The third-generation BMW 1 Series, chassis F40, marked the model’s switch to front-wheel drive in 2019, sharing its UKL platform with the MINI and 2 Series Active Tourer. Managed by BMW’s Condition Based Service system, the BMW 1 Series Mk3 F40 (2019-Present) tracks maintenance electronically and needs those counters reset after the work. Common procedures include the engine oil service reset, the brake-fluid and microfilter CBS items, and a brake pad wear reset together with the wear sensor. Fitting a new battery requires registration through the power-management module so charging recalibrates, while a steering angle reset follows alignment and a TPMS reset re-baselines tyre monitoring. Open the F40 service reset you need from the procedures listed below.
