Verdict

Good choice, check first

Compacte premium 5 étoiles Euro NCAP (2020), coffre de 380 litres. Plusieurs rappels de sécurité ont touché les exemplaires 2020-2022 (freins, ceintures, airbag passager, fusible haute tension des hybrides rechargeables) : faites vérifier au numéro de série qu'ils ont été traités. L'embrayage de la boîte S tronic à embrayages secs mérite un essai attentif.

You are importing the car to:

Import penalty (malus) in France

  • Emissions of the versions in this guide: 128 g CO₂/km (check the value on the car's registration certificate).
  • 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.

Check an imported car's history

HistoVec only covers the vehicle's life in France. For a car coming from abroad, a VIN-based report helps spot inconsistent mileage or a reported accident.

Known faults

Note: some faults below are cited by a single source only. They are still to be confirmed and the reliability score is only indicative.

Embrayage et bruits de pédale

Severity 2/3 · Costly

Fiches-auto relève sur une A3 35 TFSI 2021 à boîte DQ200 un embrayage signalé dès 30 000 km, remplacé pour 2 600 € selon le témoignage rapporté par CarVerif (un cas isolé, pas un tarif). Un autre propriétaire décrit un bruit et un craquement sous la pédale d'embrayage, constaté plusieurs fois en concession.

Défauts d'infotainment (MMI) des premières séries

Severity 1/3 · Annoying

Les premières A3 8Y (2020-2021) ont connu des défauts du système MMI, améliorés par des mises à jour logicielles ; vérifier la version logicielle à l'achat. Source unique, et des propriétaires de Fiches-auto jugent au contraire le système sans bug.

Inspection checklist

Things to check

  • Faire vérifier au numéro de série, chez Audi, les rappels freins, ceintures, airbag passager (et fusible haute tension sur la 40 TFSI e).
  • Essayer l'embrayage ou la boîte S tronic à froid : à-coups, broutement, craquement sous la pédale.
  • Tester l'écran MMI, les aides à la conduite et la caméra ; demander la version logicielle.
  • Sur la 40 TFSI e, contrôler le câble et la charge à la prise domestique ou à la borne.
  • Exiger le carnet d'entretien Audi et les factures.

Questions to ask the seller

  • Les rappels freins, ceintures et airbag ont-ils été effectués ? Avez-vous les attestations ?
  • L'embrayage ou la boîte a-t-il déjà donné lieu à une intervention ?
  • Le logiciel du système multimédia a-t-il été mis à jour ?

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.
