2018 Audi Q3 2.0L Diesel · KX18 BGS

A recurring pattern of component wear, specifically regarding the braking system and tyre condition, defines the mechanical profile of this Audi Q3. While the vehicle passed its most recent inspection on 4 November 2025, the record shows a persistent trend of advisories related to the rear braking assembly. The 2025 test flagged both the offside rear brake disc as being worn, pitted, or scored and the rear brake pads as wearing thin, which mirrors an advisory from the 2022 inspection concerning the offside rear disc. This indicates a continuing requirement for attention to the rear braking components to prevent future failure. The vehicle has covered 58,961 miles over approximately eight years, representing an average annual accumulation of roughly 7,370 miles. This usage rate is consistent with typical light-to-moderate driving patterns for a vehicle of this age. From a mechanical standpoint, this level of mileage suggests that while major drivetrain components may not have reached high-mileage thresholds, consumables such as tyres, brake pads, and discs are subject to standard age-related degradation and wear. The 2023 advisory regarding perishing and cracking on all four tyres is consistent with a vehicle that is driven at these lower annual mileages, where rubber compounds can degrade due to age rather than just tread wear. Prospective buyers should pay close attention to the braking performance during a test drive, specifically looking for any pulsation or judder through the brake pedal, which could indicate further deterioration of the rear discs. Given the advisory regarding the central rear prop shaft joint in 2023, it is advisable to listen for any rhythmic humming, vibration, or clunking noises emanating from the centre of the vehicle, particularly during acceleration or when cruising at higher speeds. Any irregular vibrations felt through the floorpan or seat could be indicative of increased play in that joint. Regarding the tyres, although the 2023 advisories for cracking and perishing were recorded, the buyer should physically inspect the sidewalls and tread grooves of all four tyres for any signs of continued age-related cracking or uneven wear patterns. Check for any pulling to one side during straight-line driving, which might suggest that the previous tyre issues or suspension components have affected the wheel alignment. Focus the inspection on the rear braking hardware to ensure the pitted or scored discs noted in the latest test have been addressed or are not approaching a level that requires immediate replacement.
