The third-generation Hyundai i20, project code BC3, arrived in 2020 with sharper styling, mild-hybrid options and the performance i20 N flagship. As a modern supermini packed with electronics, the Hyundai i20 Mk3 BC3 (2020-Present) often needs a reset once servicing is complete. The oil service reset clears the maintenance reminder through the instrument cluster, while a TPMS reset returns the tyre monitor to normal after a pressure adjustment or wheel swap. Renewing the brake pads calls for a brake pad wear reset, and on mild-hybrid versions the 12V battery is best reset after replacement so charging adapts. The auto-up windows may also need re-initialising after a battery disconnection. Find the i20 reset that fits your repair in the list below and work through it.
