2018 Audi A6 2.0L Diesel · LE15 GHT

The defining mechanical note in this 2018 Audi A6's history is the pronounced inner-edge tyre wear across all four corners flagged at the most recent test on 2026-05-06, which warrants close scrutiny before purchase. Aside from this advisory and a minor nearside wiper defect, the vehicle carried a clean pass, continuing a generally stable roadworthiness trend over the documented testing period. The earlier 2025 test cycle did include a failure for a split constant velocity boot on the offside front outer drive shaft joint, though the vehicle subsequently passed the same day after rectification, and the 2023 and 2024 tests recorded no advisories at all. The absence of any structural corrosion advisories, brake pipe concerns, or suspension component flags is a positive indicator for a vehicle of this age, but the tyre wear pattern points to a specific mechanical or geometry issue that must be addressed. With 63,396 miles recorded over approximately eight years, the A6 has covered around 7,924 miles annually, which sits squarely within the typical range for a premium saloon of this vintage and indicates consistent if modest usage. There are no unusual gaps in the testing record or evidence of long periods off the road, so mechanical components such as the drivetrain, braking system, and suspension have been worked regularly rather than suffering the effects of prolonged standing. This steady accumulation rate suggests that major wear items should be at a predictable stage of their service life, with consumables like brake pads, discs, and tyres representing the primary expenditure rather than any deeper component failures. The advisory for tyre wear close to the legal limit on the inner edges of all four wheels is the single most important item to investigate on this vehicle. Inner-edge wear of this nature is commonly associated with incorrect wheel alignment, particularly excess negative camber or possibly worn suspension bushes and control arm joints that allow geometry to drift out of specification. On a test drive, listen for any clonking or rattling from the front suspension over uneven surfaces, particularly through speed bumps and potholes, and pay attention to any vagueness in steering response, tramlining at motorway speeds, or uneven steering pull under braking. Given the cost of replacing a full set of premium tyres on an A6 and the labour involved in diagnosing and correcting suspension geometry, a four-wheel alignment check followed by a close inspection of the front suspension arms, anti-roll bar links, and rear trailing arms should be prioritised during any pre-purchase inspection. The historic drive shaft boot split is also worth a brief physical check, even though it was rectified. Inspect the offside front inner and outer CV boots for any signs of fresh grease contamination or cracking in the rubber, as CV joints that have ingested contamination can fail prematurely. Beyond the recorded items, an A6 of this age and mileage should be inspected for oil seepage from the engine and turbo plumbing, coolant leaks from the water pump and thermostat housing, and any early signs of corrosion around the wheel arches, sills, and subframe mounting points. A thorough diagnostic scan for any stored fault codes, particularly relating to the timing chain stretch sensors and turbocharger actuator, would further strengthen confidence in the long-term mechanical condition of this vehicle.
