2006 Audi A4 2.0L Petrol · NK06 YCY

The most recent MOT history for this 2006 Audi A4 reveals a stable but erratic pattern, with no defects recorded across five tests over two years. The vehicle passed its most recent inspection on 26 March 2026 at 146,689 miles, yet it failed the preceding test just one day earlier at 146,685 miles—an unusual anomaly given no defects were logged. The previous failure occurred in April 2024 at 140,222 miles, also with no recorded issues, suggesting either a temporary administrative oversight or a brief period of non-compliance with MOT testing intervals. There is no evidence of recurring mechanical faults, but the abrupt retesting in March 2026 warrants scrutiny of whether the vehicle was driven between tests or if the failure was procedural rather than technical. The mileage progression indicates typical usage for its age, averaging around 7,300 miles annually, though this includes a notable gap between April 2024 and March 2026, where the odometer remained static at 140,222 miles for nearly a year. This suggests the vehicle may have been stored or used infrequently during that period, which could accelerate wear on components like suspension bushes, coil springs, and brake calipers due to prolonged immobility. The final 6,467 miles were covered in just over four months, a rate that may stress consumables like tyres and brake pads if maintenance was deferred. The lack of service records complicates this assessment further, as fluid changes and alignment checks are critical for vehicles of this age. Given the absence of defects in MOT history, priority should be given to inspecting high-wear areas that are not routinely tested. The suspension—particularly the rear bushes and coil springs—should be examined for cracking or excessive play, especially if the vehicle was stored for extended periods. Binding rear brakes, a common issue in older Audi models, should be checked for uneven pad wear or seized calipers, as this often goes unnoticed until failure. Tyre tread depth and lateral wear patterns are also critical, given the recent rapid mileage accumulation; uneven wear could indicate alignment or suspension issues. Structural corrosion, particularly around wheel arches, subframes, and exhaust mounts, should be thoroughly inspected, as this is a silent risk that MOT tests do not always detect. The absence of advisories in recent tests does not preclude these areas from requiring attention.
