2012 Vauxhall Astra 1.6L Petrol · DB04 ADB

The most recent MOT, dated 1 July 2026, was a pass but recorded a number of advisories, notably a persistent oil leak, a minor exhaust leak and a slightly noisy nearside front wheel bearing. The preceding test on 30 June 2026 had failed on the basis of excessive carbon‑monoxide emissions, indicating that the exhaust leak was serious enough to affect the emissions system. The fact that the vehicle cleared the test a day later suggests that remedial work was carried out, yet the same advisory items re‑appear, showing that the underlying causes have not been fully resolved. Over the past three years the pattern is one of recurring tyre wear, a corroded rear coil spring and a deteriorating windscreen, which points to a maintenance regime that is reactive rather than proactive, with the overall trend stabilising only after the recent failure but still showing several lingering issues. At 94,634 miles the Astra averages roughly 6,800 miles per year, which is typical for a vehicle of its age. The mileage does not indicate any periods of unusually high use that would accelerate wear on major drivetrain components, but the relatively low annual run‑off also suggests the car may have spent extended periods stationary. Prolonged inactivity can exacerbate tyre perishing, battery sulphation and corrosion of suspension parts, all of which are reflected in the MOT advisories for tyre damage and coil‑spring corrosion. Prospective buyers should give particular attention to the oil‑leak source; inspect the valve‑cover gasket, oil pan and any visible oil trails on the under‑tray, and verify that the oil level remains stable after a short drive. The exhaust system must be examined for cracks or loose joints, especially around the manifold and the flex pipe, and a functional emissions test should be performed to confirm that carbon‑monoxide levels are within limits. Listen for a low‑frequency hum or grinding when turning the wheel to detect the nearside front bearing, and check for any play by rocking the wheel at the hub. The front tyres are already close to the legal tread limit and the off‑side front tyre shows damage, while the rear tyres were noted as perishing; replacement of all four tyres is advisable before further use. The windscreen damage should be assessed for cracks that could spread, and the reduced intensity of the nearside front position lamps should be remedied by checking the bulb, socket and wiring to ensure adequate illumination. Given the car’s fourteen‑year age, the 12‑volt battery is likely at the end of its service life and should be load‑tested or replaced. Brake discs should be inspected for surface rust, scoring or uneven wear that can cause shudder, and the calipers examined for signs of sticking, especially after periods of standing. All fluid levels—engine oil, coolant, brake and power‑steering—should be checked for colour and clarity, as time‑based degradation can occur even with modest mileage. Finally, verify that the service book contains regular oil changes, timing‑belt or chain service (if applicable) and any recorded work on the exhaust or suspension, to confirm that the vehicle has been maintained in line with manufacturer recommendations.
