2003 Audi A4 1.9L Diesel · KY03 AMX

The vehicle’s most recent MOT test on 2026-01-21 confirms it remains roadworthy, though the immediate preceding test on 2026-01-14—just seven days earlier—was a failure without recorded defects. This suggests either a minor administrative oversight or a last-minute correction, as no defects were logged in either test at 156,445 and 156,453 miles. The broader trend over the past three years shows consistent pass rates with no recurring advisories or major faults, indicating the vehicle has not experienced persistent mechanical issues. However, the repeated failures at nearly identical mileages in January 2024 (143,133 and 143,145 miles) warrant scrutiny, as they imply either a temporary testing anomaly or a component nearing failure that was not formally noted. The recorded mileage progression of roughly 6,800 miles annually aligns with typical usage for a vehicle of this age and model. There are no extended gaps suggesting neglect, nor are there abrupt spikes that would indicate aggressive driving or deferred maintenance. The most notable pattern is the January test cycle, where failures occurred within a single week at nearly identical mileages—an unusual but not unheard-of occurrence in MOT history. The consistency of passing tests at other intervals, however, reinforces that the vehicle has been driven regularly without extreme wear patterns. Given the lack of documented defects in recent tests, the primary focus for an in-person inspection should centre on high-wear components that often fail without warning in vehicles of this age. The suspension—particularly the rear bushes and coil springs—should be examined for excessive play or corrosion, as these are common failure points in older Audi A4 models. Brake systems, including caliper binding, disc thickness, and rotor warpage, should be checked, especially if the vehicle has been driven hard or exposed to wet conditions. Structural integrity, particularly around the wheel arches, sills, and subframe, must be assessed for corrosion, as this model is prone to rust-related failures over 20 years. Finally, the exhaust system should be inspected for leaks or cracked pipes, as catalytic converter degradation is a frequent issue in this era of emissions regulation. The absence of advisories does not preclude these areas from requiring attention.
