I have a strange fault on my E46 2002 330ci with the central locking.
The issue is that the passenger side lock does not open when central unlocking is activated from the key fob and the in car unlock button near the gear stick. However central locking works fine.
The only change I've made on the car since the fault is installing a new ICE head unit through a professional installer and they have assured me that the installation is independent of the central locking electrical.
Can anyone advise me if there is any obvious settings I've missed or is the fault more complicated?
