Our Verdict
Recommended with caution due to a single corrosion-related MOT failure, but overall solid condition for its age.
Prioritise a thorough inspection of the corroded offside rear coil spring mounting, as corrosion can worsen over time. Verify service history to confirm regular maintenance, particularly for the petrol engine. Be prepared to negotiate slightly due to the above-average mileage and the need for potential corrosion checks. Look for any signs of water ingress or additional rust in the underbody areas.
Petrol fuel economy is moderate, with an estimated 35-40 mpg. The vehicle falls into a higher UK road tax band due to its petrol engine. Insurance group 15-20 is typical for this model, with annual premiums around £1,000-£1,200. Maintenance costs for premium Audi models are generally higher, with £300-£500 annually for routine services and parts.
Focus on the rear suspension area where corrosion was recorded, checking for structural weakening or further rust. Inspect the underbody for additional corrosion, especially around the chassis and exhaust system. Test the petrol engine for smooth operation and check for any warning lights on the dashboard. Verify that all electronic systems (e.g., infotainment, driver assistance) function correctly.
This 2021 Audi A6 S Line 40 TDI MHEV S-A has a mostly clean MOT history, with only one minor corrosion issue recorded in 2026. The mileage of 40,596 miles is slightly above average for a five-year-old vehicle, but the car appears well-maintained. The petrol engine variant is less common for this model, which may affect running costs.
No aggregate data available for this specific model, but the vehicle's MOT history shows no major recurring issues.
