Just thought I'd reply with this. Found this great website showing what every fuse does and whether it goes through ignition relay or not. Will come in use to someone no doubt. Attached pic of fuses I looked at and whether always on or ignition switched. This is for the driver footwell fuse box (RHD UK Car) 320d xDrive
