2015 Audi Q3 2.0L Diesel · GY65 KTF

The vehicle remains roadworthy, though the maintenance history shows a worsening trend regarding braking system component degradation. The most recent test in July 2025 at 72,186 miles flagged the rear brake discs as being worn, pitted, or scored. This follows a similar advisory from August 2024 at 64,871 miles where the nearside rear disc suffered the same issue. While the vehicle has passed these tests, the recurring appearance of disc corrosion suggests the owner is reacting to visible wear rather than performing preventative maintenance. The mileage pattern is consistent with an eleven-year-old vehicle, averaging approximately 6,500 miles per year. The record shows a stable usage interval between 2021 and 2023, where the car covered roughly 6,000 miles annually without recorded defects. Since the 2022 test, the mileage has increased by about 8,000 miles per year. This low annual mileage often leads to surface oxidation on iron brake components and the hardening of rubber suspension components, which explains the pitting noted in the recent MOT entries. A buyer must conduct a thorough physical inspection of the braking assembly to determine the extent of the disc corrosion. Because the tester flagged the rear discs in two consecutive years, the brake rotors should be checked for minimum thickness and surface regularity to ensure they are not beyond. The front brake pads, which were noted as thin in 2023, also require a measurement to confirm they have not reached their wear limit. Since no structural issues or suspension failures were recorded, the primary mechanical concern remains focused on the state of the braking hardware and the potential for seized calipers due to the observed pitting.
