2018 Audi Q5 2.0L Petrol · AF18 KFE

The most recent MOT test results for the 2018 Audi Q5 reflect a stable maintenance profile, with all tests conducted since the critical failure in February 2022 passing without defects. However, the single major failure in 2022—offside rear coil spring fracture—signifies a critical structural component failure that must be addressed immediately, as coil springs are essential for vehicle stability, ride quality, and load distribution. While subsequent MOTs have been clean, this incident raises concerns about potential underlying wear or fatigue in related suspension components, such as bushings, control arms, or mounting hardware, which may have been compromised by the spring’s failure. The absence of further failures in the intervening years suggests either effective corrective action or that the vehicle has been driven cautiously to mitigate further damage, but a thorough inspection of the suspension system remains imperative. The recorded mileage of 57,091 miles for a vehicle aged eight years represents a moderate annual usage rate of approximately 7,136 miles per annum, which is within the expected range for a Q5 of this vintage. Such mileage typically indicates a balance between regular use and occasional periods of inactivity, though the exact usage pattern cannot be determined from the data alone. Lower mileage could imply reduced wear on consumables like brake pads, tyres, and fluids, while higher mileage might accelerate wear on suspension, drivetrain, and exhaust components. The absence of significant mileage spikes or prolonged periods of high usage does not preclude potential hidden issues, particularly in high-stress areas like the suspension, as the 2022 spring failure suggests. A test drive should focus on monitoring for uneven tyre wear patterns, which could indicate misalignment or suspension misalignment, and listening for unusual clunking or rattling noises from the rear axle or suspension, which may signal loose or worn components. Given the 2022 MOT failure and the critical nature of the offside rear coil spring fracture, the prospective buyer must prioritise a comprehensive mechanical inspection of the suspension system. The coil spring failure itself may have compromised adjacent components, such as the rear suspension bushings, control arms, or mounting brackets, which could exhibit signs of excessive play, corrosion, or fatigue. During a test drive, listen for clunks or rattles when driving over bumps, especially at the rear, as these may indicate loose or worn suspension parts. Additionally, check for uneven tyre wear, which could suggest misalignment or suspension misalignment caused by the failed spring. If the spring has been replaced, verify that the new component is securely mounted and that there are no signs of stress or fatigue in the surrounding suspension geometry. Beyond the suspension, the buyer should also inspect the vehicle’s exhaust system for leaks or emissions-related issues, as the Q5’s catalytic converter and oxygen sensors are critical for compliance and performance. For a vehicle of this age and mileage, the buyer should conduct a thorough physical inspection of several key areas to ensure roadworthiness and longevity. Given the clean MOT history since 2022, focus on the following: inspect the tyres for sidewall perishing, cracks, or tread depth below 1.6mm, as ageing rubber can compromise safety and handling, particularly on older vehicles. Check the 12V battery for signs of corrosion on terminals, swelling, or poor electrical connections, as standing vehicles can lead to battery degradation or failure. The brakes should be examined for corrosion on discs, particularly in areas where water may pool, and for signs of binding or uneven wear, which could indicate caliper issues or warped discs. Fluid levels should be checked—coolant for the cooling system, brake fluid for hydraulic efficiency, and transmission fluid for viscosity and contamination—with a note on the calendar-based degradation of these fluids, especially if the vehicle has been stationary for extended periods. Finally, verify that service records are up to date, particularly for oil changes, timing belt replacement (if applicable), and other scheduled maintenance, as these can prevent costly failures and ensure the vehicle remains reliable.
