The third-generation Audi A3 8V (2012–2020) moved onto the VW Group MQB platform, sharpening the hatchback, Sportback and Saloon with a fully digital instrument binnacle on later cars. With so much electronics on board, several systems expect a reset once you’ve carried out maintenance or fitted new parts. After an oil change you’ll want the oil service reset done through the Audi MMI/driver display, and the longer-life inspection counter cleared in the same menu. Owners also tackle a TPMS reset after rotating wheels, brake pad wear sensor reset when the front discs are renewed, and steering angle calibration following suspension or tracking work. If a new 12V cell has gone in, battery registration tells the charging strategy about it. Pick the exact service reset walkthrough you need from the list of procedures below.
