2015 Audi Q5 3.0L Diesel · DF64 ABK

The latest MOT test results for the 2015 Audi Q5 reflect a stable but concerning maintenance pattern, with the most recent inspection on 2026-01-13 yielding a clean pass apart from several advisories that suggest gradual wear and minor mechanical concerns. The advisories on the front lower suspension arms—particularly the worn but non-excessive movement of the pin or bush in both offside and nearside positions—indicate that these components are approaching the end of their serviceable lifespan, which could lead to increased play, clunking noises, or reduced ride comfort over time. Additionally, the insecure bump stop or dust cover on the near-side rear shock absorber is a minor but critical oversight, as it may allow contaminants to enter the shock, compromising its hydraulic function and potentially causing premature failure. The presence of an oil leak advisory from 2025-01-10, though not excessive, suggests a persistent issue that should be addressed promptly, as it may stem from a failing seal or gasket in the engine bay, transmission, or exhaust system. The failure in 2024-01-12—particularly the critical brake pad thickness below 1.5 mm—demands immediate attention, as this is a safety-critical failure that must be rectified before the vehicle is re-tested. Overall, the trend shows that while the vehicle has maintained roadworthiness through MOTs, the advisories and recurring issues highlight a need for proactive maintenance to prevent escalation into more serious mechanical or safety-related problems. The recorded mileage of 125,341 miles for a 11-year-old Q5 is consistent with a moderate annual usage rate of approximately 11,395 miles per year, which is typical for its age and class. This level of mileage does not necessarily indicate excessive wear if the vehicle has been well-maintained, but it does suggest that consumable items like brake pads, filters, and fluids have been subjected to regular replacement cycles. However, the absence of significant mileage gaps—such as long periods of inactivity—could also imply that the vehicle has been driven frequently, potentially accelerating wear on suspension components, drivetrain elements, and internal engine parts. For example, the suspension advisories may reflect cumulative stress from frequent use, while the oil leak could be exacerbated by prolonged operation at high temperatures. It is worth noting that lower mileage figures might suggest periods of standing, which can lead to specific issues such as brake disc corrosion from rust, standing corrosion on suspension components, or fluid degradation in seals and hoses due to stagnation. Given the MOT history and recorded mileage, the prospective buyer should conduct a thorough physical inspection to address the identified advisories and ensure the vehicle’s long-term reliability. First and foremost, the brake system must be prioritised, with immediate attention required to replace the front brake pads to a thickness of at least 1.5 mm. Inspect the brake discs for warping, scoring, or excessive glazing, and check for signs of binding or corrosion on the calipers, which could indicate standing corrosion or hydraulic issues. Listen for any grinding noises during braking, which would confirm pad wear below the legal minimum. The suspension advisories necessitate a closer inspection of the front lower arms, particularly the bushings and pins, for signs of excessive play, cracks, or oil staining. Clunking noises when driving over bumps or uneven surfaces, especially in the front or rear suspension, would confirm wear progression. Additionally, the oil leak should be traced to its source—common culprits include the valve cover gasket, oil filter housing gasket, or transmission fluid cooler lines—and repaired to prevent further contamination of the engine oil. The insecure shock absorber bump stop or dust cover should be secured or replaced to prevent contamination and ensure proper shock operation. For the buyer’s practical inspection, focus on the following areas beyond the MOT advisories: check the tyre tread depth, ensuring it meets the legal minimum of 1.6 mm across the central ¾ of the tread, and inspect for uneven wear patterns that may indicate suspension or alignment issues. Look for sidewall cracking or perishing, which can occur with age even at moderate mileage, particularly if the vehicle has been stored in a warm environment. Verify the condition of the 12V battery, as standing vehicles can suffer from sulphation or terminal corrosion, which may require a deep discharge test or replacement if the battery is over 10 years old. Inspect the exhaust system for leaks, rust, or structural integrity, as corrosion can compromise emissions performance and safety. Check the fluid levels, including the engine oil (ensure it meets the manufacturer’s viscosity specification for the age of the vehicle), transmission fluid (for a dark, burnt smell if degraded), and brake fluid (for a dark, syrupy consistency, indicating age). Finally, verify that the service book or maintenance records are up to date, particularly for oil changes, timing belt replacement (if applicable), and suspension component servicing, as these are critical for preventing future failures. Given the vehicle’s age and mileage, a comprehensive pre-purchase inspection by a qualified mechanic is strongly recommended to confirm the advisories and identify any hidden issues that may not be apparent during a visual inspection.
