2015 Vauxhall Astra 1.6L Diesel · SC65 AAZ

The most recent MOT, dated 3 November 2025, was a pass but carried two advisories – a minor oil leak and a near‑side front tyre approaching the legal tread limit. This follows a failure recorded only three weeks earlier on 23 October 2025, which cited the same oil leak, the same tyre wear, a rear brake disc showing pitting and a dangerous rear‑pad thickness of less than 1.5 mm. The fact that the vehicle cleared the test after the failure indicates that the immediate safety‑critical items – notably the rear pads – have been addressed, but the persistence of the oil leak and tyre wear suggests a maintenance pattern that is stabilising rather than markedly improving. At 89,925 mi for a 2015 model the car averages roughly 8,200 mi per year, which sits comfortably within the typical UK usage envelope. There are no obvious gaps in the recorded mileage, implying regular use rather than prolonged periods of storage. The moderate annual mileage means that consumables such as tyres, brake pads and suspension components will have experienced normal wear, but the relatively low cumulative distance for an eleven‑year‑old vehicle also raises the possibility of age‑related degradation in parts that are not mileage‑dependent, such as rubber seals, battery plates and corrosion‑prone fittings. For a prospective buyer the oil leak noted on two consecutive MOTs should be investigated on the engine bay floor and around the valve cover gasket, oil filter housing and crankcase breather. While the MOT classified it as non‑excessive, any steady seepage can lead to reduced oil level, increased engine wear and, over time, a fire hazard if it reaches hot components. On a test drive listen for a low‑oil‑level warning light, watch the oil pressure gauge and feel for any unusual engine noises such as ticking or knocking that could indicate insufficient lubrication. The front tyre on the near‑side is already close to the legal minimum tread depth; examine both front tyres for uneven wear patterns that might point to mis‑aligned suspension or worn front‑end bushes. The rear brake pads were recorded as dangerously thin in late 2025, so inspect the rear calipers for uneven pad wear, sticking pistons or a soft, spongy pedal feel, and verify that the rear discs are free of deep scoring or corrosion that could compromise braking efficiency. Beyond the recorded defects, age‑related checks are essential. Inspect all tyre sidewalls for cracking, dry‑rot or bulging, especially if the car has spent periods stationary, as rubber deteriorates with time irrespective of mileage. Examine the battery terminals for corrosion and consider a load test, since a twelve‑year‑old battery may be nearing the end of its service life. Verify that the coolant, brake fluid and power‑steering fluid have been replaced within the recommended intervals – fluid degradation can lead to internal corrosion and reduced system performance. Finally, look for any signs of rust on the wheel arches, sills and underbody, and ensure that the exhaust system is free of excessive rust or holes that could affect emissions compliance. Addressing these points will give a clear picture of the car’s current roadworthiness and the likely near‑term maintenance budget.
