2009 Audi A5 2.0L Diesel · GU59 OLC

The most recent MOT test on 2026-09-01 reveals the vehicle passed, but the preceding two MOTs—on 2022-05-28 and 2022-08-23—highlight a concerning maintenance trend. The 2022-05-28 test failed due to critical issues including a severely worn front inner brake disc, a damaged constant velocity (CV) joint boot allowing dirt ingress, and a near-failure of the near-side front tyre tread, while the 2022-08-23 test recorded persistent advisories such as worn tyres on the edge, a damaged offside rear suspension arm, and steering vibration. These recurring defects suggest either inadequate past maintenance, progressive wear from high mileage, or underlying mechanical fatigue in key components like the suspension and drivetrain. The fact that the latest MOT passed does not erase the history of failures; the CV joint and brake disc issues, in particular, indicate that the vehicle’s drivetrain and braking systems have been under significant stress over time, warranting immediate attention before further deterioration. The recorded mileage of 212,473 miles for a 2009 Audi A5—approximately 12,498 miles per year—is exceptionally high for its age, far exceeding typical usage rates of 10,000 to 15,000 miles annually. Such mileage accumulation typically reflects either heavy, frequent use or prolonged periods of high-performance driving, which accelerates wear on consumables like tyres, brakes, and suspension components. The tyres alone have been subject to repeated advisories of edge wear and near-failure tread depths, indicating either aggressive driving habits, poor alignment, or excessive load distribution. Additionally, the suspension arm damage and steering vibration further suggest that the vehicle has undergone significant stress, potentially from rough road conditions or improper maintenance. The absence of any evident long-term standing periods—where corrosion or fluid degradation might be more pronounced—suggests that the vehicle has been in active service, albeit with wear patterns that demand closer scrutiny. For prospective buyers, the most urgent inspection should focus on the drivetrain and braking systems, given the CV joint boot failure and severely worn brake disc from the 2022 MOT history. On a test drive, listen for unusual noises from the front axle area, such as clunks or grinding when accelerating or turning sharply, which may indicate CV joint or drive shaft issues. Inspect the CV boots for cracks or tears, and check for excessive play or binding in the wheel bearings. The brake system should be tested for smooth operation, without pulsation or shuddering, particularly when applying the pedal firmly. If the CV joint or boot is compromised, the vehicle may exhibit vibration at highway speeds or a lack of smooth power transfer from the engine to the wheels. Additionally, verify the brake discs and pads for even wear and signs of glazing or corrosion, as the 2022 failure highlighted significant disc wear. If the CV joint or brake system is beyond repair, the cost of replacement may be prohibitive, and the vehicle’s long-term reliability could be compromised. Beyond the critical issues, the tyres present a significant concern due to their repeated advisories of edge wear and near-failure tread depths. This pattern suggests either poor alignment, underinflation, or excessive load, which can accelerate tyre degradation. Inspect the tyres for signs of dry rot, sidewall cracking, or internal damage, as these can compromise safety. If the tyres are beyond legal limits or show extensive wear, consider replacing them before the vehicle is put into service, as worn tyres reduce grip and increase the risk of hydroplaning. The suspension advisories, particularly the damaged offside rear arm, also warrant attention. Visually inspect the suspension components for signs of rust, cracks, or excessive play, and listen for unusual clunking or rattling when driving over bumps. If the suspension arm is severely weakened, it could lead to structural instability or failure under load. Finally, given the vehicle’s age and high mileage, check the fluid levels and condition of the engine oil, coolant, and brake fluid, as these can degrade over time even without active use. If the vehicle has been driven regularly, the fluids may be fresh, but if it has stood for extended periods, they should be replaced according to manufacturer recommendations. A thorough service history check, including oil changes and fluid top-ups, would provide further insight into the vehicle’s maintenance record.
