2014 Audi A6 S Line TDI Ultra S-A 2.0L Heavy oil · SH14 MPU

Consistent roadworthiness is the primary characteristic of this Audi A6, which has maintained a clean MOT history throughout its testing life, including the most recent pass on 28 May 2026. While the record shows a procedural failure on 22 May 2026, the absence of any recorded defects across the entire history suggests that the vehicle has avoided the recurring mechanical failures or structural degradation often seen in high-mileage diesel saloons of this vintage. The lack of documented advisories indicates that common wear items such as suspension bushes, brake pipes, and exhaust components have either been replaced proactively or have not yet reached the threshold for formal tester notification. Accumulating 105,568 miles over a twelve-year period results in an average annual usage of approximately 8,797 miles, a figure that sits comfortably within the expected range for a vehicle of this class. This steady, moderate usage pattern typically places less strain on the drivetrain compared to high-mileage fleet examples, though it does mean that original components are now entering a stage where age-related fatigue becomes a factor. There are no significant gaps in the testing history to suggest extended periods of dormancy, which is a positive indicator for the longevity of rubber seals, gaskets, and electronic modules that can otherwise suffer from prolonged inactivity. Despite the clean MOT record, the test drive remains the most critical phase of your evaluation, particularly regarding the S-tronic transmission and the TDI engine. During your inspection, pay close attention to the gear changes; any hesitation, judder, or metallic clunking when shifting between first and second gear, or when moving between drive and reverse, may indicate internal wear within the dual-clutch unit. Furthermore, listen for any rhythmic knocking or clicking from the front suspension when traversing uneven surfaces, as the control arm bushes and ball joints on this chassis are known to wear over time, even if they have not yet been flagged during a static inspection. The braking system and steering rack also warrant specific scrutiny during your road test. Ensure the vehicle tracks straight under heavy braking and that there is no pulsing sensation through the pedal, which would suggest warped discs or uneven pad wear. Given the vehicle's age, check the steering for any play or vagueness, and observe the exhaust tailpipes for excessive blue or black smoke under hard acceleration, which could point to turbocharger oil seal wear or DPF saturation issues. Because the MOT does not assess the internal condition of the engine or the longevity of the transmission, a cold start is essential to listen for timing chain rattle, a known consideration for this engine architecture.
