The fourth-generation Mazda 3, chassis BP, launched in 2019 with striking Kodo styling, a refined interior and the option of Mazda’s SkyActiv-X compression-ignition petrol engine. Like any current car, the Mazda 3 Mk4 BP (2019-Present) depends on networked modules that often need resetting once servicing is finished. The most routine task is the oil service reset, which clears the maintenance reminder after an oil and filter change, while a TPMS reset returns the tyre monitor to normal after a pressure adjustment. Owners renewing brake pads should complete a brake pad wear reset, and disconnecting the battery may require the power windows to be re-initialised. A steering angle reset can also be needed after alignment. Select the Mazda 3 reset below that fits the repair you have just performed.
