2014 Audi A6 2.0L Diesel · YA63 BYB

The vehicle presented a PASS at its most recent DVSA MOT examination on 18 December 2025, although two advisories were issued for the nearside and offside front tyres being worn close to the legal limit, with recorded tread depths of 2.5mm and 2.3mm respectively. Evaluating the broader MOT history reveals a generally stable maintenance trend, with the car passing every annual test since 2018 and only minor advisories recorded throughout. However, a closer inspection of the advisory pattern shows a recurring issue with front tyre wear, flagged in 2018, 2025, and arguably with the offside front in 2023, which suggests a persistent geometry or suspension-related cause that warrants investigation rather than being dismissed as routine consumption. The 2023 test additionally recorded advisories for both nearside and offside front lower suspension arm inner bushes, and while these were not deemed excessive at the time, they represent wear items that typically progress with continued mileage and should be monitored closely. With a recorded mileage of 115,878 miles across approximately twelve years, this A6 is accumulating around 9,656 miles annually, which sits comfortably within the typical range for a vehicle of this age and class. There are no significant gaps in the MOT record that would imply extended periods of standing, and the mileage progression between tests appears broadly consistent and incremental, indicating regular use rather than sporadic or inconsistent driving patterns. This level of usage is broadly favourable from a corrosion and battery health perspective, as it suggests the mechanical systems have been kept active, fluids circulated, and moving parts regularly exercised, reducing the likelihood of seized calipers, dry rot in rubber components, or severe underfloor corrosion that can afflict low-mileage or stored vehicles. That said, 115,878 miles is still a substantial figure for any car, and wear-related components such as suspension bushes, anti-roll bar links, engine mounts, and timing chain components on the higher-output Audi engines should already have been attended to or be approaching the upper end of their service life. For a prospective buyer, the recurring front tyre wear advisory is the single most important issue to investigate prior to purchase. Uneven or rapid front tyre wear on an Audi A6 of this generation is frequently attributable to misaligned camber or toe settings, worn suspension components such as control arm bushes, ball joints, or top mounts, or even a tired steering rack. On a test drive, listen for clonking noises from the front suspension over speed humps and uneven road surfaces, pay attention to any wandering or lack of straight-line stability, and check for uneven inner or outer shoulder wear on any tyres currently fitted. The front lower suspension arm bushes flagged in early 2023 should be physically inspected by placing the vehicle on a ramp or using a pry bar to assess for play, as bushes that were marginal three years and approximately 29,000 miles ago are highly likely to now require replacement. Given the mileage, it is also prudent to budget for replacement of the timing belt and water pump if this work has not been recently documented in the service history, along with the renewal of age-sensitive fluids including brake fluid, coolant, and the automatic transmission fluid if so equipped. Beyond the specific advisories, a thorough physical inspection is essential. Examine the front brake discs for any prominent lip or corrosion build-up around the rim, as discs on a car of this age often require skimming or replacement even where pad wear is acceptable. Check the rear calipers for any signs of binding, which is common on vehicles that do significant urban mileage, and verify that the handbrake holds firmly on an incline. Inspect all tyres, including those on the rear, for sidewall cracking or perishing consistent with their age, as rubber degrades regardless of tread depth. Lift the bonnet and check the coolant and brake fluid reservoirs for correct levels and any signs of discolouration, and confirm that the 12V battery is recent or has been tested, as batteries on vehicles of this age typically require replacement every four to six years. Finally, examine the underbody and wheel arch liners for any corrosion, particularly around suspension mounting points and the exhaust downpipes, and review the full service history to verify that the cam belt, oil changes, and major servicing intervals have been completed in accordance with the manufacturer's schedule for this particular engine variant.
