2018 Audi A5 2.0L Diesel · Y7 SWG

The most recent MOT test for the 2018 Audi A5 was conducted on 2025-10-15 and resulted in a clean pass, marking a positive turnaround from the previous year’s failure. While the vehicle’s MOT history shows a pattern of advisories related to rear coil springs and front brake fluctuations, the latest test indicates these issues no longer meet the severity thresholds for failure, suggesting either effective corrective action or natural progression of component wear without critical failure. However, the two consecutive advisories from 2024 regarding corroded coil spring mountings—both near and offside—demonstrate persistent structural wear that requires ongoing vigilance. The 2024 failure highlighted a fractured rear coil spring, which would have rendered the vehicle unsafe if left unresolved, underscoring the importance of addressing corrosion and mechanical fatigue in suspension components before they escalate. The recorded mileage of 51,613 miles for an eight-year-old vehicle represents a moderate annual usage rate of approximately 6,452 miles per year, which is typical for its age and class. This usage profile suggests a balance between regular driving and periods of stationary storage, though the absence of a service history or odometer verification means potential discrepancies cannot be ruled out. Higher mileage generally accelerates wear on consumables like brake pads, suspension bushings, and drivetrain components, while lower mileage may indicate less aggressive use but risks from prolonged standing—such as brake disc corrosion, fluid stagnation, or battery degradation. The lack of significant mileage spikes or long gaps between tests does not preclude hidden issues, particularly in high-stress areas like the rear suspension, where corrosion and fatigue are already documented. Given the MOT advisories and failure history, the prospective buyer should prioritise a thorough inspection of the rear suspension and braking system. The corroded coil spring mountings and potential coil spring failure indicate that the vehicle’s suspension geometry may be compromised, leading to uneven ride quality, excessive clunking or rattling when driving over bumps, or a noticeable sagging or uneven ride height on one side. During a test drive, listen for persistent clunking or knocking from the rear, particularly when transitioning over rough terrain, and check for uneven tyre wear that could signal misalignment or suspension misalignment. The fluctuating front brake performance may cause a pulsating or shuddering sensation when applying the pedal, especially under braking, or a binding feel when cornering. Inspect the front brake discs for uneven wear, corrosion, or grooving, and ensure the brake calipers are not binding or seized. For the broader vehicle assessment, the buyer should also verify the condition of the remaining coil springs, as their failure could occur at any time, leading to a sudden loss of ride height and handling instability. Check for any visible signs of oil leaks around the suspension mounts or coil spring bases, which could indicate further corrosion or mechanical failure. The brake system should be thoroughly inspected, including the condition of the brake pads, rotors, and hoses, with particular attention to the rear brakes given the history. Additionally, given the vehicle’s age and the potential for fluid degradation over time, consider having the brake fluid flushed and replaced, as well as the coolant and engine oil checked for contamination or sludge, which can accelerate wear. Finally, while the MOT history is clean for the past two years, a comprehensive pre-purchase inspection should include a check of the tyre sidewall for signs of cracking or perishing, which can weaken the tyre structure and compromise safety, especially if the vehicle has been stationary for extended periods. The 12V battery should also be tested for charge retention and physical condition, as prolonged inactivity can lead to sulphation or corrosion of terminals.
