2018 Audi A4 2.0L Diesel · BJ68 AAV

A recurring pattern of brake component degradation and tyre wear defines the mechanical profile of this Audi A4, suggesting that consumable maintenance is currently a primary focus. While the vehicle passed its most recent test on 19 February 2026, the record shows a trend of worsening brake condition, moving from simple advisories in 2022 to a dangerous failure regarding front brake pad thickness in early 2025, and most recently returning to advisories for worn and pitted rear brake discs and thinning pads. This cyclical issue with braking components, combined with a recent failure regarding headlamp aim, indicates that while the vehicle remains roadworthy, the braking system is approaching a stage of required replacement rather than mere monitoring. The vehicle has covered 115,919 miles over approximately eight years, representing an annual average of roughly 14,490 miles. This usage level is higher than the UK average for a vehicle of this age, which typically correlates with increased mechanical wear on high-stress components such as the suspension bushes, drivetrain, and braking assemblies. This higher mileage profile explains the frequent advisories regarding brake disc pitting and tyre wear, as the vehicle is clearly subject to regular, heavy road use rather than long periods of inactivity. Prospective buyers should account for the fact that components subject to friction and heat, such as the brake calipers and discs, will likely require more frequent intervention due to this consistent mileage accumulation. During a test drive, particular attention must be paid to the braking performance and the condition of the rear axle components. Given the recent advisories for pitted and scored rear brake discs alongside thinning pads, you should listen for any grinding noises during deceleration and feel for any pulsation or judder through the brake pedal, which can indicate uneven disc wear or warping. The advisory regarding a cut in the nearside rear tyre also necessitates a close physical inspection of all four tyres to ensure no structural damage exists beyond the surface level. Furthermore, the recent failure for incorrect headlamp aim suggests that any electrical or mounting issues with the lighting units should be verified to ensure the beam pattern is stable and does not flicker or shift during movement. Beyond the brakes and tyres, the history of worn discs suggests that the braking system has been under significant load. You should check for any signs of binding calipers or uneven pulling when applying the brakes, especially given the history of issues affecting both front and rear assemblies at different intervals. While the 2025 test showed no defects, the subsequent return of brake advisories in 2026 indicates that the wear rate is currently high. Ensure that the steering feels precise and that there are no knocks or knocks from the suspension when navigating uneven surfaces, as the high mileage and frequent tyre wear advisories can sometimes mask underlying issues with wheel bearings or suspension linkages.
