Typical Price Range
All prices are approximate and subject to change based on condition, mileage, specification, and market conditions.
- 2015–2018: £10,000 – £20,000 — Predominantly C7 generation (facelifted) models, offering modern tech and efficient engines. Prices vary greatly by mileage, trim, and engine choice.
- 2019–2021: £22,000 – £35,000 — Early C8 generation cars, featuring more advanced infotainment, mild-hybrid technology, and a sharper design. Prices are sensitive to specification.

Common Issues to Check
- DSG/S Tronic gearbox issues: Some models, particularly with higher mileage, can experience hesitation or clunking. Check service history for gearbox oil changes.
- MMI (Multi Media Interface) system glitches: Software bugs or component failures can occur. Ensure all functions work correctly during a test drive.
- EGR valve and DPF (Diesel Particulate Filter) problems: Especially in diesel models used predominantly for short journeys, check for DPF warning lights or rough running.
- Suspension components: Worn bushes or linkages can lead to knocking noises or imprecise handling. Listen for unusual sounds over bumps.
- Electrical gremlins: Intermittent issues with warning lights, sensors, or auxiliary systems. A full diagnostic scan is advisable before purchase.
Running Costs
- Fuel Economy: 30-55 mpg (petrol), 40-65 mpg (diesel), depending on engine and driving style. Mild-hybrid models can offer improved urban economy.
- Insurance Group: Group 29-45, depending on engine size, trim level, and age. Expect higher premiums for performance-oriented S line or 'S' models.
- Servicing: Regular servicing (typically every 10,000 miles or annually) is crucial. Costs can be higher at Audi dealerships, but independent specialists offer competitive rates. Budget for major services every few years, which may include gearbox oil changes.
Which Variant Should I Choose?
- 2.0 TDI S line: Perfect for company car drivers or families seeking a balance of fuel efficiency, sporty aesthetics, and comprehensive equipment. The 2.0 TDI engine offers ample power for UK motorways, and S line trim adds a more aggressive look and improved interior amenities.
- 3.0 TDI Quattro Black Edition: Ideal for those desiring stronger performance, enhanced traction, and an imposing road presence. The 3.0 TDI V6, particularly with Quattro all-wheel drive, provides effortless acceleration, while the Black Edition trim adds darkened styling elements and a higher specification for a luxurious yet stealthy look.
- TFSI e (Plug-in Hybrid): An excellent choice for eco-conscious urban commuters or company car drivers looking to minimise their BIK tax liability. These models offer a substantial electric-only range, making them ULEZ compliant and reducing fuel costs for shorter journeys, while the petrol engine provides flexibility for longer trips.
- 40 TFSI Sport: A great all-rounder for private buyers prioritising comfort and refinement over outright performance. The 2.0-litre petrol engine is smooth and responsive, while the Sport trim offers a good level of standard equipment without the firmer ride of the S line and often at a more accessible price point.
