The sixth-generation BMW 3 Series spanned the F30 saloon, F31 Touring and F80 M3, produced from 2011 to 2020 on BMW’s first widely turbocharged 3 Series platform. With its iDrive-managed CBS (Condition Based Service) system, the BMW 3 Series F30/F31/F80 (2011-2020) tracks each maintenance item electronically and needs those counters reset after the work is done. Typical resets include the engine oil service reset, the microfilter and brake-fluid CBS items, and a brake pad wear reset paired with the appropriate sensor. After a battery swap, registration through the power-management module is essential, and a steering angle reset is standard following alignment. A TPMS reset re-baselines the tyre monitor after a pressure change. Pick the F30/F31 service reset you need from the procedures listed below.
