2017 Audi A4 S Line TDI Quattro S-A 3.0L Diesel · KX66 OBC

The most recent DVSA examination on 11 June 2026 returned a clean pass with no defects or advisories recorded, and this represents a continuation of the positive pattern observed throughout the recorded MOT history. With the exception of a single failure on 28 September 2023 which curiously shows no associated defects, the vehicle has achieved successive passes at the 2022, late 2023 (re-test), 2025, and 2026 tests. The absence of any advisory notes across these examinations is particularly encouraging on a nine-year-old Audi A4, as advisories commonly surface for wear items such as brake pads, discs, tyres, and suspension components approaching their service thresholds. The stable and consistently clean trajectory suggests that the previous keeper has maintained the vehicle to a satisfactory roadworthy standard and addressed deteriorating components before they escalated into failures. Against the vehicle's age of nine years, the recorded 96,700 miles equates to an annual average of approximately 10,744 miles, which sits comfortably within the typical range for a UK-registered executive saloon of this vintage. The mileage progression between tests appears broadly consistent, indicating regular use rather than extended periods of standing or, conversely, unusually high-mileage accumulation that might suggest motorway fleet or taxi-style operation. This moderate usage pattern is mechanically favourable: it implies that consumables such as tyres, brake pads, discs, and clutch or automatic transmission fluid have been subjected to normal wear cycles rather than extreme conditions, while the absence of long standing periods reduces the likelihood of seized calipers, perished rubber components, or severe underbody corrosion. Despite the spotless MOT record, prospective buyers should not treat the clean history as a substitute for a hands-on inspection. Given the vehicle's age and diesel drivetrain, particular attention should be paid to the timing belt or cam belt replacement interval; if the original schedule at around 80,000 miles or five years has not been evidenced by service history, this becomes an immediate priority. The diesel particulate filter should be confirmed as healthy through observation of any dashboard warning lights and by ensuring the vehicle regularly completes sufficiently long journeys to allow active regeneration. A test drive should focus on listening for any irregular knocking from the suspension, which could indicate worn control arm bushes, anti-roll bar drop links, or top mounts typical of this generation of A4. Brake feel should be assessed for any shuddering under gentle application, suggesting warped front discs, and the steering should remain precise without vibration, which could indicate worn front suspension components or imbalanced wheels. Additional checks appropriate to the vehicle's age and usage include a thorough inspection of all four tyres for sidewall perishing and cracking, as rubber compounds degrade with calendar age regardless of tread depth. The 12V battery, now nine years old, is almost certainly due for replacement and should be load-tested rather than simply voltage-checked. Brake discs, particularly the rear units on a Quattro model, are susceptible to corrosion from standing and should be examined for any binding calipers by ensuring smooth rotation when the wheels are free. Engine oil and coolant should be checked for contamination and correct levels, with confirmation that the longlife service schedule has been adhered to, and the automatic gearbox fluid, if not previously changed, may warrant attention on a vehicle approaching 100,000 miles. Finally, a close visual examination of the underbody, suspension arms, exhaust system, and Quattro drivetrain components for any surface corrosion or oil leaks would provide valuable reassurance before purchase.
