2019 Audi A6 S LN BLK ED 45 Tfsi Quat SA 2.0L Petrol · C4 MYG

The defining mechanical theme across this Audi A6's MOT history is a developing pattern of suspension wear that warrants close attention, even though the vehicle has never failed a test. The most recent examination on 25 November 2025 produced three advisories, all pointing to the same chassis area: both rear lower coil spring mountings were flagged as corroded though not seriously weakened, and the nearside front lower suspension arm pin or bush was again noted as worn, with a bent arm recorded. This nearside front lower arm advisory is actually the second consecutive year it has appeared, having first been noted in December 2024, which indicates a persistent issue that has not been rectified between tests. The earlier 2023 test only flagged front tyre wear, while the 2022 pass was completely clean, so the trajectory over four tests is one of progressively accumulating suspension and chassis advisories rather than a stable or improving record. None of these items have yet crossed the threshold into failure, but the clustering of rear spring corrosion and front arm wear in a single test suggests the undercarriage is beginning to demand more serious inspection. Annual mileage for this seven-year-old vehicle stands at roughly 7,893 miles per year, which is broadly typical for its age and not suggestive of either excessive motorway use or extended periods off the road. There are no significant gaps in testing history, with annual MOTs recorded from 2022 through 2025, indicating the car has been in continuous use and has not been laid up for any prolonged period that might raise separate concerns about seized brakes, perished fuel lines, or stale fluids. At 55,248 miles the engine, transmission, and quattro drivetrain are still well within their working life for a vehicle of this type, and the wear items appearing in the MOT record are consistent with what one would expect from a car that has been driven regularly rather than stored. The relatively even annual accumulation also means the brake discs, pads, and tyres will have been exercised under normal conditions rather than suffering the corrosion and flat-spotting issues that affect very low-mileage or stored vehicles. For a prospective buyer, the priority areas to focus on are the rear coil spring mountings and the nearside front lower suspension arm. The rear mountings were recorded as corroded but not seriously weakened in late 2025, and corrosion in this area tends to spread, so a physical inspection underneath the car is worthwhile, ideally with the vehicle raised, to check whether the corrosion has progressed to the spring seats themselves, the rear axle subframe, or adjacent brake pipe brackets. On the nearside front, the recorded bent arm combined with worn pin or bush movement is a known wear item on A6 models of this generation, and you should listen for clonking or knocking noises from the front suspension over speed humps, uneven road surfaces, and during full-lock manoeuvres at low speed. Any vagueness in the steering, wandering at speed, or uneven tyre wear across the front axle would reinforce the need for the arm and bush assembly to be replaced, as continued driving with a bent arm can accelerate inner shoulder wear on the front tyres and place uneven loading on the nearside driveshaft joint. A test drive should also pay close attention to brake feel, since the rear calipers and discs on a quattro vehicle of this age and mileage can begin to bind or judder, and a pulling sensation under braking or a pulsating pedal would warrant further investigation. Check that all four tyres are matching in brand, size, and tread depth, given the 2023 advisory that both front tyres were worn close to the legal limit and worn on the edge, which can indicate either geometry misalignment or stretched ageing rubber. Listen at idle for any timing chain rattle from the 45 TFSI engine, particularly on cold start, and confirm that the quattro system engages smoothly by accelerating through a wet or slippery patch to feel for any binding or shudder from the centre differential. Finally, request that the nearside front lower arm be inspected on a ramp before purchase, and obtain a quote for replacement alongside any necessary rear spring mounting repairs, as these are the items most likely to require attention within the next twelve months based on the recorded test history.
