2018 Audi Q5 2.0L Diesel · LS18 OUF

The most recent MOT test for the 2018 Audi Q5 recorded a passing result on 2026-03-27, marking a significant improvement from its previous failure on 2026-03-26, where two dangerous defects—offside rear brake pads below the legal minimum thickness and a compromised offside rear constant velocity (CV) boot—were identified. While the 2025 MOTs predominantly featured advisories related to tyre wear and minor damage, the absence of any further failures since 2024 suggests a positive maintenance trend, though the CV joint boot issue from the latest failure indicates ongoing wear that requires attention. The vehicle’s history shows a pattern of advisories rather than outright failures, with the most critical issues resolved or corrected, though the CV boot failure underscores the need for proactive servicing to prevent further ingress of contaminants into the drivetrain. The 49,079 recorded miles for this eight-year-old Q5 represent a reasonable annual usage rate of approximately 6,135 miles per year, which is typical for its age and class. Such mileage does not necessarily indicate excessive wear, but it does imply consistent exposure to road conditions that can accelerate component fatigue, particularly in suspension, brakes, and drivetrain systems. The absence of significant mileage gaps suggests the vehicle has been in regular use, which may explain the recurring tyre wear advisories—particularly the edge wear and near-legal limits noted in multiple MOTs—indicating potential alignment or camber issues or uneven tyre pressure distribution. However, without evidence of rapid mileage accumulation, the wear profile does not yet suggest catastrophic failure, though the CV boot failure highlights the importance of monitoring drivetrain integrity over time. For the prospective buyer, the tyre advisories present a straightforward but critical inspection point. The near-legal wear and edge wear on multiple tyres suggest checking for uneven tread wear patterns, which could indicate misalignment, incorrect tyre pressure, or suspension issues. On a test drive, listen for any clunking or rattling in the suspension, particularly when cornering or over bumps, as this may correlate with worn suspension bushes or coil springs. Inspect the offside rear CV joint boot for any signs of leakage or damage, and listen for unusual noises when accelerating or turning, which could signal a failing seal allowing dirt or moisture into the joint. The brake pads failing the 2026 MOT at less than 1.5 mm thickness are a dangerous defect requiring immediate replacement, as insufficient friction material increases stopping distances and braking efficiency. Beyond the immediate concerns, the vehicle’s age and usage profile warrant a thorough physical inspection for age-related degradation. Given the 49,079 miles and eight years of service, check the tyre sidewalls for signs of perishing or cracking, which can compromise structural integrity and reduce tread depth if already worn. Inspect the battery terminals and cables for corrosion, as standing vehicles over prolonged periods can accelerate battery degradation, and test the 12V output to ensure it holds charge without excessive resistance. The windscreen wiper failure from 2025 highlights the need to replace the wiper blade or motor if the vehicle is to remain roadworthy, as effective windscreen clearance is a mandatory safety requirement. Additionally, verify that the service history aligns with manufacturer recommendations, particularly for fluid servicing—such as brake fluid, coolant, and differential fluid—due to their calendar-based degradation, even if mileage is moderate. Finally, a visual inspection of the exhaust system for corrosion or leaks, and a check of the exhaust emissions system for any unusual smells or smoke, should be conducted to ensure compliance with current emissions standards.
