2012 Audi Q5 2.0L Diesel · AP58 FER

The latest MOT test on 2025-10-02 resulted in a passing grade, though it revealed persistent advisories that indicate ongoing wear and potential long-term concerns. The vehicle’s maintenance history shows a pattern of recurring issues, particularly in the suspension and braking systems, with no major failures resolved beyond the 2024 test. The advisories from 2024 and 2025 on the front lower suspension arms—both near and offside—suggest progressive wear in the pin or bush components, which, while not yet severe enough to cause excessive movement, may lead to increased play or binding if left unattended. The rear brake discs and pads also show consistent thinning, with the 2024 and 2025 tests highlighting this as an advisory rather than a failure, but the wear trajectory warrants closer attention. The 2024 failure due to a split or insecure constant velocity (CV) boot on the nearside front drive shaft joint is a critical mechanical concern, as it compromises the integrity of the drivetrain seal, risking contamination and accelerated joint failure. This defect should be addressed promptly to prevent further damage to the differential and transmission. The vehicle’s recorded mileage of 113,642 miles at the time of this assessment represents a moderate annual usage rate of approximately 8,117 miles per year, which is typical for a 14-year-old car with this level of mileage. The consistent mileage accumulation suggests regular, albeit not extreme, driving conditions, though the gaps between MOT tests—particularly the two-year interval between 2023 and 2025—may indicate periods of prolonged inactivity. Prolonged standing without maintenance can exacerbate issues like brake corrosion, suspension binding, and fluid degradation, so any extended periods of disuse should be factored into the inspection. The wear patterns observed in the suspension and braking systems are often exacerbated by such idle conditions, as components like brake discs and pads corrode more rapidly when not actively engaged, while suspension elements may stiffen or seize due to lack of movement. For a prospective buyer, the most urgent actions should focus on the CV boot failure and the progressive suspension wear. The split CV boot on the nearside front drive shaft joint must be repaired or replaced immediately to prevent contamination of the differential and potential transmission damage. During a test drive, listen for unusual noises from the front axle area, such as whining or grinding, which could indicate a failing joint or seal. Inspect the boot visually for any signs of tears or leaks, and check for excessive play or vibration in the front wheels, which may signal further drivetrain issues. Regarding the suspension advisories, the worn suspension arms should be inspected for signs of excessive movement or binding, particularly when the vehicle is driven over bumps or corners. Look for uneven tyre wear patterns, which may indicate misalignment caused by suspension misalignment, and listen for clunking noises from the front suspension when driving over rough roads. If the arms are confirmed to be worn beyond the advisory limits, replacement may be necessary to restore ride quality and handling stability. In addition to the immediate concerns, a thorough physical inspection should address broader age-related and mileage-related checks. Given the vehicle’s age and mileage, examine the tyres for signs of sidewall cracking or perishing, which can compromise structural integrity and safety. Check the tread depth and wear patterns, ensuring they meet legal requirements and that the tyres are evenly worn. Inspect the brake system for signs of corrosion on the discs, particularly on the rear, where the advisories suggest thinning. Look for any binding or roughness in the calipers or brake pads, which could indicate poor braking performance or hydraulic issues. The brake fluid should be checked for contamination or moisture, as this can lead to brake failure, and a fluid flush may be recommended if the vehicle has been stationary for extended periods. The battery should be tested for voltage and overall health, especially if the vehicle has been idle for long periods, as standing corrosion or a failing battery can lead to electrical gremlins or starting difficulties. Finally, verify that all fluids—oil, coolant, and transmission fluid—are topped up and free from contamination, as these can degrade over time, even with regular use. Calendar-based servicing intervals should also be adhered to, with the service book checked for any outstanding recommendations, particularly for suspension and drivetrain components given the history of wear.
