2017 Audi A5 3.0L Petrol · EX67 DPF

The most recent MOT test on 2025-10-16 resulted in a clean pass, but the vehicle’s history reveals a critical structural failure during the prior MOT on 2025-10-15, where the nearside rear coil spring was found fractured or broken. This major defect indicates a significant structural integrity issue that has not been addressed, which could compromise ride quality and safety over time. While the intervening MOTs from 2023 to 2025 were all passed without defects, the presence of this unrepaired coil spring fracture suggests either incomplete repairs or ongoing neglect, warranting immediate attention. The vehicle’s maintenance trend is therefore unstable, with a clear pattern of deferred or unresolved mechanical issues rather than a consistent improvement. The recorded mileage of 62,726 miles for a 2017 Audi A5 reflects a moderate annual usage rate of approximately 6,970 miles per year, which is within the expected range for its age. However, the gap between the 2021 and 2022 MOTs—nearly two years without testing—could imply prolonged periods of non-use, potentially leading to issues such as brake corrosion from standing, fluid degradation in the cooling and hydraulic systems, or tyre sidewall perishing. Conversely, the rapid accumulation of miles in the final two years suggests increased wear on consumables like brake pads, suspension components, and drivetrain elements, particularly if the vehicle was driven frequently. The combination of moderate mileage and extended idle periods may have accelerated wear in specific systems, necessitating a thorough inspection of those areas. Given the critical coil spring failure recorded in the 2025 MOT, the buyer must prioritise a comprehensive mechanical inspection to confirm the spring’s replacement and ensure the rear suspension is fully repaired. On a test drive, listen for irregular clunking or rattling noises from the rear axle area, particularly when transitioning between bumps or at low speeds, as these could indicate residual movement or misalignment. Inspect the rear suspension for any remaining play or binding, and verify that the wheel alignment has been corrected to prevent uneven tyre wear. Additionally, check for any signs of fluid leaks under the vehicle, as a compromised coil spring could lead to oil or coolant seepage from associated components. The buyer should also address the thin brake pads noted in 2022, as further wear could result in reduced braking performance and increased risk of failure. Brake inspection should include checking for corrosion on discs, warping, or binding calipers, which may require professional assessment. For the broader vehicle assessment, given the moderate mileage and age, the buyer should conduct a visual inspection of the tyres for sidewall cracking or perishing, which can weaken the structure and reduce traction. Ensure the tyres are within legal limits and evenly worn, as the 2022 MOT noted underinflation on the nearside rear tyre, which could have contributed to uneven wear. Check the battery terminals for corrosion and the overall battery health, as prolonged periods of disuse can lead to reduced charge capacity. Fluid levels, particularly the coolant, brake fluid, and differential oil, should be topped up to the manufacturer’s specifications, as standing fluids can degrade over time. Finally, verify that the service history includes scheduled oil changes and fluid servicing, as the Audi A5’s 2.0T engine and transmission require regular maintenance to prevent long-term damage. If the vehicle has been driven primarily for short trips, it may benefit from a flush of the cooling and brake systems to prevent sludge buildup.
