2022 Audi A6 S LN BLK ED 40TDI Mhev Q SA 2.0L Heavy oil · ML22 OBH

The most recent DVSA MOT test for this Audi A6 S Line Black Edition 40 TDI MHEV Quattro was conducted on 2 April 2026, at which the vehicle was presented with 36,207 miles on the odometer and achieved a pass with no defects or advisories recorded. This follows the previous test on 18 March 2025, which also resulted in a pass but carried two advisories relating to the rear tyres being worn close to the legal limit and showing edge wear. Although the 2026 result is clean, the absence of recorded advisories on the latest test should not be interpreted as confirmation that the tyres have been replaced; it is plausible that new tyres were fitted prior to test, or that the condition has simply not deteriorated to advisory level. The maintenance trajectory appears broadly stable, with both tests passing cleanly, though the rear tyre edge wear noted previously suggests a pattern worth investigating before purchase. The vehicle is now just under five months into its current MOT certificate, providing a reasonable window of legal road use before the next test becomes due. With 36,207 miles recorded over approximately four years of age, this A6 is averaging around 9,000 miles per annum, which is broadly typical for a premium executive saloon of this type. This level of usage is moderate and suggests the vehicle has seen consistent, real-world driving rather than either severe high-mileage accumulation or prolonged periods of inactivity. For a Quattro diesel mild hybrid of this vintage, 9,000 miles annually represents relatively gentle service, meaning the drivetrain, turbocharger, diesel particulate filter, and AdBlue system are unlikely to have been stressed by excessive short journeys, which can otherwise cause DPF saturation, EGR valve contamination, and premature oil degradation. The annual mileage also implies that mechanical wear on major components such as the clutch, dual mass flywheel, and timing chain should be minimal, though the modest mileage means the buyer should pay closer attention to time-related degradation of fluids, rubber components, and ancillaries, as calendar age affects these irrespective of distance covered. Given the rear tyre edge wear advisories from the 2025 test, the buyer should carry out a careful inspection of the rear axle geometry and suspension condition. Edge wear, particularly on the inside or outside shoulder, is often indicative of incorrect camber or toe settings, worn suspension bushes, or failing coil springs, all of which are plausible failure points on a vehicle of this age and specification. On a test drive, listen for any clonking or knocking noises from the rear suspension over uneven surfaces, particularly speed humps and broken tarmac, and observe whether the vehicle tracks straight without pulling to either side. Inspect the rear tyres directly for uneven wear patterns, cracking, or perishing on the sidewalls, and verify the manufacturing date codes on the sidewalls to ensure they are recent replacements. The Quattro drivetrain should also be evaluated for any signs of fluid leaks from the rear differential, prop shaft, or transfer box, and any vibration through the steering wheel or under hard acceleration could indicate propshaft balancing issues or failing CV joints. Beyond the rear tyre advisories, several age-related checks are warranted on this vehicle given its modest annual mileage. The 12 volt battery should be tested for state of charge and load capacity, as modern vehicles with complex electrical systems and start stop functionality are particularly sensitive to battery degradation, and a four year old original battery may be approaching the end of its service life even with low mileage. Brake discs, particularly at the front, may exhibit corrosion or lipping from standing and light use, and the calipers should be checked for smooth operation and any signs of binding, which can manifest as uneven brake pad wear or pulling under braking. Fluid condition should be verified regardless of mileage; brake fluid is hygroscopic and should ideally be replaced every two to three years, while the diesel fuel system benefits from periodic inspection of the fuel filter and water separator. The DPF should be confirmed as healthy through a live diagnostic read, checking for stored fault codes, differential pressure values, and recent regeneration history, as low annual mileage can occasionally lead to incomplete regeneration cycles. Finally, verify the service book stamps and digital service history to confirm that oil and filter changes have been carried out at the manufacturer specified intervals, and inspect the bodywork and underside for any corrosion, particularly around the wheel arches, sills, and undertray mounting points, as Quattro vehicles with winter use may show early signs of surface corrosion.
