2009 Audi Q5 2.0L Petrol · PS09 CSS

The most recent MOT test for this 2009 Audi Q5 was conducted on 2025-10-02, resulting in a passing outcome with a single advisory regarding the rear brake discs being worn, pitted, or scored but not to a point that compromises their structural integrity. Despite this, the vehicle’s MOT history reveals a pattern of recurring critical and advisory failures, particularly in the braking system and drivetrain components, which suggests that while the immediate roadworthiness has been restored, underlying issues persist. The failure in 2023 was particularly severe, with dangerous defects in both the service and parking brake efficiencies and an imminent failure of the offside front drive shaft joint, indicating that the vehicle has not been adequately maintained to prevent progressive wear. This trend of repeated failures—especially the persistent drive shaft boot deterioration and brake system deficiencies—points to either neglect or a lack of proactive servicing, which could escalate into costly repairs if not addressed promptly. The recorded mileage of 101,355 miles for a vehicle aged 17 years represents an annual usage rate of approximately 5,962 miles, which is unusually low for its age. Such low mileage often correlates with periods of prolonged inactivity, where components like brakes, tyres, and suspension can degrade due to standing corrosion, fluid degradation, or mechanical binding. The front brake pads failing to 1.5 mm thickness in 2023 and the subsequent advisory on worn rear discs suggest that the vehicle was either driven infrequently or subjected to heavy braking without adequate maintenance. Tyre sidewall cracking noted in 2024 and 2025 further implies that the vehicle has not been driven regularly enough to dissipate heat and prevent perishing, which can compromise tyre integrity and safety. The rapid accumulation of mileage in some years—particularly if the vehicle was driven more heavily—could have accelerated wear on suspension components, drivetrain seals, and internal brake mechanisms, exacerbating the issues observed in the MOT history. For a prospective buyer, the most critical areas to inspect are the braking system and drivetrain components, given their repeated failures. The front brake pads failing to the minimum legal thickness in 2023 and the persistent advisories on worn brake discs indicate that the pads and discs have been severely under-replaced. On a test drive, listen for uneven brake pedal travel, a spongy or vibrating feel, or a grinding noise when applying the brakes, which could signal warped discs, binding calipers, or internal brake failure. The offside front drive shaft joint failing in 2023 and 2024 is a major concern; inspect the boot for leaks or excessive play, and feel for excessive vibration or clunking when accelerating, especially from a standstill. If the joint is compromised, a replacement could cost several hundred pounds, and delaying this could lead to catastrophic drivetrain failure. Additionally, check for fluid leaks around the fuel tank, as the 2024 failure highlights a potential structural or seal issue that may require repair to prevent fuel contamination of the engine or fire risk. Beyond the immediate defects, this vehicle’s low mileage profile necessitates a thorough check of components that degrade over time due to standing rather than use. Inspect the tyres for sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been left stationary for extended periods. Check the tyre tread depth and look for uneven wear patterns, which may indicate suspension or alignment issues. The 12V battery should be tested for voltage and charge retention, as prolonged inactivity can lead to corrosion on terminals or a weakened battery. Fluid levels, particularly brake fluid, should be checked and topped up if necessary, as standing fluids can degrade over time, compromising brake efficiency. The suspension should be inspected for signs of corrosion on mounting points, particularly around the wheel arches and subframe, and listen for clunks or rattles when driving over bumps, which could indicate worn suspension bushes or broken coil springs. Finally, verify that the service book has been updated for time-based maintenance, such as oil changes and fluid replacements, which are critical for a vehicle of this age and usage profile.
