2015 Audi A3 2.0L Diesel · S33 DAA

The most recent DVSA MOT, carried out on 16 February 2023, resulted in a Pass with two advisories concerning the near‑side rear brake pad being thin and the rear brake disc showing surface pitting. The preceding test, dated 23 February 2022, also passed with no recorded defects. The appearance of brake‑related advisories after a clean year suggests a modest decline in the wear condition of the rear braking system, while the overall maintenance record remains stable and the vehicle has otherwise met the statutory requirements. At eleven years old the Audi A3 has accumulated 113 061 miles, which averages just over 10 000 miles per annum. This is within the normal usage envelope for a compact executive model and does not indicate excessive short‑term mileage spikes or prolonged periods of inactivity. The mileage pattern points to regular, moderate use rather than high‑stress operation, meaning that major power‑train components such as the timing chain, gearbox and engine bearings are likely to have experienced typical wear rather than accelerated degradation. Prospective owners should give the rear braking assembly close attention. The thin near‑side rear pad will soon require replacement; a visual inspection should confirm pad thickness on both sides and check for uneven wear that could indicate a sticking caliper. The pitted rear disc, while not yet a safety‑critical fault, should be measured for run‑out and thickness; excessive scoring can lead to brake pulsation or reduced stopping efficiency, especially under hard braking. During a road test listen for any rear‑wheel squeal or low‑frequency shudder when applying the brakes, and feel for any pull to one side that might reveal a caliper that is beginning to bind. Planning a brake service – pad renewal on both rear wheels, disc resurfacing or replacement if the minimum thickness is approached, and a thorough caliper cleaning – is advisable within the next few thousand miles. Beyond the brakes, the car’s age warrants a comprehensive visual and tactile appraisal. Examine the tyre sidewalls for cracking, dry rot or uneven tread wear that could betray mis‑alignment or suspension degradation; tyre age alone (over ten years) can render rubber brittle regardless of tread depth. Inspect the suspension bushings, ball joints and shock absorbers for any signs of corrosion, leakage or excessive play, as prolonged exposure to moisture can accelerate wear. Verify the 12‑volt battery’s state of charge and cranking performance, particularly if the vehicle has spent periods standing idle, and consider a load test. Check that all fluid reservoirs – engine oil, coolant, brake fluid and gearbox oil – are topped up and that the brake fluid has been changed at least every two years, as hygroscopic fluid can deteriorate over time. Finally, review the service book for regular oil changes, timing‑belt or chain service intervals, and confirm that any recall work relevant to the 2015 A3 has been completed. These checks will help ensure that the vehicle remains mechanically sound and that any age‑related maintenance is addressed before purchase.
