2016 Audi A6 3.0L Diesel · Y35 SLC

The most recent MOT test conducted in September 2025 resulted in a pass with no defects recorded. Reviewing the overall maintenance trend, the vehicle shows a pattern of reactive maintenance rather than purely preventative. A significant failure occurred in February 2025 due to excessively worn lower suspension arm bushes on both the nearside and offside front. However, the subsequent clean pass suggests these major defects were rectified. The current status indicates the vehicle is mechanically compliant, but the recent failure highlights that wear-and-tear components are actively reaching the end of their functional life. With 129,463 miles recorded, this Audi A6 has covered a substantial distance for a ten-year-old vehicle, averaging approximately 12,946 miles per year. This level of usage is higher than the UK average for this vehicle class and implies a higher degree of mechanical fatigue across the chassis and drivetrain. While consistent mileage often suggests the vehicle has been used regularly rather than sitting idle, the cumulative stress on the suspension, braking system, and engine seals will be more pronounced. Prospective buyers should budget for more frequent maintenance of consumables and potential repairs to high-wear items. During your inspection and test drive, you must pay close attention to the front end of the vehicle. Although the suspension arm bushes were noted as a failure in early 2025, you should listen for any rhythmic knocking, clunking, or shuddering when navigating uneven road surfaces or turning the steering wheel, as these are primary indicators of bush or ball joint degradation. Additionally, check the tyre condition thoroughly. The February 2025 advisory noted a cut in the offside front tyre sidewall; ensure this has been replaced with a new tyre and check all other tyres for uneven tread wear, which could indicate that the suspension geometry was not correctly aligned following the recent repairs. Given the high mileage, a thorough examination of the braking system is essential. Look for excessive corrosion or deep scoring on the brake discs and check for any signs of binding calipers or uneven pad wear. You should also inspect the engine bay and the underside of the vehicle for any evidence of fluid leaks, such as oil or coolant, which can become more prevalent as seals age and mileage increases. Finally, do not rely solely on the MOT history; verify the service book to ensure that critical interval-based maintenance, such as the timing belt and water pump replacement, has been completed, as these are vital for the long-term mechanical integrity of the engine.
