2006 Audi A4 2.0L Diesel · RN55 AEJ

This 2006 Audi A4 has demonstrated a stable roadworthiness trend over the past two years, with no defects recorded in any of the five most recent MOT tests. The most recent test on 2026-02-05—just five months ago—confirmed the vehicle passed without fail, though the immediate preceding test on 2026-02-03 failed for an unexplained reason, as no defects were logged. This anomaly suggests either a procedural oversight or a minor, non-recurring issue that did not recur in subsequent tests. The consistency of passing results indicates the vehicle has not experienced recurring mechanical failures, though the lack of advisories or defects in the record does not preclude hidden wear. The recorded mileage of 367,246 miles—equivalent to roughly 18,362 miles per year—is unusually high for a vehicle of this age, suggesting either intensive use or prolonged periods of neglect. The gap between the 2023 and 2024 tests spans 12,714 miles in a single year, while the interval between 2025 and 2026 covers 3,320 miles, indicating variable usage patterns. Such high annual mileage accelerates wear on suspension bushes, coil springs, brake calipers, and drivetrain components, particularly in a vehicle this old. The absence of advisories or defects in recent MOTs does not negate the need for thorough inspection of these high-wear areas. A prospective buyer should prioritise an in-person examination of the suspension system, including coil springs for fatigue cracks and bushes for excessive play or perishing. The brakes, particularly the rear calipers, warrant close scrutiny for binding or uneven wear, as the 2026 failure—despite no recorded defects—could hint at a latent issue. Structural corrosion should be checked along the sills, wheel arches, and subframe, as high mileage increases vulnerability to rust-related failures. Additionally, the exhaust system and emissions controls should be inspected for leaks or excessive corrosion, which often go unnoticed until they compromise structural integrity or performance. Given the vehicle’s age and mileage, a pre-purchase inspection by a qualified mechanic is strongly advised to identify any deferred maintenance or concealed damage.
