2007 Audi A4 3.0L Diesel · KV07 KZS

A recurring theme of deteriorating CV boots and worn suspension dust‑covers dominates the MOT history, signalling progressive exposure of drivetrain and suspension components to dirt and moisture. The latest test on 9 July 2026 recorded a clean pass with no defects, but the pattern of advisories – especially the repeatedly noted severe deterioration of the off‑side front outer drive‑shaft CV boot, the off‑side rear drive‑shaft boot, and the front lower suspension‑arm ball‑joint dust‑covers – shows that the underlying issues have not been fully resolved over several years. At 206 484 mi the car averages roughly 10 900 mi per annum, a mileage rate that sits squarely within normal usage for a 19‑year‑old executive saloon. The MOT log shows no long gaps in testing, but the dual entry on 17 October 2022 (a failure followed by a pass on the same day) indicates that at least one defect was remedied promptly enough to satisfy the examiner. The mileage figure, combined with the documented wear on CV boots, suspension dust‑covers and tyre tread, suggests that consumable wear items are approaching the end of their typical service life and will likely require attention soon. Prospective buyers should inspect the constant‑velocity (CV) boots on both the front inner and outer drive‑shaft joints for cracks, splits or grease leakage; any ingress of dirt can accelerate joint wear and produce a characteristic whine or vibration under acceleration. The central rear prop‑shaft bearing was flagged for slight play in 2023 and again in 2025, so a hands‑on check for any clunk or judder when applying throttle or decelerating, especially at low speeds, is essential. Verify that the front lower oil leak noted in 2023 and 2025 is limited to a minor seepage – look for oil spots under the engine bay and confirm that the leak does not affect the surrounding hoses or the clutch housing. The suspension dust‑covers on both front lower arms have been recorded as severely deteriorated on several occasions, which can allow water and debris to corrode the ball‑joint bearings. During a test drive, feel for any looseness or knocking when the steering wheel is turned over bumps, and listen for metallic clunks that may indicate worn ball‑joint internals. The rear axle corrosion advisory from 2023 warrants a visual inspection of the rear subframe and axle housings for rust flaking or pitting. Finally, the off‑side rear tyre failed on 7 October 2023 for tread below 1.6 mm; ensure that all tyres are uniformly worn, have adequate tread depth, and are free from side‑wall damage before committing to purchase.
