2017 Audi A4 1.4L Petrol · LS17 GAO

With a five-test DVSA record entirely free from advisories and only one isolated failure that returned no defect details, this 2017 Audi A4 presents an unusually clean mechanical profile for a nine-year-old executive saloon. The most recent examination on 22 September 2025 concluded with a clean pass and no advisories, continuing a pattern of straightforward roadworthiness outcomes stretching back to 2022. The single fail recorded on 26 September 2024 was followed just thirteen days later by a pass on 9 October 2024 with no defects, which strongly suggests an intermittent or advisory-level issue rather than a structural or systemic defect. Overall, the trajectory is stable and reassuring rather than progressive deterioration, though the absence of recorded advisories also means there is no granular component data to confirm wear rates on items like brake pads, tyres, or suspension components. The recorded mileage of 43,278 miles against a nine-year vehicle age equates to an annual accumulation of roughly 4,800 miles, which is well below the typical usage rate for a vehicle of this class. While low mileage reduces general wear on major drivetrain components, it can also indicate extended periods of standing, which encourages specific issues such as brake disc corrosion, brake caliper slide seizure, dry rubber seals, and flat-spotted tyres. There are no significant gaps in annual testing visible in the record, with tests consistently falling in September or October, suggesting the vehicle has remained in active use throughout the period covered. The mileage progression between tests appears steady rather than showing sudden spikes, which is consistent with regular light use rather than a high-mileage commuter pattern that has since slowed. Given the absence of any recorded advisories across five tests, the buyer cannot point to any flagged component and should therefore prioritise a thorough physical inspection of the areas most commonly affected on a 2017 A4. On a test drive, pay particular attention to the front suspension, as worn upper or lower control arm bushes and failing anti-roll bar drop links are frequent findings on this chassis; listen for clonks or knocks over speed humps and uneven surfaces, and feel for any vagueness through the steering wheel that might indicate worn tie rod ends. Brake feel should be assessed for a spongy pedal suggesting corrosion in the flexible hoses, and any judder under braking could point to warped front discs, particularly if the vehicle has spent extended periods standing between short trips. The engine and transmission should also be inspected for the tell-tale signs of a low-mileage vehicle that has been used sporadically. On cold start, listen for any timing chain rattle from the upper front of the engine, as the EA888 and earlier EA888 generation units fitted to A4s of this era can develop chain tensioner wear that only becomes audible before oil pressure builds. Check for any oil seepage from the cam chain cover, turbo oil feed pipes, and the valve cover gasket, all known areas on this engine family. For the automatic gearbox, ensure smooth and prompt gear changes without hesitation or flare, and confirm the haldex or front differential on quattro variants is operating without vibration or binding on full-lock turns. A compression test or diagnostic scan for fault codes would be a worthwhile precaution given the low annual mileage, helping to confirm internal engine health before purchase.
