2024 Audi A6 S Line 40 Tfsi Mhev S-A 2.0L Petrol · H23 KAB

With three consecutive clean MOT passes on record and no advisories whatsoever, this 2024 Audi A6 S Line 40 TFSI MHEV presents a roadworthiness profile free of any documented defects at the time of its most recent test on 3 July 2025. The vehicle has been examined annually since its first test in July 2022, passing cleanly each time without a single advisory or failure point. This unbroken clean record is particularly noteworthy given the electronic sophistication and mild-hybrid architecture of the A6, where emissions systems, AdBlue dosing, 12V lithium-ion battery integrity, and the MHEV 48V belt-driven starter-generator can all generate advisories on less carefully maintained examples. The absence of any recorded items suggests the vehicle has, at minimum on the day of each test, met all statutory roadworthiness requirements across lamps, brakes, tyres, suspension, exhaust, and structural integrity without any marginal or borderline observations. Against a vehicle that is roughly two years old, the recorded mileage of 70,112 miles equates to an annual accumulation of approximately 35,056 miles, which is very high for a premium executive saloon of this age. For context, the average UK driver covers around 7,000 to 9,000 miles annually, meaning this A6 has been used at roughly four times the typical rate. Such intensive use is most often associated with motorway commuting, fleet or company car duty, or long-distance business travel. Mechanically, this usage profile places accelerated demand on consumables and wear items: the DSG automatic gearbox oil and mechatronic unit, dual-mass flywheel if equipped, front and rear brake discs and pads, coil spring fatigue, suspension bushes, drop links, and the 48V mild-hybrid system's battery and DC-DC converter all experience higher cumulative stress. The fact that no advisories have been raised despite this mileage suggests these wear items were likely in serviceable condition at the last test, though they will be approaching or past their first replacement cycle. From a buyer inspection perspective, particular attention should be paid to the specific components that deteriorate under high-mileage, motorway-biased use. On a test drive, listen for any knocking or clonking from the front suspension over speed humps and uneven surfaces, which would indicate worn lower control arm bushes, anti-roll bar drop links, or top mount bearings. The DSG gearbox should shift smoothly through all gears without hesitation, flare, or a noticeable jolt on kickdown; any delay on initial acceleration or a shudder at low speed can point to mechatronic wear or clutch pack fatigue given the mileage involved. Brake pedal feel should be firm and progressive without excessive judder under braking, as warped front discs are common on heavily-driven examples even if not yet flagged as an advisory. The steering should remain precise and free of vibration at motorway speeds, and the 48V MHEV system should be observed for any warning messages on the instrument cluster, particularly relating to the mild-hybrid system or the 12V battery. Given the high annual mileage relative to age, a thorough pre-purchase inspection by an Audi specialist or independent German marque expert is strongly recommended, focusing on the DSG transmission oil condition and filter, brake disc wear and pad life remaining, suspension component condition with the vehicle on a ramp, and a diagnostic scan across all modules including the MHEV system, AdBlue tank and injector, and the electronic chassis systems. Tyre condition and evenness of wear across both axles should also be examined, as high-mileage motorway use accelerates shoulder wear. A service history verifying timely DSG oil changes, brake fluid renewal, and spark plug replacement at the correct intervals will be essential reassurance given how hard this particular example has been working.
