I know that this is an almost standard fault on the E36, but I canīt find a solution in the other threads, because my cars symptoms is a bit different.
When I lock the car, all locks lock but only for a second before every one but the drivers become unlocked. But if I lock it from the passenger side all it does is lock that door. No sound or movement from anywhere else.
The car is a 316i -91 sedan.
Any help would be welcomed.
