2021 Audi A3 Sport 30 Tfsi 1.0L Petrol · WN21 MBO

A front upper anti-roll bar linkage failure in 2024, paired with brake pad advisories at both axles on the most recent pass, defines the mechanical profile of this 2021 Audi A3. Across the recorded MOT history the vehicle has demonstrated consistent roadworthiness, passing four of the five recorded tests, with the single failure occurring on the same date as a pass where it was retested the same day and cleared aside from washer fluid and the anti-roll bar ball joint dust cover. The April 2026 pass with advisories on both front and rear brake pads suggests the braking system is approaching a service interval, although the wear rates appear proportionate for the mileage accrued. The overall trend shows the car has remained compliant on safety-critical items throughout its testing life, with no structural corrosion, exhaust, or tyre-related advisories escalating across consecutive tests, aside from a near-limit rear tyre and a nail-in-tyre advisory in 2025 that would warrant inspection of the repaired wheel for balance or sidewall integrity. With a recorded mileage of 47,716 miles across approximately five years of use, the vehicle is accumulating just under 9,500 miles annually, a rate broadly consistent with typical commuter and mixed-use patterns for its age. There are no significant testing gaps and the mileage progression between tests does not indicate periods of extended standing or unusually rapid accumulation, which means component wear from cold starts, corrosion from infrequent use, and accelerated drivetrain fatigue are not flagged concerns from the recorded history. The annual mileage suggests moderate use, where consumables such as brake pads, tyres, and suspension bushes will have experienced steady but not excessive wear. Given the front brake pad advisory issued in 2026, a buyer should anticipate replacement within the next few thousand miles, particularly if the vehicle is used predominantly in urban or stop-start conditions. The 2024 anti-roll bar linkage failure is the most mechanically significant item in the record and should be a focus area during any pre-purchase inspection. On a test drive, listen for clonking or rattling noises from the front suspension over speed humps, rough surfaces, and during direction changes, as a perished dust cover on a ball joint typically precedes play in the joint itself, which can manifest as imprecise steering response or a vague feeling through the wheel on turn-in. With 47,716 miles recorded, the original or replacement front linkage may have been fitted around the time of the 2024 test, so a physical inspection of the bushes and ball joints for splits, grease migration, or excessive free play is sensible. Similarly, the rear brake pad advisory from April 2026 should prompt a visual check of pad material thickness and disc condition, as worn rear pads on the A3 can occasionally be accompanied by sticking or binding calipers, producing a pulling sensation under braking or uneven pad wear across the axle. The 2025 advisories on the nearside rear tyre being close to the legal limit and worn on edge, together with a nail-in-tyre advisory on the offside rear, suggest the rear axle geometry or tyre pressures may have been a contributing factor. During a test drive, pay particular attention to straight-line stability, any steering pull to one side, and whether the rear end feels unsettled over undulating road surfaces, as edge wear can indicate misalignment following a kerb impact or prolonged under-inflation. The windscreen washer failure from 2024 was a trivial defect and bears no mechanical significance, though confirming washer operation and headlamp condition remains a simple but worthwhile check. Finally, given the car is now five years old with approaching 50,000 miles, a buyer should plan for replacement of tyres as a set, inspect the condition of all four brake discs for lipping or corrosion, and verify that the TPMS warning light behaves correctly on ignition, as this was flagged as illuminated on the dashboard during the 2024 tests.
