2019 Audi A6 2.0L Diesel · XO10 CSO

The 2019 Audi A6 has demonstrated a stable roadworthiness trend over the past two years, with the most recent MOT test on 7 January 2026 confirming no defects at 70,662 miles. The absence of advisories or failures in the last two tests suggests the vehicle has not experienced recurring mechanical issues that would indicate neglect or impending failure. However, the near-consecutive failure and retest in January 2025—just two days apart—warries scrutiny, though no specific faults were recorded, which may imply a minor oversight rather than a systemic problem. Mileage progression reveals a consistent pattern of approximately 10,095 miles annually, which aligns with typical usage for a vehicle of this age. The gap between the May 2023 test at 39,603 miles and the October 2024 test at 60,319 miles indicates roughly 20,716 miles covered in 17 months, suggesting regular driving rather than prolonged inactivity. The lack of significant mileage spikes or prolonged periods of low usage further supports that the vehicle has been operated under normal conditions without extreme wear patterns. Given the clean MOT history, a buyer should prioritise an in-person inspection of high-wear components that often fall outside MOT scrutiny. The Audi’s suspension—particularly the rear coil springs and bushes—should be examined for uneven wear or corrosion, as these are common failure points in high-mileage vehicles. Brake systems, including caliper binding and disc thickness, warrant close attention, especially if the vehicle exhibits uneven braking or a pull to one side. Structural integrity, particularly around wheel arches and sills, should be checked for corrosion, as Audi models from this era can be prone to rust progression in wet climates. Finally, the exhaust system and catalytic converter should be inspected for leaks or damage, as these are frequently overlooked but critical for emissions compliance and structural safety.
