2022 Audi A6 S Line 40 TDI Mhev Quat S-A 2.0L Diesel · GY22 YRF

The 2022 Audi A6 S Line 40 TDI MHEV quattro S-tronic presents an encouraging mechanical picture based on its DVSA history, with the most recent assessment on 27 August 2025 recording a clean pass and no advisories or defects noted. The only blemish in the file is a failure recorded just fifteen days earlier on 12 August 2025, but with no defects recorded against that test, this almost certainly reflects an administrative or technicality issue rather than a genuine mechanical concern, as DVSA records would typically itemise specific failure points if the vehicle had not met the required standard. The absence of any advisories across the recorded tests means there is no documented pattern of wear items creeping toward replacement, no flagged corrosion to suspension or braking components, and no recorded issues with emissions, lighting, or structural integrity that a buyer would need to factor in. For a four-year-old executive diesel, this clean sheet is a positive indicator of overall roadworthiness. With 40,145 miles recorded against an age of roughly four years, this vehicle is accumulating mileage at approximately 10,000 miles per year, which sits firmly within the typical usage band for a premium diesel saloon of this type. There are no unusual gaps in testing or sudden mileage jumps between recorded readings that would suggest prolonged off-road storage or inconsistent usage patterns. At this annual accumulation, the mechanical wear items that typically begin to demand attention on an A6 of this generation, including brake discs and pads, tyres, and the more expensive suspension components such as control arms and bushes, should be approaching but not necessarily requiring replacement. The mild-hybrid 40 TDI powertrain and quattro drivetrain are designed for sustained higher-mileage use, so this vehicle has not been worked particularly hard relative to its design parameters. Given the clean MOT record, a prospective buyer should focus their physical inspection on the components and systems most likely to show wear at this mileage on an A6 of this vintage, even though they have not yet been flagged by an MOT tester. On a test drive, listen carefully for any knocking or clonking from the front suspension over uneven surfaces, which could indicate worn lower control arm bushes, anti-roll bar drop links, or top mounts, all common wear points on the C8 platform. Pay particular attention to brake pedal feel, looking for any judder under moderate braking that would suggest disc warping, and check for uneven pad wear or any binding from the calipers. The S-tronic dual-clutch transmission should shift smoothly through all gears without any shunt or hesitation, and any vibration through the steering at speed could indicate prop shaft or front differential issues worth investigating on the quattro system. A thorough under-bonnet inspection should also include a check for any oil seepage from the engine and transmission, as well as a visual inspection of the condition of the coolant and brake fluid, since service items would have been due at intervals during this mileage. Inspect the underside of the vehicle for any signs of corrosion to the subframe, brake pipes, or fuel lines, as these are areas that can deteriorate on vehicles that have seen motorway use in winter conditions. The 19 or 20-inch S Line wheels are particularly vulnerable to kerbing damage, so a close look at the alloy edges and a check of the tyres for uneven inner shoulder wear, which would point to suspension geometry issues, would be worthwhile. Finally, confirm that the mild-hybrid system is functioning correctly, as a warning light on the dashboard relating to the 12-volt system or the belt-driven starter generator would warrant further investigation by a specialist before purchase.
