Our Verdict
Exercise caution with this high-mileage, large-displacement 2004 Audi A6 petrol saloon. The vehicle has a history of initial MOT failures followed by prompt rectifications, but its complex 4.2-litre engine and significant mileage demand thorough mechanical scrutiny.
When inspecting this 2004 Audi A6, verify the physical service history to correlate with the 177,132 recorded miles, as the MOT data only captures test outcomes. Budget for potential higher-than-average maintenance costs associated with a high-mileage 4.2-litre luxury saloon. Negotiate the price based on the vehicle's age, mileage, and the complex nature of its large petrol powerplant.
Examine the documentation carefully to understand what caused the initial MOT failures recorded on 2023-05-06 and 2025-01-06, even though specific defect descriptions were not logged. Ensure that all major mechanical components, particularly suspension arms and headlamps which are common failure points for this model family, have been recently checked or replaced.
Running a 4172cc petrol engine from 2004 involves substantial outlays. Fuel economy will be low by modern standards, particularly given the large engine displacement and weight of the A6 saloon. Vehicle Excise Duty (road tax) for a 2004 high-capacity petrol car falls into the highest VED brackets.
Insurance costs will likely be high due to the vehicle's performance capabilities, age, and high insurance group rating. Combined with regular maintenance for a high-mileage luxury vehicle, the estimated annual running cost will be significant. Typical annual running costs are estimated at £2,500-£3,200 covering fuel, high-tier tax, insurance, and routine upkeep.
Pay close attention to the suspension system, specifically checking suspension arms for wear or play, as this is a leading MOT failure reason for the model. Inspect the headlamps for clouding, alignment issues, and electrical integrity, which also rank among the top failure categories.
Examine the tyres thoroughly across all four corners for tread depth, age cracking, and uneven wear patterns, as tyres are another common MOT fail point. Given the 4.2-litre engine, listen carefully for any timing chain rattles or coolant leaks during a cold start, and verify the operation of all ancillary electrical equipment.
This black 2004 Audi A6 features a large 4172cc petrol engine and has covered 177,132 miles as of February 2025. Its MOT history shows a pattern of initial failures in both 2023 and 2025 at the exact same mileage before passing shortly after. The recorded mileage sits well above the national average for a vehicle of this age, reflecting heavy use over its lifetime.
Across 143,357 analysed vehicles, the Audi A6 achieves an average MOT pass rate of 84.5%, though high-mileage examples frequently encounter issues with tyres, headlamps, and suspension arms.
