2008 Audi A5 1.8L Petrol · SD08 KOU

Corrosion on the subframe mounting areas and a recurring history of fluid leaks define the mechanical profile of this Audi A5. While the most recent MOT on 28 March 2024 resulted in a pass, the record shows a persistent pattern of issues involving oil leaks, coolant leaks, and exhaust gas leaks. The structural integrity of the subframe was flagged for corrosion in the latest test, and while not considered excessive at that time, this follows a history of significant mechanical failures, including a fractured offside front coil spring and a dangerous tyre tread depth deficiency in previous years. The vehicle has covered 87,385 miles over its 18-year lifespan, which equates to an average annual accumulation of approximately 4,855 miles. This is a low rate of mileage for a vehicle of this age. Such a usage pattern can sometimes lead to specific mechanical concerns, as components like suspension bushes, seals, and rubber hoses may experience degradation from age and environmental exposure rather than high-frequency mechanical wear. The MOT history reflects this, with multiple advisories regarding tyre wear and fluid management appearing even when mileage was not high. A prospective buyer should pay close attention to the underside of the vehicle and the engine bay. The history of oil and coolant leaks, alongside the recent advisory for a minor exhaust gas leak, necessitates a thorough inspection for active weeping or staining. On a test drive, listen for any changes in exhaust note that might indicate the leak is worsening, and monitor the engine temperature gauge closely. The advisory regarding subframe mounting area corrosion should be investigated to determine if the oxidation is stable or progressing, as this can impact long-term structural integrity. Suspension and steering components also require careful evaluation. Previous tests have flagged play in the steering rack inner joints and slight play in the front lower suspension arm ball joints. During the test drive, pay attention to the steering feel for any vagueness or heavy spots, and listen for knocks, clunks, or metallic rapping when driving over uneven surfaces or speed bumps, which could indicate worn bushes or ball joints. Additionally, given the history of tyre advisories and the previous failure for a fractured coil spring, the condition of all suspension springs and the remaining tread and edge wear on the tyres should be verified against the current legal standards.
