2015 Audi A6 2.0L Diesel · CV15 UCL

Significant concerns regarding braking system integrity and tyre wear patterns define the mechanical history of this vehicle, most notably highlighted by a dangerous failure on 22 July 2026 due to parking brake efficiency falling below 50 percent of the required value. While the vehicle achieved a pass on 29 July 2026, the preceding failure and advisory for thin rear brake pads indicate a recent period of critical component degradation. This follows a trend of recurring tyre-related issues, including a dangerous failure in August 2024 where both front tyres were recorded with exposed ply or cords, suggesting a history of running components beyond their safe operational limits. The recorded mileage of 149,076 miles over approximately eleven years equates to an average annual accumulation of roughly 13,552 miles. This usage profile is relatively high for a vehicle of this age, which typically correlates with increased mechanical wear across consumable items and suspension components. Given the high mileage, the frequency of advisories regarding tyre wear and suspension components is consistent with the expected lifecycle of parts subject to constant road friction and structural loading. Prospective buyers should pay close attention to the braking system and suspension during a test drive. Following the recent dangerous failure regarding the parking brake, it is essential to test the handbrake's holding strength on an incline and check for any unevenness in pedal pressure or binding sensations when applying the foot brake. The history of thin rear pads and the recent parking brake failure necessitates a thorough visual inspection of the rear calipers and discs for excessive wear or uneven surface degradation. Suspension and steering components also require scrutiny based on previous advisories. The 2023 record noted a severely deteriorated swivel boot on the nearside front lower suspension arm ball joint, and the 2024 record flagged light oil misting from the offside front shock absorber. On a test drive, listen for any knocking, clunking, or creaking sounds when navigating uneven surfaces or turning the steering wheel, which could indicate failing ball joints or leaking dampers. Additionally, verify that the vehicle maintains a straight tracking and does not pull to either side, as repeated advisories for tyres wearing on the edges suggest potential alignment or suspension geometry issues.
