2006 Audi A6 2.0L Diesel · YG06 ADU

The vehicle failed the MOT on 24 September 2021, recording critical defects such as inoperative parking brakes on both axles, a non‑functioning dipped headlamp, brake pads below the 1.5 mm limit, a faulty centre seat‑belt buckle, deteriorated front suspension ball‑joint dust covers, an oil leak, rear anti‑roll bar linkage play and extensive corrosion on the rear subframe, inner sills and suspension spring mountings. No further MOT entries exist up to 8 August 2026, so the maintenance trend is stagnant and the car remains unroadworthy in its present condition. Mileage data stops at 171,058 mi on the 2021 test, which averages roughly 8,500 mi per year for a 20‑year‑old Audi A6 – a typical figure for the segment. The four‑year‑plus gap without a new MOT means recent wear cannot be gauged and suggests the vehicle may have been stored or infrequently used. A buyer should physically check the parking brake actuation on both rear wheels, measure pad thickness and inspect front and rear discs for fouling, examine the front lower suspension ball‑joint dust cover and rear anti‑roll bar linkage for play, and assess the rear subframe and inner sills for corrosion. The oil leak source, suspension spring‑mount corrosion, the dipped headlamp operation and the centre seat‑belt buckle must also be verified before any purchase. The concentration of brake, suspension and structural faults indicates extensive remedial work is required. The absence of recent MOT data reinforces the need for a comprehensive pre‑purchase inspection to establish the true roadworthiness of the vehicle.
