My E90 320i central locking will get unlocked / locked randomly while I'm driving the car and squeaking sound from the locking
mechanism at times (while the door remained locked).
Otherwise, I can lock / unlock via FOB with no problem and auto lock setup at 20km/h is working too.
Search the forum and doesn't seemed to be similar to the fuse issued reported. My battery reading is at 14.0+v too.
Appreciate any comments as to what could be the caused of this problem.
