2014 Audi A6 3.0L Diesel · BD64 AEK

The 2014 Audi A6 has demonstrated a consistent roadworthiness record over the past three MOT cycles, with the most recent test on 2025-07-14 confirming no defects at 141,986 miles . The absence of advisories or failures in the last two tests suggests the vehicle has undergone regular, if not rigorous, maintenance, though the duplicate 2024-07-23 entry —where it was both passed and failed at the same mileage—appears anomalous and may indicate a clerical error rather than mechanical instability. The lack of recurring faults in the official record does not preclude hidden issues, particularly in high-mileage components like the suspension bushes, coil springs, or drivetrain joints , which often fail silently before becoming MOT-critical. The most concerning omission is the absence of any exhaust emissions or structural corrosion advisories, areas where Audi models of this age frequently develop leaks or body panel deterioration. The recorded mileage progression— 114,017 miles in July 2023 to 141,986 miles in July 2025 —implies an average of 11,832 miles per year , a rate typical for a well-used executive car. There are no suspicious gaps or spikes in mileage, though the 127,504-mile mark in July 2024 stands out due to the duplicate MOT entry, which could hint at either a test centre error or a brief period of non-use before retesting. The consistency of annual mileage suggests the vehicle has been driven regularly rather than left stationary, reducing the risk of fluid degradation or seized components. However, the lack of service history beyond MOTs means critical intervals for valve clearance adjustments, timing belt inspection, or differential fluid changes may have been overlooked. A prospective buyer should prioritise a detailed inspection of suspension components , particularly the rear coil springs and bushes , given the vehicle’s age and mileage. The front and rear brake systems warrant scrutiny for binding calipers, uneven disc wear, or master cylinder leaks , as these are common failure points in high-mileage Audis. Corrosion should be checked at wheel arches, sills, and underbody , especially around the exhaust system and subframe mounts , where water ingress can accelerate deterioration. The exhaust emissions system —though not failed in MOTs—should be probed for leaks or catalytic converter clogging, as these often develop between tests. Finally, the transmission and differential fluids should be inspected for discolouration or contamination, as their condition directly impacts longevity. The absence of MOT advisories does not guarantee these areas are sound, but it does indicate no immediate, overt failures.
