2005 Audi A6 Allroad TDI Quattro Auto 2.5L Diesel · AJ05 WBV

The Audi A6 Allroad presents a current roadworthy status with a clean pass recorded on 24 June 2023 at 155,758 miles, yet the surrounding history shows a destabilising pattern of repeated failures immediately prior. In June 2023 the vehicle failed twice within three weeks, first on 04 June at 155,633 miles and again on 17 June at 155,704 miles, before the eventual pass seven days later. The MOT record logs no defects against either failure, which points to administrative or presentation issues at test rather than documented mechanical faults. The maintenance trend is therefore unstable around the latest test, with resolution achieved only after three attempts. Mileage accumulation is moderate for a 21-year-old vehicle, averaging roughly 7,400 miles per year against the 155,758 miles recorded. A notable gap exists between the 15 January 2022 pass at 148,483 miles and the 13 December 2021 fail at 148,114 miles, where only 369 miles separated the two entries. The climb from 148,483 miles in January 2022 to 155,633 miles by June 2023 shows around 7,150 miles covered in seventeen months, consistent with light use. The record is sparse and clean outside the June 2023 cluster, with no advisories or corrosion flags logged across any entry. A buyer should still commission an in-person inspection of suspension bushes, coil springs, and brake discs given the allroad air suspension and Quattro drivetrain at this mileage. The twin June 2023 failures with zero recorded defects suggest the vehicle may have been presented poorly or carried undocumented faults cleared before retest. Verify structural integrity underneath for corrosion and check the exhaust emissions system, as the TDI engine at 155,758 miles warrants scrutiny of turbo and DPF condition despite the clean MOT trail.
