2009 Audi A5 2.0L Diesel · DN58 HHT

Chronic deterioration of the front suspension linkages and a significant instance of structural corrosion define the mechanical history of this vehicle. While it achieved a pass on 2026-04-30, this followed a volatile period in April 2026 involving multiple failures for excessively worn front lower suspension arm ball joints and critical corrosion to the offside rear inner wing which had reduced the rigidity of the assembly. The record shows a worsening trend in suspension wear, with front arm bushes and ball joints appearing as advisories as early as 2024 before escalating into major failures. The recorded mileage of 180,535 miles is consistent with the age of the vehicle, averaging approximately 10,620 miles per year. This steady usage pattern suggests the drivetrain and chassis have been subjected to typical long-term wear. At this mileage, high-wear consumables and supporting components such as engine mounts and cooling system hoses are typically nearing the end of their service life. Given the repeated failures of the front lower suspension arm ball joints and bushes, a test drive should focus on the front end's stability. Listen for knocking or clunking sounds when traversing uneven surfaces or during low-speed cornering. The previous report of an excessively rough steering system and a creaking steering column suggests the steering rack and column should be scrutinized for smoothness and any unusual noises during full lock maneuvers. Particular attention must be paid to the offside rear inner wing to verify the quality of the repair carried out to address the structural corrosion. Inspect the rear tyre sidewalls for the damage noted in the most recent advisories. Ensure there is no steering pull or vibration at motorway speeds, which could indicate that the suspension repairs were not accompanied by a necessary wheel alignment.
