2005 Audi A6 2.7L Diesel · OY55 SJU

The defining mechanical story for this 2005 Audi is one of largely clean roadworthiness over a sustained testing window, interrupted by two isolated test events that highlight specific component vulnerabilities rather than systemic neglect. The most recent recorded activity in April 2019 saw the vehicle both pass and fail on the same date, with the pass carrying an advisory for rear brake disc wear and the fail citing dangerous tyre condition at the front, including ply exposure on the offside front tyre and an excessively deep nearside front tyre cut. Earlier, the only other recorded failure was in March 2017, limited to inoperative registration plate lamps, which is a minor compliance issue rather than a mechanical concern. Across the remaining tests between 2014 and 2018 the record is notably clean, with the 2015 test being the only other instance of advisories being issued, specifically for deteriorated front upper suspension arm rubber bushes. Taken together, the trend is one of generally stable roadworthiness with no recurrence of any flagged component, suggesting that the items identified in 2015 and 2019 were addressed rather than left to deteriorate further. With a recorded mileage of 117,321 miles spread across roughly twenty-one years of vehicle age, the annual accumulation rate works out at approximately 5,587 miles per year, which is substantially below the typical usage pattern for a car of this vintage. The MOT record covers the period from 2014 through 2019, with no tests recorded beyond April 2019, indicating either a change of keeper, a period of exemption from testing, or the vehicle being laid up or off the road in recent years. The mileage itself is modest for an Audi of this age, which generally means less wear on major drivetrain components, but the lack of recent testing activity combined with low annual mileage introduces the possibility that the vehicle has been standing for extended periods, where corrosion, dried rubber seals, and stagnant brake fluid can become relevant concerns even where recorded mileage is low. For a prospective buyer, the specific components flagged in the record deserve direct physical attention on inspection. The front upper suspension arm rubber bushes were noted as deteriorated in 2015, and although they were not deemed to be resulting in excessive movement at that point, rubber bushes of that age on a vehicle that may have stood for several years will typically have hardened, cracked, or perished further. On a test drive, listen for clonking or knocking noises from the front suspension over uneven surfaces, particularly over speed humps and potholes, and feel for vagueness or a delay in steering response that could indicate the bushes have finally worn to the point of allowing measurable movement. Additionally, inspect all suspension linkages, drop links, and ball joints by hand for free play, as components that have been stationary will often exhibit corrosion-induced stiffness before they fail. The brake-related advisory from 2019 and the rear disc condition warrant specific scrutiny given that brake components on a low-mileage, potentially stored vehicle can deteriorate through corrosion as readily as through wear. On inspection, check the rear brake discs for a pronounced lip at the outer edge, heavy surface rust, pitting, or scoring, as the advisory suggested the disc surface was already pitted at the last test. With the engine running and the vehicle stationary, confirm that the handbrake holds on an incline, that the brake pedal feels firm rather than spongy, and that there is no pulling to one side under braking, which could indicate a binding or seized caliper following a period of disuse. The dangerous tyre failures from April 2019 also serve as a reminder that the current wheels and tyres fitted to the car are not represented in the MOT history, so a close inspection of all four tyres for cuts, bulges, tread depth, and age-related sidewall cracking is essential before purchase, regardless of what the previous test record shows.
