2019 Audi A4 Technik 35 TDI S-A 2.0L Diesel · WN69 GZX

The vehicle most recently passed its MOT on 21 October 2025 with no defects recorded, indicating a current state of roadworthiness. Looking at the historical data, the maintenance trend appears stable. While there was a failure in December 2023, this was strictly related to tyre tread depth, which is a routine consumable item rather than a sign of systemic mechanical neglect. The subsequent clean passes suggest that the vehicle is being kept in a condition that meets minimum safety standards. The recorded mileage of 116,141 miles is high for a seven year old vehicle, averaging approximately 16,592 miles per year. This level of usage typically indicates extensive motorway travel, which is generally less stressful for the engine than urban stop-start driving, but it does accelerate the wear of critical components. At this mileage, the buyer should expect increased wear on suspension bushes, wheel bearings, and the drivetrain, and must verify that major scheduled maintenance has been performed to prevent premature component failure. Given the high mileage and the relatively clean MOT record, the focus of a physical inspection should shift toward long-term wear and service history. It is imperative to verify the service book for evidence of timing belt and water pump replacement, as these are critical failure points for this engine at this age and mileage. During a test drive, listen for suspension clunks or knocks and feel for any shuddering through the steering wheel, which could indicate worn control arm bushes or degraded coil springs. Pay close attention to the S-Tronic transmission for smooth gear transitions and any hesitation, as high-mileage automatic gearboxes require strict adherence to fluid change intervals. Further inspection should include a thorough check of the braking system for disc corrosion or uneven wear, and a verification of the tyre brand and age to ensure they are not perishing or mismatched. For a diesel of this mileage, checking for signs of oil leaks around the engine block and verifying the health of the diesel particulate filter via a diagnostic scan or by observing exhaust emissions is advised. Finally, ensure the 12V battery is holding a strong charge and that there are no signs of fluid degradation, such as milky oil or contaminated coolant, which would suggest internal engine issues.
