Typical Price Range

All prices are approximate and subject to change based on condition, mileage, specification, and market conditions.

• 2015–2018: £10,000 – £18,000 — Represents the C7 generation, offering excellent value with still-modern features and a wide engine choice. Prices vary significantly with mileage and trim level.
• 2019–2021: £20,000 – £32,000 — Mainly the current C8 generation, featuring more advanced tech, updated styling, and mild-hybrid systems. Expect higher demand and features a digital cockpit.

Common Issues to Check

• MMI (Multi Media Interface) glitches: Can sometimes freeze or be slow to respond, though software updates often resolve this.
• DSG/S Tronic gearbox issues: On higher mileage models, some owners report hesitation or rough changes, particularly with the 7-speed wet-clutch unit. Regular servicing is key.
• AdBlue system problems: Particularly on TDI models, the AdBlue system can develop faults leading to warning lights and sometimes limp mode if not rectified.
• Electrical gremlins: Intermittent issues with sensors, electric parking brakes, or infotainment screens are not unheard of.
• Suspension components: Bushings and control arms can wear on models with higher mileage, leading to knocking noises over bumps and potentially increased tyre wear.

Running Costs

• Fuel Economy: 35 – 55 mpg (depending on engine and driving style), with TDI models offering the best fuel efficiency.
• Insurance Group: Group 28 – 45 (varies significantly by engine size, trim level, and specific variant like the S6/RS6).
• Servicing: Generally moderate to high, in line with a premium executive car. Expect annual services to range from £200-£400 for minor services and more for major services including cambelt replacement (if applicable) or gearbox oil changes. Audi specialist independent garages can offer more competitive pricing than main dealers. Don't forget your annual MOT costs.

Which Variant Should I Choose?

• 2.0 TDI S Line (C7 Generation): Ideal for those seeking a stylish, economical, and well-equipped executive car. The 2.0 TDI engine offers a good balance of performance and fuel efficiency, while S Line trim adds sporty aesthetics and an enhanced interior, making it a popular choice for ULEZ compliance and everyday commuting.
• 3.0 TDI quattro S Tronic (C7/C8 Generations): Perfect for drivers who cover long distances or appreciate robust performance and the added security of quattro all-wheel drive, especially in challenging UK weather. The 3.0 TDI provides smooth, effortless power, and the S Tronic gearbox delivers swift shifts. Great for towing and motorway cruising.
• 40 TFSI Sport (C8 Generation): A strong contender for drivers who prefer petrol engines and appreciate modern technology. The 2.0 TFSI engine offers refined performance and is often paired with mild-hybrid tech for improved efficiency. Sport trim provides a good balance of features and dynamic styling without the higher costs of S Line.
• A6 Avant (All Generations): The estate version is invaluable for families, dog owners, or anyone needing significant cargo space without compromising on luxury or driving dynamics. It retains all the A6's strengths but adds practicality, making it a highly versatile premium vehicle. Check the V5C for body type.
