2014 Audi A6 S Line Black Edit TDI QUT A 3.0L Diesel · Y30 ATC

As a 3.0-litre diesel, this A6 is a capable long-distance cruiser, though it will be more expensive to run than smaller-engine alternatives. Expect reasonable motorway fuel economy, but be prepared for higher tax brackets and insurance premiums associated with a high-performance executive diesel.

Maintenance costs for an Audi of this age can be significant if major components fail. Budgeting for specialist independent servicing rather than main dealer rates is recommended to keep annual costs manageable. You should anticipate an estimated annual running cost of £1,800-£2,200, accounting for fuel, VED, insurance, and routine maintenance.

Focus your physical inspection on the condition of the tyres and brakes, as the Quattro system can be demanding on these components. Check the alloy wheels for signs of kerbing, especially given the 'Black Edition' styling which often features larger, more vulnerable rims.

Verify that all electronic systems are functional, particularly the MMI infotainment screen and the climate control system, as these can be costly to repair if they develop faults. While the recent MOT history is clean, ensure the underside is inspected for any signs of oil leaks around the engine and gearbox, which are common areas of concern for high-mileage V6 diesels.
