2011 Audi A5 2.0L Diesel · AY52 AAY

The most recent MOT test on 2025-01-31 resulted in a passing outcome, but the preceding history reveals a pattern of persistent and recurring issues that warrant careful attention. While the vehicle achieved a clean test in 2023-04-18, the subsequent failures and advisories indicate a deterioration in both tyre condition and suspension integrity. The near-side front and rear tyres failed the 2025 test due to tread depths below the legal minimum, suggesting either aggressive driving habits or prolonged periods of underinflation, which accelerates tread wear. The 2024-05-02 advisory on tyre wear close to the legal limit alongside suspension arm bush wear—despite not causing excessive movement—demonstrates a gradual but concerning progression in component fatigue, particularly in the lower suspension arms. The 2024-04-25 failure highlighted additional electrical faults with the position and fog lamps, which, while not directly related to mechanical roadworthiness, point to a broader issue with the vehicle’s wiring harness or lamp modules, potentially compounding long-term reliability concerns. The recorded mileage of 144,440 miles for a vehicle aged approximately 15 years reflects a moderate annual usage rate of around 9,629 miles per year, which is within the expected range for a car of this age and class. However, the consistency of the mileage suggests either steady, regular use or a combination of light usage with periods of prolonged inactivity, which can exacerbate wear-related issues. Prolonged standing without maintenance—such as fluid top-ups, brake inspections, or suspension checks—can lead to standing corrosion on brake components, particularly discs and calipers, or fluid degradation in hydraulic systems. Additionally, tyres that remain stationary for extended periods may develop sidewall perishing, cracking, or dry-rotting, which compromises their structural integrity and safety. The absence of a clear spike in mileage indicates no dramatic overuse, but the vehicle’s age and the recurring advisories on suspension and tyre wear suggest that the owner should be cautious about maintaining consistent usage to mitigate further deterioration. For a prospective buyer, the most critical areas to inspect are the tyres, suspension, and electrical systems, as these have been highlighted by the MOT history. Begin with the tyres: visually check for signs of sidewall perishing, cracks, or bulges, and measure the remaining tread depth across the central 3/4 of the tread pattern to ensure uniformity. The near-side front and rear tyres have already failed due to low tread, so any further wear close to the legal limit should be addressed promptly, ideally replacing them before they reach 1.6mm. Listen for unusual suspension noises during the test drive, particularly clunks or rattles when transitioning between bumps or at low speeds, which may indicate worn suspension arm bushes or broken coil spring mounts. Inspect the suspension for uneven ride height or excessive play in the lower arms, as these can lead to misalignment and further tyre wear. The suspension advisories suggest that the lower arms may be nearing the end of their serviceable life, and replacing them could prevent future handling issues and premature tyre wear. Beyond the suspension, the electrical faults from the 2024-04-25 MOT test warrant immediate attention. The non-functional position and fog lamps could stem from faulty wiring, blown bulbs, or a failing lamp module, but the underlying cause should be diagnosed to prevent recurrence. Test the lamps manually by switching them on and off to confirm they respond, then check for continuity in the wiring harnesses connecting to the lamps. If the issue persists, a professional inspection of the lamp assembly and wiring loom is recommended. For the suspension, consider a thorough inspection of the front and rear suspension arms, including the bushings and pins, for signs of excessive wear, cracking, or corrosion. If the advisories suggest significant movement or binding, the arms may require replacement to restore proper alignment and ride comfort. Additionally, with the vehicle’s age and the potential for prolonged standing, check the brake system for signs of corrosion or binding calipers, which can lead to reduced braking performance. Inspect the brake discs for uneven wear, grooves, or corrosion, and ensure the brake fluid is fresh—hydraulic systems should be serviced every 2–3 years or when the fluid appears dark or contaminated. Finally, verify that the service history is up to date, particularly for the suspension, timing belt, and fluid changes, as these are critical for long-term reliability.
