2006 Audi A4 2.0L Diesel · VO06 WUR

The 2006 Audi A4 presents a mixed maintenance picture. The most recent MOT, a pass recorded on 29 September 2022 at 139,307 miles, is now nearly four years old, meaning the vehicle has no valid roadworthiness certificate today. That final pass was preceded by a failure on the same day for headlamp aim and a non-working nearside stop lamp, both rectified within hours. A rear suspension arm pin or bush advisory appeared on both the pass and fail certificates from that September 2022 visit, indicating the tester noted wear but deemed it insufficient to fail the vehicle. The overall trend is neither clearly improving nor worsening, but the long gap since the last test leaves significant uncertainty about the car's current mechanical state. Mileage accumulation tells a story of very light recent use. The vehicle covered just 1,326 miles between the February 2021 test at 137,981 miles and the September 2022 test at 139,307 miles, a span of roughly nineteen months. Before that, the car averaged around 8,942 miles per year between January 2020 at 129,039 miles and February 2021 at 137,981 miles, which is more typical for a vehicle of this age. The sharp drop in annual mileage after early 2021 suggests the car may have spent extended periods stationary, a pattern that can cause its own problems including flat-spotted tyres, seized brake calipers, and deteriorated rubber components. The MOT history flags several areas demanding close physical inspection. The 2021 failure identified deteriorated track rod end ball joint dust covers on both front corners, slight play in the nearside track rod end, and a parking brake below minimum efficiency. Although the car passed in 2022, there is no evidence these steering components were replaced rather than simply re-tested after adjustment. A buyer should check for uneven tyre wear, knocking from the front end over rough surfaces, and the parking brake's holding gradient on a slope. The 2020 advisory for worn and pitted rear brake discs also warrants inspection, as does the rear suspension bush wear noted in 2022, which can progress to noticeable clunking or vague handling if left unattended. Corrosion risk is the silent concern with any twenty-year-old Audi A4, particularly around rear arches, sills, and subframes where moisture traps accelerate structural decay. The MOT records do not document any corrosion-related failures, but the absence of recent testing means any deterioration since September 2022 remains unrecorded. A thorough underside inspection with a torch and probe is essential before purchase, alongside a check of all suspension bushes, coil springs, and exhaust mounting points for perishing or cracking consistent with age rather than mileage alone.
