2008 Audi A6 2.0L Diesel · PL05 KEY

The 2008 Audi A6 achieved a PASS at its most recent DVSA examination on 11 July 2025, although the inspector recorded four advisories that warrant attention from any prospective buyer. Two advisories concern worn suspension arm pins or bushes at both front corners, a further advisory notes corrosion to the sills, and the fourth records slight play in the offside front track rod end ball joint. Reviewing the broader MOT history, the maintenance trend appears broadly stable but with recurring themes that suggest progressive wear typical of a vehicle of this age and mileage. Between 2020 and 2024, the car passed three consecutive tests with little or no advisory content, indicating a period of reasonable mechanical condition. However, the 2023 test introduced multiple advisories relating to front intercooler oil leakage, sill damage at suspension mounting points, and tyre wear, whilst the 2024 test featured a fail with dangerous tyre tread depths at three positions alongside failed position lamps, followed by an immediate pass with no advisories the day after repairs. The accumulation of suspension-related advisories in both 2022 and 2025, alongside the structural sill advisories in 2023 and sill corrosion advisory in 2025, suggests that wear is advancing gradually rather than being fully resolved between tests. With 161,776 miles recorded across approximately 18 years, the vehicle has accumulated around 8,988 miles annually, which is broadly typical for its age and indicates consistent rather than sporadic use. There are no extended standing periods evident from the MOT cadence, and the mileage progression between tests does not suggest any unusually rapid accumulation that would point to a hard-driven history. That said, at this combined age and mileage, a buyer should anticipate that major drivetrain service items such as timing belt replacement, automatic transmission fluid changes, and coolant system renewal will either have been completed or will be due shortly if service records cannot fully substantiate prior work. The average annual mileage figure also implies normal urban and mixed-use wear patterns, which on an Audi A6 of this generation commonly manifests as age-related deterioration of rubber, plastic, and electronic components rather than outright mechanical failure. Given the recurring advisories around front suspension components, a prospective buyer should pay particular attention to the feel and behaviour of the front end during a test drive. Listen for clonks or knocks over speed humps, uneven bumps, or when turning at low speed, as these commonly indicate worn lower control arm bushes or anti-roll bar drop links, both known wear points on this chassis. Uneven or feathered tyre wear across the front axle, particularly inner-edge wear, would corroborate the worn suspension geometry and the slight play recorded in the track rod end. The track rod end itself is a safety-critical steering joint; even slight play at advisory level can progress, so a specialist should assess the joint for excessive movement and check for perished or cracked rubber boots on the rack and pinion. The advisories relating to sill corrosion should be physically inspected, ideally on a ramp, to confirm that any corrosion is purely surface level rather than penetrating the structural sill sections, as the MOT history notes damage at suspension prescribed mounting areas on both sides which could compromise future test outcomes if left unaddressed. Beyond the items flagged by the DVSA examiner, a buyer should undertake several age- and mileage-appropriate physical checks before purchase. Inspect all tyres closely for both tread depth and, more importantly given the vehicle's age, for sidewall cracking, perishing, and any bulges, as rubber degrades with calendar age regardless of mileage. Examine the brake discs for lipping, corrosion pitting, or any binding caliper symptoms by checking for hot wheels after a short drive or uneven pad wear. Verify the 12V battery's state of health, as batteries beyond five to six years old often struggle in colder months, and request evidence of recent replacement if possible. Open the bonnet and look for any signs of fluid leaks around the coolant hoses, oil filter housing, and the front intercooler pipework noted in the 2023 advisory, as perished hoses are a common failure point on high-mileage Audi V6 engines. Finally, confirm the service book stamps and request evidence of major scheduled items, including cambelt and water pump replacement, brake fluid changes within the last two years, and differential or haldex servicing if applicable, as neglect of these time-sensitive items can lead to disproportionately costly repairs.
