You are importing the car to:
Import penalty (malus) in France
- The CO₂ malus follows the scale of the year the vehicle was first registered, in France or abroad (WLTP or NEDC scale depending on its registration certificate).
- For an imported used car, it is reduced by a flat-rate discount based on its age in months (scheme in force since 1 March 2025). The weight malus also applies on first registration in France.
- The malus is zero for a car more than fifteen years old or first registered before 1 January 2015.

Inspection checklist
Audi A6 C8 (4K) — inspection checklist
Things to check
- Faire vérifier au numéro de série, chez Audi, les campagnes de rappel (AdBlue 2019-2021 sur le 2.0 TDI).
- Tester le MMI, les écrans, la synchronisation du téléphone et les aides à la conduite.
- Contrôler l'état de l'AdBlue et le fonctionnement de la pompe sur un diesel de plus de 100 000 km.
- Préférer un kilométrage inférieur à 100 000 km, selon CarVerif.
- Exiger le carnet d'entretien Audi complet.
Questions to ask the seller
- Les campagnes de rappel ont-elles toutes été effectuées chez Audi ?
- Le MMI ou l'électronique ont-ils déjà posé problème ?
- La pompe AdBlue ou le système de dépollution ont-ils été remplacés ?
Test-drive tip: read the fault codes
A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.
