2018 Audi A3 1.5L Petrol · OW67 DFP

Recurring brake and tyre wear patterns define the technical history of this Audi A3, which concluded its latest inspection on 21 October 2025 with a pass following a failure for electronic system faults. While the vehicle has maintained a consistent testing cycle, the recent failure highlights a shift from simple consumable wear to more complex electrical issues, specifically involving the supplementary restraint system and the tyre pressure monitoring system. The presence of repeated advisories regarding rear brake components and tyre edge wear suggests a persistent trend of accelerated degradation in these areas, indicating that these parts require frequent monitoring rather than long-term resolution. Accumulating 109,168 miles over eight years results in an average annual usage of approximately 13,646 miles, placing this vehicle significantly above the typical usage profile for a passenger car of this class. This high-mileage history implies that the drivetrain, suspension, and chassis components have been subjected to sustained operational stress rather than the cycles of stagnation often seen in lower-mileage examples. Prospective buyers should anticipate that the increased frequency of road use has accelerated the natural fatigue of rubber bushings, wheel bearings, and suspension linkages, which may now be approaching the end of their design life. During the test drive, pay particular attention to the rear braking system, as the recurring advisories for pitted and scored discs, combined with thin inner pads, suggest potential issues with caliper slide pins or uneven pad pressure. Listen for any grinding noises under light braking and check for a pulsating brake pedal, which would indicate warped or heavily scored discs. Furthermore, the 2025 failure involving the tyre pressure monitoring system and the restraint system warning lamp necessitates a thorough diagnostic scan. Ensure that all dashboard warning lights illuminate and extinguish correctly upon ignition, as any lingering faults in these systems could indicate deeper electrical or sensor-related complications. The repeated advisories for tyre wear on the inner edges, noted in both 2024 and 2025, warrant a professional four-wheel alignment check. Uneven wear patterns often point to misaligned suspension geometry or worn control arm bushings, which can lead to premature tyre replacement and compromised handling stability. When driving, observe the steering for any pulling to either side or vibration at motorway speeds, as these symptoms can confirm underlying suspension geometry issues. Inspect the condition of the tyres for consistent tread depth across the entire width of the contact patch, as the history of inner-edge wear indicates that the current suspension setup may be placing undue stress on the inner shoulders of the tyres.
