2018 Audi A5 2.0L Diesel · DC18 CSF

The 2018 AUDI A5 presents a pattern of recurring tyre wear and brake system degradation that spans three separate failing assessments between mid-2023 and late 2025. Three distinct MOT events recorded adverse findings for the same tyre positions—nearside front, offside front, and offside rear—all marked as worn close to legal limits within the 5.2.3 (e) advisory category. The December 2025 failure added a critical nearside front tyre tread depth breach below the 1.6mm requirement while repeating the previous year's tyre and brake pad warnings, whereas the March 2023 failure was classified as dangerous due to the same severe front tyre wear and rapidly thinning rear inner brake pads approaching the 1.1.13 (a)(ii) threshold. Despite a clean pass in December 2025, these repeated failures indicate unresolved mechanical issues rather than improved condition. With 48,750 miles recorded on an eight-year-old vehicle, the average annual accumulation of approximately 6,094 miles aligns with expected depreciation for its age, yet the absence of MOT registrations between the March 2023 failure and the December 2025 pass suggests extended intervals without official roadworthiness verification. This testing gap raises questions about how the persistent tyre wear and brake pad deterioration documented in earlier records continued unchallenged for more than eighteen months, potentially allowing cumulative damage to progress further. The mileage figure itself does not contradict the observed wear patterns but underscores a usage profile that may have involved regular braking and cornering loads sufficient to accelerate tyre and brake component consumption. The front tyre wear pattern identified across multiple assessments warrants close attention during any test drive, as consistently worn edges on both nearside and offside front wheels suggest either aggressive driving conditions or inadequate rotation that prevents even tyre compound distribution. When examining the brake system, the proximity of inner rear brake pads to the replacement indicator combined with the reported nearside front tyre tread depth breach points to progressive brake pad material loss that could compromise stopping power if left unaddressed. The December 2025 failure specifically noted a nearside headlamp aim issue alongside the other problems, so verifying proper light alignment is essential not only for road visibility but also to ensure all lighting circuits function correctly under load. For a prospective buyer, the front suspension bushings and subframe mounts deserve particular scrutiny given the recurring tyre wear on the nearside and offside front axles, as flexing or broken bushings can cause uneven wheel contact patch development and contribute to premature tyre flattening. Inspect the brake fluid reservoir and hoses for signs of leakage or discoloration, particularly around the inner rear caliper area where the pads showed thinning in prior records. Additionally, confirm the headlamp aim is centred on all four lamps and that the rear brake calipers move freely through their full range without binding, as restricted operation would exacerbate the existing brake pad wear trends. If possible, conduct a short test drive at moderate speed over varied surfaces to assess how the tyres respond to cornering forces and whether the braking response remains consistent throughout the journey.
