2012 Audi A5 4.2L Petrol · HG61 VLU

A pattern of progressive corrosion and wear on suspension and sub‑frame components defines this Audi A5’s MOT history, with the most recent test on 20 September 2025 still passing but noting an oil leak, a minor central‑exhaust leak and several corrosion advisories. Earlier years show a consistent build‑up of rear sub‑frame rust, front lower suspension mounting corrosion and worn suspension arm pins or bushes, while tyre wear advisories have appeared regularly since 2020. The record shows no outright failures, yet the accumulation of corrosion‑related advisories suggests a gradual deterioration that merits close inspection. At 108 621 mi the car averages roughly 7 800 mi per year, a figure that sits within normal UK usage for a fourteen‑year‑old vehicle. The MOT chronology reveals regular annual testing with no prolonged gaps, indicating the vehicle has been on the road consistently rather than sitting idle for extended periods. This mileage, combined with the age, places typical wear expectations on consumables such as tyres, suspension bushings and the rear sub‑frame, which aligns with the observed advisories. Prospective buyers should focus on the corrosion‑prone areas highlighted in the MOTs. Inspect the rear sub‑frame for any signs of pitting, flaking or weakened joints, and probe the off‑side front lower suspension mounting and off‑side front inner arm dust cover for rust that could compromise mounting integrity. Listen for clunking or knocking over bumps, which may indicate deteriorated ball‑joint dust covers or worn arm pins and bushes that have already been flagged. An oil leak was noted in 2025; locate the source—whether from the valve cover gasket, oil filter housing or oil pan—and assess whether the leak is minor or likely to worsen, as even a small seep can lead to oil‑soaked components and fire risk if left unchecked. Tyre condition also warrants immediate attention. Advisories from 2020 onward point to cracked or perishing sidewalls on the rear tyres and front tyres worn close to the legal limit, with some edge wear noted in 2023. Verify tread depth across all four wheels, look for sidewall cracks, bulges or splits, and confirm that the tyres are not approaching the 1.6 mm legal minimum. Given the age of the car, a full tyre set replacement may be prudent, and checking the condition of the rear coil spring, which was recorded as corroded in 2021, will help ensure the suspension retains its designed ride height and handling characteristics. Addressing these specific items before purchase will provide a clearer picture of the vehicle’s structural soundness and future maintenance needs.
