Used Audi RS6 for sale in Europe

About the Audi RS6

The Audi RS6 is the high-performance version of the A6, sold mainly as an Avant estate. It pairs a large boot with a twin-turbocharged engine and quattro four-wheel drive. It suits buyers who want family-car space and the ability to cover long distances quickly.

Four generations are on sale across our listings. The first two used a V8 and a V10 respectively. The third and fourth use a 4.0-litre twin-turbo V8. The newest cars add 48-volt mild-hybrid technology, which is why hybrid appears among the fuels in our listings. Gearboxes are automatic across the range.

Age and specification vary widely between generations, so inspection priorities differ. Older cars depend heavily on documented servicing and on the condition of complex suspension and cooling parts. Newer cars are more about options, software and the condition of wheels, tyres and brakes.

Generations

• C5 (2002-2004) — Used a 4.2-litre twin-turbo V8 with an automatic gearbox and quattro, and was offered as an Avant and as a saloon.

• C8 (2019-present) — Kept the 4.0-litre twin-turbo V8 and added 48-volt mild-hybrid assistance, with an eight-speed automatic gearbox and quattro.

What to check when buying a used Audi RS6

Ask for the full service history and look the car over in daylight, then have a specialist check it, ideally with a diagnostic scan. Compare the paperwork with the car's condition, because these cars are often driven hard.

• Service history and records

  Look for regular oil changes and invoices from a workshop that knows high-performance Audis. Gaps in the record matter on an engine with turbochargers and tight packaging. Ask what major work has been done and whether any is due.

• Brakes, tyres and wheels

  These cars are heavy and fast, so brakes and tyres wear. Check disc and pad condition, uneven tyre wear that might point to alignment problems, and kerb damage on the large wheels. If ceramic brakes are fitted, ask for an inspection report.

• Suspension and cooling parts · C5 (2002-2004)

  The C5 used a linked hydraulic suspension system and a packed engine bay with several turbo-related hoses and coolant parts. Check for leaks, warning lights and uneven ride height. Ask whether the timing belt service has been done and when.

• V10 engine health · C6 (2008-2010)

  The V10 is a complex engine, so a specialist inspection is sensible. Check for warning lights, rough running, oil leaks and signs of overheating. Ask what servicing has been done on the engine and gearbox, and check the suspension for faults.

• Air suspension and electronics · C7 (2013-2018)

  Check that the air suspension raises and lowers evenly and that no warning messages appear. Test the infotainment, driver assistance features and all switches. Ask whether the car has been tuned, since power upgrades change the load on the drivetrain.

• Software and mild-hybrid system · C8 (2019-present)

  Have the dealer or a specialist check for open software updates and stored fault codes, including those for the 48-volt system. Check that every optional feature fitted works, and compare the options on the car with the original specification.

• Signs of modification or damage

  Look for uneven panel gaps, mismatched paint and non-standard exhaust or engine software. Modified cars may have different wear patterns and the work is not always documented. Ask for the car's history and any proof of professional installation.
