The Audi A3 set the template for the upmarket compact, pairing a polished interior with engineering shared across the Volkswagen group. Like its siblings, it relies on a flexible service regime that has to be reset by hand once you have carried out the work, or the long-life service prompt will keep nagging you. Typical tasks owners handle themselves are the oil service reset, clearing the maintenance interval, a TPMS reset to re-store tyre pressures, electric window reinitialisation after a battery change and recalibrating the steering angle on cars fitted with stability control. Because the dash interface evolved considerably across A3 generations, our guides are grouped by generation to match your exact build. Choose yours below to open the relevant procedures.
