2018 Audi Q5 2.0L Petrol · B28 THH

A consistent pattern of brake and tyre-related advisories across multiple test cycles defines the mechanical profile of this 2019 Audi A3, with the most recent examination on 16 October 2025 returning a clean pass with no defects recorded, offering some reassurance about its current roadworthiness. However, the underlying record reveals recurring wear issues that a prospective buyer should not overlook. The 2023 test cycle produced identical advisories on both a pass and fail result, noting worn tyre edges across all four corners, pitted and scored front and rear brake discs, and an offside rear tyre exhibiting perishing. The 2022 test had already flagged rear brake disc wear at the same advisory threshold, indicating that brake disc degradation has been a persistent observation over several years. Although none of these items escalated to failure-level defects, the repetition suggests these consumables have been on a slow but steady decline and may now be approaching a service requirement. With 48,851 miles accumulated over approximately seven years, this A3 averages around 6,979 miles per year, which is broadly consistent with typical private use for a vehicle of its age. There are no significant gaps in the testing record that would suggest extended periods off the road, and the mileage progression between tests appears steady rather than erratic. This moderate usage profile is mechanically favourable in some respects, as it implies that major drivetrain components such as the engine, transmission, and clutch have not been subjected to excessive wear. Conversely, lower annual mileage can occasionally mask issues related to prolonged standing, such as dried rubber seals or corroded brake components, though the recurring brake disc pitting suggests the vehicle has seen regular enough use to keep the braking system active. Given the repeated advisories on the brake discs, a test drive should include firm brake applications from higher speeds to check for any vibration through the pedal or steering wheel, which would indicate disc runout or uneven wear beyond the previously noted surface scoring. Listen for any grinding or rubbing noises that could suggest pads are now contacting heavily worn discs, and inspect the discs visually for a pronounced lip on the outer edge, which would confirm they are nearing minimum thickness. The advisory regarding the inability to inspect rigid brake pipes due to undertray covers is particularly important for an Audi A3 of this age, as corrosion on brake lines is a known concern on MQB-platform vehicles, especially in areas with winter road salt. Before purchase, the undertray covers should be removed to allow a thorough inspection of all rigid and flexible brake pipes for surface rust, flaking, or active corrosion, paying particular attention to unions and flex line junctions near the wheel arches and subframe mounting points. The tyre wear pattern flagged as edge wear on all four tyres is worth investigating further, as uneven or rapid edge wear can point to suspension geometry issues such as worn wishbone bushes, top mounts, or drop links rather than simple inflation or alignment problems. On a test drive, listen for clonking noises from the front suspension over speed bumps and uneven surfaces, and feel for any vagueness or wandering in the steering, particularly during lane changes at motorway speeds. A four-wheel alignment check is advisable regardless, since the previous pattern suggests alignment may have been outside specification at some point. Finally, inspect the offside rear tyre sidewall closely for any signs of cracking or bulging, as perishing rubber at this age may now require replacement even if not flagged at the latest test, and confirm that all four tyres are of matching brand, size, and tread depth to avoid drivability issues on this front-driven Audi platform.
