2006 Audi A6 3.0L Diesel · CU56 XCT

The 2006 Audi A6 presents as roadworthy with a stable maintenance trend. The most recent test on 17 October 2024 at 142,619 miles passed with no defects recorded, and the prior clean pass on 29 September 2023 at 140,616 miles confirms the vehicle has cleared successive annual examinations without outstanding advisories. Mileage accumulation sits at a typical 7,131 miles per year for a 20-year-old car. The records show 132,262 miles in October 2021, rising to 136,695 by October 2022, then 140,612 at the failed test on 27 September 2023, and 142,619 by the October 2024 pass. The two-day gap between the 27 September 2023 failure and 29 September 2023 pass at near-identical mileage suggests a rectification retest, though the DVSA entry logs no defects for either, leaving the original fault undocumented. Annual use of roughly 4,000 miles since 2021 indicates light, steady running. A buyer should still commission an independent inspection of structural integrity and corrosion on sills, subframes, and suspension mounting points, as an 18-year-old Audi of this era is prone to hidden rust despite clean MOT slips. The tester recorded no advisories on brake discs, calipers, or suspension bushes across the five tests, yet worn components can escape detection between annual examinations. Given the sparse, defect-free history, previous owners appear to have maintained basic statutory compliance. The undocumented 2023 failure warrants a request for the original refusal certificate to confirm what was corrected before the retest pass.
