2015 Audi Q5 2.0L Diesel · OV15 BZX

The most recent MOT test on 10 November 2025 resulted in a pass, but the volume of advisories indicates a worsening maintenance trend regarding the braking system. While previous years showed a relatively clean record with only minor adjustments or isolated wear items, the current status shows systemic degradation across all four brake discs and the rear pads. This suggests a shift from proactive maintenance to a reactive approach, where components are being run to the limit of legal safety rather than being replaced on a scheduled wear-and-tear basis. The vehicle has covered 172,500 miles over its eleven-year lifespan, averaging approximately 15,682 miles per year. This is considerably higher than the typical UK average and places the vehicle in a high-wear category. Such extensive usage typically accelerates the fatigue of drivetrain components, suspension bushings, and engine internals. Prospective buyers should be aware that at this mileage, the vehicle is likely entering a phase where major component failures become more probable, necessitating a rigorous review of the service history to ensure critical long-term maintenance items have been performed. Immediate attention must be given to the braking system. The pitting and scoring of all four brake discs, combined with thin rear pads, indicate that a full brake overhaul is imminent. During a test drive, listen for grinding noises or a pulsing sensation through the brake pedal, which would confirm significant disc warping or surface degradation. Additionally, the 2023 advisory regarding the offside front lower rear suspension arm bush suggests potential wear in the front end. The buyer should listen for clunks or knocks when traversing uneven surfaces or during low-speed manoeuvring, as worn bushes can lead to imprecise steering and accelerated tyre wear. Given the high mileage and age, a thorough physical inspection of the chassis and engine bay is essential. Check for oil leaks around the engine seals and turbocharger, and verify that the coolant is clean and free of contamination. Inspect the tyre sidewalls for cracking and ensure the tread depth is consistent across both axles to rule out alignment issues. Finally, verify the service book for evidence of regular oil changes; at 172,500 miles, any gaps in the service history are a significant risk factor for engine longevity. Ensure the 12V battery is holding a steady charge and that there is no evidence of binding calipers, which can occur if the vehicle has had periods of inactivity despite its high total mileage.
