The second-generation DS 4 2021-Present moved onto the EMP2 platform as a sharper, more upmarket compact hatch with the DS Iris infotainment system and plug-in hybrid options. Its electronics-rich design means that after any service the car keeps the previous maintenance status displayed until each system is reset. Owners commonly need the oil service reset, the maintenance reminder reset, a TPMS reset after tyre changes, and on PHEV models confirmation of the 12V battery after replacement. Browse the guides below to perform the exact reset your DS 4 requires.
