2006 Audi A4 2.0L Petrol · DN55 LZR

A front‑axle wear story dominates this 2006 Audi A4: the 2024 MOT recorded three major defects – a split near‑side CV boot and two ball‑joint dust‑cover failures that no longer protected against dirt ingress – and the 2023 test flagged a front brake disc that was worn, pitted and scored, plus corrosion on the rear suspension arms. The fact that the vehicle cleared the next two annual tests (2025 and 2026) with no defects suggests those items have been repaired, but the recent history highlights the front drivetrain and suspension as the areas that have required attention. At 121,886 mi the car averages roughly 6,100 mi per year, a mileage rate that sits comfortably within normal usage for a twenty‑year‑old saloon. MOTs have been recorded annually without any multi‑year gaps, indicating the vehicle has been kept on the road and subjected to regular testing. This steady accumulation points to gradual wear rather than a period of high‑intensity use, meaning consumables such as brake pads, tyre tread and suspension bushings are likely to be at a mid‑life stage rather than approaching the end of their design life. When you inspect the car, focus first on the repaired front CV joint and ball‑joint dust‑covers: look for any signs of fresh cracking, grease leakage or dirt ingress around the boot and the joint housings, and listen for a clicking or clunking noise when the steering wheel is turned at low speed. Examine the front brake discs for surface scoring, uneven wear or excessive run‑out, and test for any pulsation in the pedal under firm braking, which would indicate that the discs have not been resurfaced to a uniform thickness. The rear suspension arms should be inspected for surface rust that could have progressed beyond cosmetic corrosion; check for any looseness or play in the arm bushings and listen for a metallic knock over bumps, which would reveal lingering weakness from the previously noted corrosion. Finally, a short road‑test should verify that the steering remains straight and free of pull, that the suspension settles smoothly without excessive bounce, and that the brakes deliver firm, consistent feedback without vibration. Confirm that there are no unusual noises from the front drivetrain under acceleration or deceleration, and that the vehicle tracks evenly through a series of gentle corners. These checks will reveal whether the earlier major defects have been fully remedied and whether any residual wear remains that could require imminent attention.
