2018 Audi Q3 2.0L Petrol · DM64 HMM

The most recent DVSA MOT test on 2026-01-02 resulted in a clean pass, marking the vehicle’s first successful inspection since the major failure observed in 2025-01-06, where the offside front coil spring was declared fractured or broken. While this recent outcome is positive, the history reveals a concerning pattern of mechanical issues, particularly the single critical failure of the front coil spring, which suggests underlying wear or manufacturing defects in the suspension system. The subsequent MOTs since then have been largely free of defects, indicating either a resolution of the original problem or a period of reduced stress on the vehicle’s components, but the absence of a replacement or repair record for the coil spring remains a red flag. The advisories from 2024-01-02—front and rear tyres worn close to legal limits—highlight persistent wear that, if unaddressed, could escalate into deeper issues, such as uneven tyre contact patches or premature tread degradation. The recorded mileage of 67,828 miles for an eight-year-old Audi Q3 aligns with a moderate annual usage rate of approximately 8,478 miles per year, which is within the expected range for this vehicle class. However, the gap between the 2020 and 2021 MOTs—over a year without testing—suggests the car may have spent significant periods stationary, particularly if driven infrequently. Standing for extended periods can exacerbate issues like brake disc corrosion, binding caliper pistons, and fluid degradation in the cooling and hydraulic systems, as stagnant fluids accelerate corrosion and seal deterioration. Conversely, if the vehicle has accumulated miles more rapidly than typical, the suspension, drivetrain, and exhaust components may exhibit accelerated wear, particularly in the coil spring failure observed in 2025. The front coil spring’s critical failure underscores the importance of closely monitoring suspension bushings, strut mounts, and alignment for signs of further deterioration. For the prospective buyer, the most urgent immediate concern is the history of the front coil spring failure, which warrants a thorough inspection of the entire suspension system. On a test drive, listen for unusual clunking or rattling noises from the front axle area, especially when cornering or over bumps, as these may indicate further suspension bushings or mounts failing. Inspect the front coil spring visually for any signs of additional damage or deformation, and check for uneven ride height or excessive play in the steering wheel during lateral movements. The tyre advisories from 2024 should prompt a full inspection of tyre tread depth and condition, including checking for edge wear, which could signal alignment or camber issues. Additionally, verify that the front and rear tyres are within legal limits and consider rotating them to ensure even wear. Beyond the suspension, address the potential standing-related risks by checking the brake system for corrosion on discs and pads, ensuring no binding or excessive drag, and inspecting the brake fluid for contamination or low levels, as standing fluid can degrade brake performance over time. In the longer term, the buyer should prioritise a comprehensive mechanical inspection, including the drivetrain, exhaust system, and electrical components, given the vehicle’s age and mileage. Given the coil spring failure, a suspension specialist should assess the condition of the remaining components, such as the front and rear suspension bushes, struts, and control arms, as these are prone to wear and failure in high-mileage vehicles. The tyre wear advisories also suggest it may be prudent to replace the tyres before they reach the legal limit, as further edge wear could indicate underlying suspension or alignment issues that require correction. For fluid systems, consider a full service check, including the cooling system, brake fluid, differential and transmission fluids, as these degrade over time regardless of mileage. Finally, verify the service history for the vehicle, particularly for the coil spring replacement and any suspension-related work, to ensure all necessary maintenance has been completed. If the buyer is concerned about the standing periods, they may also want to check for signs of rust or corrosion on the undercarriage, especially around the wheel arches and exhaust system, as prolonged exposure to moisture can accelerate structural degradation.
