2009 Audi A4 2.0L Diesel · SW59 DZJ

The 2009 Audi A4 presents a solid roadworthiness record, with the most recent MOT on 14 March 2026 at 247,538 miles passing cleanly with zero defects. That is a strong indicator of current mechanical health. The maintenance trend over the last four years is stable and broadly improving. The vehicle failed its December 2022 test at 216,831 miles, then passed in January 2023 at 216,837 miles, and has recorded two subsequent passes with no defects, including a retest on the same day in November 2024 at 240,028 miles. No recurring faults appear in the record, which suggests any earlier issues were addressed and have not returned. Mileage accumulation tells a clear story of sustained high use. Between the January 2023 pass at 216,837 miles and the November 2024 test at 240,029 miles, the car covered roughly 23,192 miles in just under two years, averaging close to 12,000 miles annually in that window. The jump from November 2024 to March 2026 is minimal at around 7,500 miles over approximately fifteen months, indicating a notable drop in usage or a period of lighter driving recently. At an overall average of roughly 14,561 miles per year across its seventeen-year life, this is a high-mileage example, and that level of use places accelerated wear on drivetrain mounts, suspension bushes, brake components, and exhaust systems. Despite the clean MOT record, a buyer should still carry out a thorough physical inspection focused on areas that high-mileage Audi A4s of this generation commonly develop issues with, even when no advisory appears on the test. Front suspension lower arm bushes and track rod ends should be checked for play and perishing, as these wear faster under sustained motorway use. Rear suspension coil springs and dampers merit close attention for sag or weeping. Brake discs and pads should be measured for thickness and uneven wear, particularly at the rear where binding calipers have been a known issue on this platform. The exhaust system, including the DPF-equipped diesel variants common in this model year, should be inspected for leaks, excessive soot, and correct emission function. Structural integrity beneath the car deserves equal scrutiny. Subframes, inner wing arches, and sill edges should be probed for corrosion, especially if the vehicle has spent years on salted roads. Engine and gearbox mounts should be assessed for deterioration, and any signs of oil weeping from the cam cover gaskets or rear main seal should be noted. A clean MOT record is encouraging, but on a high-mileage car of this age, physical inspection remains essential to confirm that the underlying mechanical condition matches the paperwork.
