present on every MOT since 2020, warrants a close visual inspection of the engine bay for fresh oil deposits around the valve cover, oil filter housing or the rear main seal. Any detectable oil on the ground after a short drive should be investigated. The rear coil‑spring corrosion noted in 2024 and the light misting of oil from the off‑side front shock absorber suggest possible suspension degradation; listen for clunking over bumps, feel for uneven ride height, and check for any oil stains on the shock body. Finally, the tyre wear advisories on all four corners mean the current set is near the legal limit and may be uneven, so a full tyre inspection and likely replacement, together with a wheel‑alignment check, should be part of any pre‑purchase evaluation.
