FEXON's rear tailgate trunk latch actuator is a direct-fit replacement that restores locking and unlocking function for compatible Mercedes-Benz ML and E-Class models.

If the liftgate on your Mercedes-Benz no longer locks or unlocks reliably, a failed latch actuator is often the cause. This FEXON replacement unit is designed to match the original mounting and electrical connections for a straightforward swap, with internal motor and gear components engineered for long service life.
