2009 Audi A3 S Line 138 TDI 2.0L Diesel · XLZ 6323

The most recent MOT on 14 February 2025 recorded a pass with no defects, following two earlier failures in January and early February of the same year that also listed no faults. Those failures were almost certainly administrative – perhaps a missed test or paperwork issue – rather than indicative of mechanical problems. With a clean pass in July 2023 and no recorded defects in any of the four entries, the vehicle’s maintenance record appears stable and shows no trend of deteriorating condition. At 180,948 miles the 2009 Audi A3 S line has accumulated roughly 10,600 miles per annum over its 17‑year life, which sits squarely within normal usage for a compact executive hatchback. There are no obvious long‑term storage periods or sudden mileage spikes that would suggest either excessive wear from high‑speed touring or prolonged inactivity that can cause component seizing. The mileage level does, however, mean that many wear items – such as suspension bushings, engine mounts, and drivetrain components – are likely approaching the latter stages of their service lives and should be inspected closely. For a buyer, the first visual checks should focus on the tyre condition: examine tread depth, sidewall cracking or dry rot, and look for uneven wear that could signal mis‑aligned suspension or worn camber/caster bushes. Verify that the tyres are not more than six years old, as rubber perishes with age regardless of mileage. The 12‑volt battery, now approaching a decade, should be tested for cranking voltage and electrolyte level (if serviceable), and the terminals inspected for corrosion that can cause intermittent starting issues. Inspect the wheel arches and under‑carriage for rust, especially around the wheel wells, sills and rear subframe, as prolonged standing can accelerate corrosion on a vehicle of this age. Given the mileage, the brake system warrants a thorough examination: check the discs for surface rust, scoring or thinning, and ensure the pads have sufficient material and are not glazed. Bindings in the calipers can manifest as a pulsating pedal or uneven pad wear, so a test‑drive should include a firm, progressive brake application to feel for shudder or pull. The suspension should be assessed for play in the front struts, worn coil‑spring mounts, and deteriorated rubber bushes, which often produce clunking over bumps. Finally, confirm that the timing belt (or chain, depending on the exact TDI variant) has been replaced in line with the manufacturer’s interval – typically around 100 000 miles – and that the DSG clutch and fluid have been serviced, as neglect here can lead to costly transmission failure. A full service history and recent oil change records will give further confidence that the vehicle has been kept within its prescribed maintenance schedule.
