2014 Audi A8 3.0L Diesel · RJ14 JBO

The most recent DVSA examination on 7 August 2026 returned a Pass, but it is accompanied by a cluster of advisories that warrant careful attention from any prospective purchaser. An oil leak was noted, though it was not deemed excessive at the time of test; this should be monitored closely as even minor seepages from the sump, valve cover gaskets, or turbo plumbing on the A8's 4.2-litre powertrain can develop into more significant repairs if neglected. Of greater mechanical concern are the dual tyre advisories: both front tyres are exhibiting cracking or perishing of the sidewall rubber, and both rear tyres are worn close to the legal limit with evidence of uneven wear on the inner or outer edges. The pattern recorded in the 2025 test is equally revealing, where four separate advisories were raised against the front suspension arm pins and bushes, indicating wear across the entire front axle assembly at that time. Taken together, the trend over the past three tests shows a vehicle that is passing but with a progressively accumulating list of wear-related advisories, particularly around the front suspension geometry and consumable items such as tyres, rather than any improvement in condition. The recorded mileage of 116,611 miles over approximately twelve years equates to an annual average of around 9,700 miles, which is broadly typical for a luxury saloon of this age and is neither unusually low nor excessively high. The MOT record is reasonably consistent year on year, with no significant gaps in testing that would suggest long periods of standing, which is reassuring given the known susceptibility of air-suspended vehicles to component seizure and corrosion when left unused. The mileage progression does not indicate any rapid accumulation that would point to high-mileage motorway use, but it is sufficient that the major mechanical assemblies, including the engine, automatic transmission, quattro drivetrain, and braking system, will have experienced meaningful real-world wear commensurate with the recorded odometer reading. Given the advisories raised against the front suspension arm pins and bushes in 2025, a prospective buyer should carry out a thorough road test specifically listening for any clonks, knocks, or knocking noises transmitted through the cabin when traversing speed humps, potholes, or uneven road surfaces, as these are classic symptoms of worn suspension bushes that have progressed beyond the advisory threshold. On inspection, the front suspension should be checked for excessive play by hand, and particular attention should be paid to the front tyres for any uneven shoulder wear, which would suggest that the geometry has shifted due to bushing deterioration. The rear tyres being worn close to the legal limit and showing edge wear, combined with front tyre perishing, indicates that a full set of replacement tyres is imminent and this cost should be factored into any purchase negotiation. It is also worth inspecting the inner sidewalls of the front tyres closely, as sidewall cracking on a 2014-manufactured tyre is a classic sign of age-related rubber degradation and is a particular concern for a vehicle that may have covered motorway miles where high-speed cornering loads the sidewall structure. Beyond the recorded advisories, the engine management light being inoperative or indicating a malfunction at the 2025 failure is a noteworthy data point that warrants verification; the vehicle should be scanned with a diagnostic tool capable of reading VAG group fault codes to confirm that all emissions-related and engine management systems are currently functioning correctly, and that no permanent or historic fault codes remain stored. The oil leak noted at the most recent test should be traced to its source on a physical inspection, with checks made at the sump plug, oil filter housing, and cam chain covers, and the level and condition of the oil on the dipstick examined for any signs of discolouration or coolant contamination. For a 2014 Audi A8 of this mileage, irrespective of the MOT record, it is sensible to verify the service history thoroughly, confirming that the cambelt or timing chain service intervals have been observed, that the automatic gearbox fluid and filter have been changed at the recommended intervals, and that the coolant and brake fluid have been refreshed according to calendar rather than purely mileage-based schedules. The 12-volt battery should be load-tested given the vehicle's known sensitivity to voltage drop, and the air suspension compressor, valve block, and air struts themselves should be exercised to confirm quiet, level operation without any sagging at rest, as these are notoriously expensive components on this platform and their failure may not be captured within a standard MOT inspection.
