2020 Audi A5 S Line ED 1 40 Tfsi Mhev SA 2.0L Petrol · WN70 FUD

The most recent MOT test on 2026-04-10 resulted in a clean pass with no recorded defects, marking a positive turnaround following a critical failure in 2023. While the vehicle’s maintenance history shows a pattern of passing previous MOTs, the 2023 test revealed a severe tyre failure—both near- and offside front tyres exhibited exposed ply or cords, a condition that poses an immediate safety risk and is not permissible under UK law. The subsequent advisories in 2024 and 2025, indicating tyre wear close to legal limits, suggest that the tyre failure was not an isolated incident but rather a progression of wear and potential underlying issues, such as misalignment, incorrect tyre pressure, or excessive load distribution. The fact that the vehicle passed the 2026 MOT despite these prior defects implies either a significant improvement in tyre condition or that the advisories were not rectified prior to testing, warranting cautious scrutiny of the tyre history and any corrective actions taken. The recorded mileage of 55,172 miles for a 2020 A5 S Line ED 1 40 TFSI MHEV represents a reasonable annual usage rate of approximately 9,195 miles, which is typical for a vehicle of this age and performance class. However, the mileage data alone does not fully account for periods of inactivity or varying driving conditions, which can accelerate wear in certain systems. For instance, prolonged standing can lead to corrosion in brake components, particularly calipers and discs, or fluid degradation in the cooling and hydraulic systems. Additionally, the rapid progression from a failed MOT to a clean pass in just two years—despite the tyre advisories—could indicate either a well-maintained vehicle with effective tyre management or a history of deferred maintenance that has since been addressed. The advisories suggest that the tyres were not replaced promptly, which may have contributed to the exposed ply condition, highlighting the importance of regular tyre rotation and pressure checks to prevent uneven wear and premature failure. As a prospective buyer, the most critical inspection should focus on the front tyres, given the history of exposed ply and near-legal wear. Visually inspect the tread depth and check for any signs of cord exposure or separation, particularly on the near- and offside front tyres. During a test drive, listen for unusual noises from the front wheels, such as clunking or uneven suspension feedback, which could indicate misalignment or worn suspension components. The exposed ply condition suggests that the tyres were likely worn beyond safe limits, so consider replacing them immediately to avoid further safety risks. Beyond tyres, examine the brake system for signs of corrosion on discs or binding calipers, especially if the vehicle has been stationary for extended periods. Check the brake fluid level and condition, as standing vehicles can lead to fluid degradation, and verify that the service book records any recent brake servicing or fluid top-ups. For the broader vehicle assessment, given the moderate mileage and recent MOT history, practical checks should include verifying the condition of the suspension components, such as bushes and coil springs, which may show signs of wear or fatigue with age. Inspect the exhaust system for leaks or corrosion, as emissions-related advisories could indicate catalytic converter or manifold issues, though none were recorded in the MOT history. Pay particular attention to the 12V battery and associated electrical systems, as prolonged inactivity can lead to corrosion or poor connections. Additionally, since the vehicle is six years old, consider checking the fluid levels and condition of the engine oil, coolant, and brake fluid, as these fluids degrade over time even with regular use. If the vehicle has been driven regularly, the maintenance trend appears more stable, but if there were periods of low usage, ensure that consumables and critical systems are in optimal condition to prevent unexpected failures. Finally, obtain a full service history to confirm that all scheduled maintenance—such as timing belt replacement, spark plug servicing, and fluid changes—has been completed according to the manufacturer’s specifications.
