2018 Audi A8 3.0L Diesel · ND68 AAE

The current roadworthiness status is uncertain because the latest test on 5 February 2026 at 74,718 miles produced a failure with no defects recorded. Earlier entries show a stable, clean trajectory: the 8 December 2022 pass at 33,561 miles, the 20 October 2023 pass at 36,557 miles, and a peculiar same-day fail then pass on 5 February 2025 at 49,598 and 49,599 miles respectively, all with zero advisories. This repeated failure without logged defects points to documentation or procedural irregularities rather than worsening mechanical condition. The mileage progression reveals light early use then a pronounced surge. From 33,561 miles in December 2022 to 36,557 miles by October 2023 the car added only 2,996 miles in ten months. The gap to February 2025 brought the odometer to 49,598 miles, a 13,041-mile increase over sixteen months. Then within the single year to February 2026 the A8 covered 25,120 miles, lifting annualised use to about 25,000. That late heavy accumulation contrasts with the gentle initial pace and implies elevated load on drivetrain and consumables. No tester ever flagged suspension bushes, coil springs, binding calipers, brake discs, corrosion, exhaust emissions or structural integrity across the record. Despite the absent advisories, the eight-year age and the steep final-year mileage climb necessitate hands-on checks. A buyer must inspect underneath for rust, scrutinise suspension arms for worn bushes, and verify brake disc thickness and caliper freedom. The unexplained failures demand that the seller confirm the exact reasons with DVSA paperwork. Until a valid pass is secured, the A8 cannot be deemed roadworthy for retail.
