2021 Audi S3 Tfsi Quattro S-A 2.0L Petrol · F5 AJU

The vehicle is currently roadworthy, though the maintenance trend indicates a recent lapse in preventative care. While the most recent test on 28 November 2025 at 37,514 miles resulted in a failure due to rear brake pads being below the 1.5mm threshold, the immediate re-test pass on the same day confirms the owner addressed the defect promptly. This suggests a reactive but functional approach to maintenance rather than a proactive schedule of replacing consumable components. The mileage pattern remains consistent with a five-year-old vehicle, averaging approximately 7,500 miles per annum. Between the November 2024 test at 24,670 miles and the November 2025 test at 37,514 miles, the car covered 12,844 miles. This represents a significant spike in usage compared to the overall annual average, which places a higher load on the Quattro drivetrain, braking system, and suspension components relative to lower-mileage examples. A buyer should physically inspect the braking system to ensure the replacement rear pads did not result in uneven wear on the brake discs. Given that the tester flagged thin pads, it is necessary to check for signs of heat scoring or glazing on the rotors which may have occurred while operating with such worn material. Additionally, examine the front suspension bushes and control arms for premature cracking, as the increase in mileage over the last year can accelerate the degradation of rubber components on a performance-oriented vehicle like the S3.
