2011 Audi A5 1.8L Petrol · KX11 WKY

Chronic wear in the front brake, suspension, and steering assemblies is the defining mechanical theme of this 2011 Audi A5, with the most recent test on 24 October 2025 recording advisories for a worn nearside front upper suspension arm pin or bush and a worn rear brake disc. Both items passed the threshold for immediate failure but are flagged for ongoing monitoring, suggesting that the underlying consumables and chassis components are reaching the back end of their service interval. The broader MOT history supports this picture of progressive wear rather than any single catastrophic failure. On 23 October 2024 the vehicle failed its test on a major defect for excessive fluctuation in the front service brake, alongside advisories for worn front brake discs and steering rack free play noted again in October 2023. That steering rack advisory, now appearing at two consecutive tests, is a particular concern as it indicates a component that has not been rectified and may progressively degrade. A pair of dangerous tyre failures in October 2023 for torn inner rear tyres were the most serious recorded event, though these were rectified to allow a pass later that same day. With 165,336 miles recorded over roughly fifteen years, this A5 has averaged around 11,000 miles annually, which is broadly typical for its age and indicates consistent use rather than long periods of standing. There are no unusual gaps in the MOT testing history that would suggest extended lay-up, and the mileage accumulation appears steady year on year. At this odometer reading, expect meaningful wear across the entire drivetrain and chassis, particularly given the recurring advisories already evident. The combination of average annual mileage and chronic chassis advisories points to a vehicle that has been used regularly but is now entering the phase where suspension, steering, and braking components require closer attention and likely replacement. For a prospective buyer, the upper suspension arm bush flagged in the latest advisory is a priority inspection point. On a test drive, listen for knocking or clonking noises from the front suspension over speed humps, uneven road surfaces, and during sharp low-speed turns, which would indicate the bush has worn beyond acceptable movement. With the steering rack free play noted at two consecutive tests, pay close attention to any looseness, rattle, or inconsistent self-centring through the wheel, particularly when transitioning between left and right lock, and check for uneven or feathered tyre wear on the front pair as a secondary indicator of play in the rack or tie rods. The brake-related defects are equally important to verify in person, as the major failure for fluctuating front brake effort and the advisories for worn discs suggest the caliper guide pins, flexible hoses, or pads may be due for attention; during a road test, feel for any judder, pulling to one side under firm braking, or a soft or inconsistent pedal, and visually inspect the discs for a pronounced lip or scoring on the outer edge. Given the age and mileage, it is also prudent to inspect for oil leaks from the engine and front differential area, as these are common on higher-mileage Audi vehicles of this era and have not been recorded in the MOT history but would not necessarily be flagged at test. Check the underside of the engine and the front subframe mounting points for any corrosion, particularly around suspension pick-up points where rust can compromise structural integrity. The tyres should be examined for age-related cracking in the sidewalls regardless of tread depth, given the prior dangerous failures recorded on the rear inner tyres. Finally, verify that the recent brake and suspension advisories have been addressed or budget for their imminent replacement, as the pattern across the last three tests suggests these items are on a deteriorating trajectory rather than a stable plateau.
