2011 Audi A5 2.0L Petrol · LP11 XAT

A pattern of corrosion-related advisories and an increasingly burdened braking system define the mechanical character of this 2011 Audi A5, with the most recent test on 10 July 2026 returning a pass but only after flagging worn, pitted, and scored brake discs at both axles alongside brake pads that are reported to be wearing thin. Looking across the MOT sequence, the underlying trend is one of deterioration rather than stability: the 2025 cycle documented a corroded-away central exhaust clamp, an engine oil leak from the nearside front, multiple tyres worn to the legal limit, and a badly corroded rear subframe, while the 2024 testing period included a major failure for a clearly faulty oxygen sensor component of the emissions system. The recurrence of the same exhaust clamp issue across three consecutive tests indicates a long-standing concern that has not been rectified, and the persistent presence of subframe corrosion advisories suggests the structural underside is progressively degrading. Combined, these findings paint a picture of a vehicle whose roadworthiness is being maintained through pass-level tolerances but where multiple wear and corrosion issues remain active and unresolved. With 119,814 miles recorded across roughly fifteen years of service, the A5 is accumulating mileage at an annual rate close to 7,988 miles per year, which is broadly in line with typical usage for a car of its age and means the mechanical components have seen a steady, moderate workload rather than extreme high-mileage abuse. The MOT history shows no gaps in annual testing of any significant duration, suggesting the vehicle has remained in continuous road use throughout the period covered by the records. This consistent activity is generally favourable for keeping seals, fluids, and suspension components working, although it does mean that consumable items such as brake components, tyres, and exhaust mountings have all accumulated wear consistent with the mileage. For a prospective buyer, the priority items to inspect closely relate to the specific components already flagged in the MOT record. The front and rear brake discs and pads should be physically examined, as the most recent advisory specifies pitting and scoring that may not yet compromise outright braking performance but suggests the discs are nearing the end of their service life and could soon require replacement. On a test drive, listen for any scraping, grinding, or pulsation through the brake pedal under firm application, and check for the vehicle pulling to one side under braking, which could indicate a binding caliper or uneven pad wear. The underside of the vehicle warrants a thorough visual examination on a ramp, with particular attention to the rear subframe mounting points where the recorded advisories describe bad corrosion; any flaking, perforation, or structural softness in the surrounding metal would warrant serious professional inspection before purchase. The persistent exhaust clamp issue and the engine oil leak from the nearside front also merit direct attention. With the exhaust sleeve clamps reported as corroded away or snapped across multiple tests, the system should be checked for any blowing noises, rattles, or visible soot deposits around the joints, particularly under load when the engine is warm. The oil leak, while classed as not excessive, should be evaluated for its progression by inspecting the engine cover and surrounding components for fresh oil accumulation, and a check of the undertray and surrounding ancillaries is worthwhile to ensure the leak has not migrated onto hot exhaust components or electrical items. The 2024 major failure for a faulty oxygen sensor should prompt verification that the engine management light and EPC warning are not currently illuminated and that the emissions behaviour is smooth, without hesitation, misfire, or rough idle during the test drive, as the previous fault relating to the oxygen sensor and EPC light could resurface if the underlying cause was not comprehensively addressed.
