2015 Audi A6 S Line TDI Ultra 2.0L Diesel · YC14 RAN

As a 2.0L diesel, this Audi A6 is designed for efficient long-distance cruising, though running costs will be influenced by its high mileage and potential wear-and-tear items. You should expect moderate fuel economy typical of the TDI Ultra technology, but maintenance costs may rise as the vehicle approaches the 200,000-mile mark.

Tax and insurance will depend on the specific tax band and the driver's profile, but the S Line trim typically sits in a mid-to-high insurance group. Budget for more frequent servicing and potential repairs to suspension and braking systems due to the heavy usage patterns observed.

First, inspect the suspension system. The aggregate data for this model identifies suspension arms as a frequent cause of MOT failure, so look for play in the bushings or uneven tyre wear. Given the recent MOT failures in 2024 and 2025, check that any previous issues have been fully rectified with quality parts.

Secondly, inspect the engine bay and underside for signs of oil leaks, which can be common on high-mileage diesel engines. Check the condition of the tyres and brakes, as these are standard MOT focus areas. Finally, ensure the electronic systems and S Line specific interior trim are in good order, as high-mileage vehicles can often show significant wear in the driver's area.
