2014 Audi A8 3.0L Diesel · MM14 HYX

A recent engine‑management fault flagged by the MOT in July 2022, together with a brake‑pad wear‑indicator failure in 2018, constitute the only substantive mechanical blemishes on an otherwise clean record; the car subsequently passed its next test on 13 July 2022 and has recorded no further failures. Apart from a minor windscreen chip noted in 2019, every other annual test since 2017 has been passed without defects, indicating that the vehicle has not exhibited recurring structural or safety‑critical issues. At 134,567 miles the odometer reflects an average of roughly 11‑12 thousand miles per year, which sits squarely within normal usage for a 2014 model. The MOT history shows no gaps in testing, suggesting the mileage has been accumulated steadily rather than in large, undocumented bursts. This level of wear implies that standard consumables—such as suspension bushings, drive‑belt, and timing‑chain components—are likely approaching the latter half of their service lives and should be inspected for typical wear patterns. The engine‑management light (MIL) failure recorded in 2022 indicates a malfunction that prevented the system from operating correctly; a prospective buyer should have the ECU scanned for stored fault codes, verify that the check‑engine light is extinguished, and listen for any loss of power, rough idle, or abnormal exhaust emissions during a road test. Confirm that the vehicle runs smoothly at idle and under load, and that there are no warning lights on the dashboard, as unresolved MIL issues can affect fuel efficiency and emissions compliance. The 2018 brake‑pad wear‑indicator failure points to pads that were at or below the minimum thickness at that time; although the car passed the subsequent test, it is prudent to measure current pad thickness, inspect the discs for scoring or glazing, and assess pedal feel for any judder or sponginess. During a drive, listen for squeal or grinding on braking, note any pull to one side, and feel for vibration through the steering wheel, all of which would signal that the pads or related hardware may need replacement or further attention.
