Used Audi S8 for sale in Europe

About the Audi S8

The Audi S8 is the high-performance version of the A8 luxury saloon. It combines a large, comfortable body with a powerful petrol V8 or V10 and quattro all-wheel drive. It suits drivers who want long-distance comfort and strong acceleration in a body that looks fairly restrained.

The S8 has been sold as a four-door saloon with automatic gearboxes and permanent all-wheel drive. Earlier cars have naturally aspirated engines. Later cars use a twin-turbo V8, and the newest versions add a mild hybrid system. The listings also include a few LPG cars.

Cars across the range are complex and expensive to maintain properly. Condition and documented servicing matter more than age alone. Compare cars by generation first, because equipment, engines and running costs differ a lot between them.

Generations

What to check when buying a used Audi S8

Ask for the full service history and inspect the car in person or through an independent specialist. Aim for a cold start and a long test drive that includes hard acceleration and low-speed manoeuvring.

• Service history and invoices

  Look for regular oil changes and gearbox servicing, with invoices from a specialist or franchised dealer. Large gaps or missing records on a car this complex are a reason to look at another example or ask for an inspection.

• Air suspension and ride

  Many S8 cars use air or adaptive suspension. Check that the car sits level after standing, that no warning lights show, and that the ride is smooth over bumps. Worn parts and leaks can be costly to put right.

• Age-related wear and engine service · D2

  These cars are now old. Check the timing belt service record on the V8, plus cooling system condition, rubber parts and electrics. The aluminium body needs specialist repair after damage, so look carefully for signs of past accidents.

• V10 engine and oil leaks · D3 (V10)

  Check for oil or coolant leaks, uneven idle and warning lights. Ask for evidence of maintenance. Direct-injection engines can build up deposits over time, so a rough start or hesitation deserves a closer look by a specialist.

• Turbo V8 health · D4 and D5 (twin-turbo V8)

  Check for oil leaks, stored fault codes and any cooling system problems. Make sure all software updates and recalls have been carried out, and ask the seller for proof. Listen for unusual noises during hard acceleration.

• Mild hybrid and electronics · D5

  Test the start-stop function, the infotainment system and all driver-assistance features. Check that no hybrid or battery warnings appear. Ask the seller for documentation of software updates and any warranty that remains.

• LPG conversions

  If a car runs on LPG, ask who fitted the system and when, and request the paperwork. Check the tank, the lines and the servicing records, and confirm that the conversion is accepted in the country where you plan to register the car.
