2020 Audi Q3 Sport 35 Tfsi Mhev S-A 1.5L Petrol · RO20 FSN

A pattern of progressive wear to the rear braking components and front tyres defines the mechanical trajectory of this 2020 Audi Q3, with the most recent test on 8 August 2026 demonstrating this trend clearly. That test initially resulted in a failure, though the reasons for the failure are not detailed beyond the advisories listed, before a pass was recorded the same day. The advisories on that occasion noted nearside rear brake disc wear, nearside rear brake pads wearing thin, both rear tyres close to the legal limit or worn on edge, offside front tyre wear, and offside rear brake disc wear. Two years earlier, the 2024 test had already flagged both front tyres as worn close to the limit and both front shock absorbers as showing light oil misting, suggesting the front tyres have been a recurring concern while the rear braking wear is a more recent development. The shock absorber misting was repeated on the 2025 test, indicating it has neither worsened nor resolved, while the rear brake wear only emerged at the 2026 examination. With 53,633 miles recorded over roughly six years, this Q3 has covered approximately 8,939 miles annually, placing it squarely within typical usage parameters for its age. The MOT record shows tests at 2023, 2024, 2025, and 2026 with no significant gaps in roadworthiness certification, confirming continuous use rather than extended periods off the road. This steady accumulation rate suggests normal wear progression on consumable items such as brake discs, pads, and tyres, and provides a reliable baseline for assessing remaining component life. The mid-range mileage also means the vehicle has not been excessively worked, reducing the likelihood of major drivetrain fatigue on the 1.5-litre mild-hybrid petrol powertrain and its associated automatic transmission. For a prospective buyer, the immediate priority is a thorough physical inspection of the rear braking system. The nearside rear brake disc and pads have been flagged as wearing, and the offside rear disc is also showing wear, so request a current pad and disc thickness measurement in millimetres. On a test drive, listen for any grinding or squealing from the rear axle during low-speed braking, and feel for pulsation through the brake pedal that would indicate disc lipping or runout. Inspect the rear brake pipes and flexi-hoses for corrosion or cracking, as these are common MOT failure points on vehicles of this age, and check that the rear caliper sliders are free-moving without binding. The front suspension also warrants close attention given two consecutive years of shock absorber oil misting on both sides. While light misting is not an immediate failure, it suggests the front damper seals are beginning to deteriorate, and you should check for any increase in the diameter of the damp area or wetness running down the damper body. On the road, drive over uneven surfaces and listen for clonking or knocking from the front end, which would indicate worn suspension bushes, top mounts, or anti-roll bar links. Additionally, inspect the front tyres carefully for uneven shoulder wear indicative of misalignment, examine all tyres including the spare for age-related sidewall deterioration, and verify that the tyre pressures and sizes match Audi specifications, as incorrect fitments frequently cause the edge-wear pattern flagged in the MOT record.
