2021 Audi A5 S Line ED 1 40 Tfsi Mhev SA 2.0L Petrol · NV21 MME

A developing issue with braking component wear is the primary mechanical consideration for this vehicle, as evidenced by the most recent MOT passed on 21 May 2026. While the previous two annual inspections in 2024 and 2025 recorded no defects, the latest test introduced an advisory regarding a worn, pitted, or scored offside front brake disc. This transition from a clean record to a specific component advisory suggests the onset of wear that will require monitoring to ensure it does not progress to a functional failure or affect braking efficiency. The vehicle has covered 40,493 miles over its five-year lifespan, representing an average annual accumulation of approximately 8,099 miles. This usage pattern is consistent with typical UK driving profiles for a vehicle of this age and does not indicate excessive mileage that would typically accelerate the degradation of major drivetrain or suspension components. The steady mileage progression suggests regular use rather than long periods of inactivity, which helps mitigate risks associated with components seizing or fluids degrading due to stagnation. Prospective buyers should focus their physical inspection on the front braking system to address the specific advisory regarding the offside front brake disc. During a test drive, pay close attention to any rhythmic pulsation or judder through the brake pedal when applying pressure at various speeds, as this can indicate disc thickness variation or warping. Additionally, listen for any metallic scraping or squealing noises when braking, which may signal that the disc surface pitting or scoring is accompanied by excessive pad wear or a binding caliper. Beyond the braking system, the absence of recorded defects in the 2024 and 2025 tests indicates that other major systems such as suspension linkages, steering geometry, and exhaust emissions have met minimum regulatory standards in recent years. However, given the recent advisory, a thorough visual inspection of the brake pads and the condition of the surrounding calipers is advisable to ensure the scoring has not led to uneven pad wear or heat-related issues.
