2011 Audi A5 2.0L Diesel · SM11 YNH

The 2.0 TDI diesel in this A5 should return around 45-50 mpg in real-world driving, though city driving may see closer to 38-42 mpg. Road tax for a 2011 diesel sits in a higher band than petrol equivalents due to post-2007 emissions-based VED rules, so expect around £200-£260 annually depending on exact CO2 output. Insurance for a 17-plater driver typically falls in groups 30-32, costing £600-£900 per year depending on location, age, and driving history.

Annual maintenance for a high-mileage Audi A5 diesel at 141,000 miles is realistically £500-£800 for routine servicing, plus a contingency fund for age-related repairs. Major items likely due or approaching include brake discs and pads (front and rear), suspension components (the model's top MOT failure reason), and potentially tyres. The estimated annual running cost combining fuel, tax, insurance, and maintenance sits at approximately £2,800-£3,500 for a typical driver.

The most critical inspection point for this specific vehicle is establishing why two MOT tests in late 2024 and late 2025 were recorded as failures with no defects listed. Ask the seller directly, request any paperwork from the testing station, and check with the DVSA if necessary — this pattern is unusual and must be resolved before purchase. Physically inspect the vehicle's condition carefully, as the MOT record alone does not confirm mechanical soundness.

For the 2011 Audi A5 specifically, pay close attention to the suspension arms, bushes, and anti-roll bar links — these are the top MOT failure category for this model across all 131,081 vehicles analysed. Inspect brake pad and disc wear both visually and by feel, as the second most common failure. Check tyre condition and tread depth across all four corners plus the spare. For the 2.0 TDI engine at 141,000 miles, listen for timing chain rattle on cold start (early signs of tensioner wear), check for excessive smoke from the exhaust on startup, and verify the DPF is functioning correctly with no warning lights illuminated on the dashboard. Test the dual-clutch automatic (if fitted) for smooth changes, or the manual gearbox for any synchro wear in second and third gears.
